Induction Pipe Bend is a controlled means of bending pipes through the application of local heating using high frequency induced electrical power. Originally used for the purpose of surface hardening steels, induction technology when used in Pipe Bend consists basically of an induction coil placed around the pipe to be bent. The induction coil heats a narrow, circumferential section of the pipe to a temperature of between 850 and 1100 degrees Celsius (dependant on the material to be formed). As the correct bending temperature range is reached, the pipe is moved slowly through the induction coil whilst the bending force is applied by a fixed radius arm arrangement. Induction Pipe Bends/Spools and air/steam rings Tube Bending are manufactured by the process of induction heating in meeting perse high quality requirements in accordance with ASTM, API, DIN, BS, ANSI, ASME PFI and other international technical specifications. Manufacture of Induction Pipe Bends Induction Pipe Bends are formed in a factory by passing a length of straight pipe through an induction bending machine. This machine uses an induction coil to heat a narrow band of the pipe material. The leading end of the pipe is clamped to a pivot arm. As the pipe is pushed through the machine, a Pipe Bend with the desired radius of curvature is produced. The heated material just beyond the induction coil is quenched with a water spray on the outside surface of the pipe. Thermal expansion of the narrow heated section of pipe is restrained due to the unheated pipe on either side, which causes diameter shrinkage upon cooling. The induction Pipe Bending process also causes wall thickening on the intrados and thinning on the extrados. The severity of thickening/thinning is dependant on the bending temperature, the speed at which the pipe is pushed through the induction coil, the placement of the induction coil relative to the pipe (closer to the intrados or extrados), and other factors. Most induction bends are manufactured with tangent ends (straight sections) that are not affected by the induction Pipe Bending process. Field welds are made or pipe pup sections are attached to the unaffected tangent ends, allowing for fitup similar to that found when welding straight sections of pipe together. Induction Pipe Bends come in standard Pipe Bend angles (e.g. 45°, 90°, etc.) or can be custom made to specific bend angles. Compound bends (out-of-plane) bends in a single joint of pipe can also be produced. The bend radius is specified as a function of the diameter. For example, common bend radii for induction bends are 3D, 5D and 7D, where D is the nominal pipe diameter.

This standard covers induction bends for transportation and distribution piping applications (e.g., ASME B31.4, B31.8, and B31.11). Process and power piping have differing requirements and materials that may not be appropriate for the restrictions and examinations described herein, and therefore are not included in this Standard. ThicknessUpto 14” dia pipe – 5 – 50mm26” – 36” dia pipe – 6 – 36mm38” – 48” dia pipes – 8- 32mm Bending Process The pre-inspected pipe having positive thickness is kept on the pipe carriage and clamped hydraulically on the rear carriage. The induction coil and cooling coils are mounted around the pipe. The concentricity of induction coil is adjusted with 3-plane movement to assure the uniform heating by induction. The radius of bend is fixed by adjusting the radius arm and front clamp. The pointer is also set to the correct degree. The pipe is pushed forward slowly so as to clamp rigidly with front clamp. The pipe is marked for arc length and initial thickness / hardness measurements. Before starting the bending operations the hydraulic pressure / water level / flow switches etc. are checked. The pipe is now heated by induction to the temp of 815 – 995 C. By pushing the pipe by push clamp the bending of the pipe is started slowly and carried out at speed of 10 – 40 mm/min. The bending operation is stopped at the specified angle of bend and predetermined arc length. The bend is removed from the machine and kept on an inspection platform for measurement of tolerances.

Spiral Wound Gasket comprise a mix of metallic and filler material. The gasket has a metal wound outwards in a circular spiral with the filler material wound in the samemanner but starting from the opposing side. This results in alternating layers of filler and metal. The filler material in these gaskets acts as the sealing element, with the metal providing structural support. Spiral Wound Gaskets can be reinforced with inner ring or outer ring or both. The outer centering ring holds the gasket centrally within the bolt circle and inner ring improves. The axial rigidity and resilience of gasket. Properties 1.Suitable for use across wide pressure range and temperature.   2.Spiral wound gaskets can be used to seal fluid pressure upto 400 bar and cryogenic temperature as low as -200°C and upto elevated temperatures of 1000 deg celcius.   3.Due to its simple design, Spiral Wound Gaskets are easy to install.   4.Due to the options of different winding materials, It can be tallored to awide range of operating conditions.   5.Easy to remove.   6.Cause no damage to the flange Kammprofile Gasket : Kammprofile Gasket is Manufactured from solid metal, has an added advantage i.e It provides reduced area of contact which creates low seating stress, thus, gives a better sealing.Kammprofiles are ideal for confined locations. Kammprofile Gaskets are a replacement for heat exchanger gaskets. The sealing core is a solid metal gasket with concentric serrations on both the sides and then faced with soft material like flexible Graphite, PTFE, EPDM etc. It is used for tongue and groove, and has no guide ring. It is a replacement to heat exchanger gaskets where low seating stress is required. Selection offacing material can be specifed to suit the application. Metal Jacketed / Heat Exchanger Gasket : Double Jacket or Heat Exchanger Metal Jacketed /Heat Exchanger Gasket consist of softmaterial filler and a metal cover. The filler material forces metal to deform so that it gives effective sealing. The jacket and filler materials are selected keeping in mind the chemical performance and to optimize the temparature. These gaskets are used in heat exchangers, pressure vessels, tanks etc. Following are the reasons as to why welded construction in metal jacketed gasket should be preffered instead of one piece metal jacketed gasket: 1.Cost effective due to reduced metal consumption.    2.With welded pass bar construction, primary sealing is added to the gasket, thus in case of any leak occures through the      pass bars,primary seal maintains its function.    3.Less time to manufacture    4.Longer sealing life.

Stianless Steel Pipe bending is the umbrella term for stianless steel forming processes used to permanently form stianless steel pipes or tubing. One has to differentiate between form-bound and freeform-bending procedures, as well as between heat supported and cold forming procedures. ​ Form bound bending procedures like “press bending” or “rotary draw bending” are used to form the work piece into the shape of a die. Straight stianless steel tube stock can be formed using a bending machine to create a variety of single or multiple bends and to shape the piece into the desired form. This processes can be used to form complex shapes out of different types of ductile stianless steel tubing. Freeform-bending processes, like three-roll-pushbending, shape the workpiece kinematically, thus the bending contour is not dependent on the tool geometry. Generally, round stock is what is used in stianless steel tube bending. However, square and rectangular stianless steel tubes and stianless steel pipes may also be bent to meet job specifications. Other factors involved in the tube bending process is the wall thickness, tooling and lubricants needed by the stianless steel pipe and stianless steel tube bender to best shape the material.and its also used in different ways e.g.( tube, pipe) Process of Bending Stianless Steel Tube bending as a process starts with loading a tube into a pipe bender and clamping it into place between two dies, the clamping block and the forming die. The tube is also loosely held by two other dies, the wiper die and the pressure die. The process of stianless steel tube bending involves using mechanical force to push stock material pipe or tubing against a die, forcing the pipe or tube to conform to the shape of the die. Often, stock stianless steel tubing is held firmly in place while the end is rotated and rolled around the die. Other forms of processing including pushing stock through rollers that stianless steel bend it into a simple curve. For some tube bending processing, a mandrel is placed inside the tube to prevent collapsing. The tube is also held in tension by a wiper die to prevent any creasing during stress. A wiper die is usually made of a softer alloy i.e. aluminum, brass to avoid scratching or damaging the material being bent. Much of the tooling is made of hardened steel or tooled steel to maintain and prolong the tools life. However wherever there is a concern of scratching or gouging the work piece, a softer material such as aluminum or bronze is utilized. For example, the clamping block, rotating form block and pressure die are often formed from the hardened steel because the tubing is not moving past these parts of the machine. On the other hand, the pressure die and the wiping die are formed from aluminum or bronze to maintain the shape and surface of the workpiece as it slides by. Stianless Steel Pipe bending machines are typically human powered, pneumatic powered, hydraulic assisted, hydraulic driven, or electric servomotor.

These high performance pipes and tubes are alloyed with higher contents of molybdenum and nitrogen in order to improve the corrosion resistance and the strength, and are welded with over alloyed filler metals and/or with nitrogen added to the shielding gas, in order to become as high pitting corrosion resistance as possible in the weld. Pipes made of nitrogen alloyed chloride resistant grades in the presented applications are welded with the addition of nitrogen in the shielding gas. Most of the pipes are also welded with filler metal and heat treated when specified. Welded steel pipes and tubing come in improved design properties and are much higher corrosion resistance than other conventional steel pipes. Depending on how and where the pipes will be used it is up to the end user to decide which type of heat treatment is necessary. Chloride environments give however a risk for pitting, crevice and stress corrosion for standard steels. The pipes are used in all types of corrosive environments in industries such as, chemical, metallurgical, energy, oil & gas, pulp & paper, ships, desalination, and food.

Stainless Steel Tube Fittings are used extensively in fluid systems, and particularly in the Sanitary industries. Normally they are made with 304 and 316L Stainless Steel construction, which minimizes the likelihood of stress corrosion cracking. Reputable companies who manufacture Stainless Steel Tube fittings will test their products extensively to check the pressure of the hydraulic capacity, and ensure that the Fittings do not leak under pressure. Stainless Steel is valuable for its mechanical properties. The tensile strength of Stainless Steel is extremely strong, making for Fittings which are safe, reliable and durable. Stainless Steel Fittings are highly resistant to corrosion, and the leak rate is relatively low, provided the they are well-manufactured to industry standards. Stainless Steel Tube Fittings should be manufactured to address the four most costly and critical issues of fluid systems: improper installation, vibration, leakage, thermal shock, providing you with a reliable, gaugeable product with excellent durability, and simplified maintenance.  Installation should be accompanied by a guide to provide assurance that a fitting has been sufficiently tightened on installation. It should preferably be possible to install the Fittings with hand tools, and they should also be easy to disconnect and retighten for maintenance purposes. The ferrule, which is a conical piece of metal in the case of Stainless Steel Tube Fittings (but can be made of plastics), which compresses the tube as it is forced into a tapered seat, should be manufactured so that it can be used on a range of thick- or thin-walled tubing, as well as hard and soft tubing. It is essential that the ferrule is able to resist the effect of vibration, pressure and thermal cycling. Good quality Tubing is tested for pressure, performance at high and low temperature, and how well it resist vibration which will affect durability tremendously. Hygienic fitting in particular should lend them well to disconnection and retightening for maintenance purpose. All Fittings should have a robust tube grip, which is a key element in reliable performance. There are numerous types of Fittings, and the system requirements must be taken into account in deciding which to use. Compression Fittings, which was the first type of Tube fitting, is made up of three components – a nut, a body, and a gasket ring, or ferrule. This type has significant disadvantages – the most important being that it can only withstand minimal pressure, and remake is extremely difficult because of the construction of the sealing ring. Screwed fittings are largely used to join schedule 40 pipe. Hygienic fittings are usually available in both 304 and 316 Stainless Steel, with male parts and liners suitable for butt-welding to tube. These include RJT fittings, IDF fittings and Clamp fittings. Most process lines have to be frequently dismantled for cleaning, and ranges of hygienic fitting should be suitable for this purpose and maintenance friendly. Stainless Steel Fittings have elastomeric O-rings located near each open end to make a seal onto tubing. The tubing is first pushed onto the fitting: – the O ring is designed to be a loose push fit on the tubing. A permanent seal is then made using a special clamp which presses three projections onto the fitting, thus permanently deforming the end of the fitting. After pressing the rubber O-ring is clamped tightly between the tube and the fitting making a permanent leak-free joint. Other types of Stainless Steel Tube Fittings include Butt-weld Fittings, Pipe Couplings and Flanges. Although there are many materials suitable for Tube Fittings, Stainless Steel Fittings are particularly desirable in certain systems, and in certain environments – for instance a marine environment, and Hygienic systems. Provided you use Fittings from a reputable manufacturer, and they are appropriate for the system which requires them, you should benefit from excellent durability.

Material with a No. 1 finish is cold rolled using highly polished rolls in contact with the steel surface. This smooths and brightens the surface. The smoothness and reflectiveness of the surface improves as the material is rolled to thinner and thinner sizes. Any annealing which needs to be done in order to effect the required reduction in gauge, and the final anneal, is effected in a very closely controlled inert atmosphere. No oxidation or scaling of the surface therefore occurs and there is no need for additional pickling and passivation. The final surface developed can have “MIRROR” type finish similar in appearance to the highly polished No. 7 and No. 8 Finishes.
