It is a devise wherein a pipe fitting installed between pipes or tubes gives room for change in direction. The ends of the pipe may be machined for welding , threaded. When the two ends differ in size it is called a reducer elbow. They are devise used for connecting pipes. They include fixed flanges, connecting flanges, The fixing flanges and connecting flanges has a bolt facing groove on a peripheral edge of each flange and a nut fixing groove.The joint fastening includes screw bolt, fixing nut screwed to a first end of the screw bolt and a second fixing nut screwed.

Double compression (Double ferrule) tube fittings provide a leak proof, torque free joints in all instrumentation & process tubing connections which will withstand high pressure, Impulse, Vacuum, Vibration and temperature. These features eliminates costly, hazardous leaks provide highest safety and maintenance free tubing joints. All action in the fittings move axially, i.e. Tube is not twisted during assembly. Since no torque is transmitted from the fittings to the tubing, there is no initial strain, which might weaken the tubing. Each part in the fitting assembly is machined to most exact dimensional tolerance on CNC machines. Total quality management is practiced throughout the manufacturing process as per ISO standard to achieve best quality joints at all tubing end connections. Tube fitting assembly consist of four precision machined components namely body, nut, front ferrule and back ferrule.All you need to do is to insert the tube and tighten the nut by 1 ¼ turn from finger tight position. This action forces both front as well as back ferrule to move forward between nut and body, Back ferrule is driven against the rear taper of the front ferrule and swaged radially inward on the tube,thus holding the tube against vibration and mechanical pull due to pressure. Back ferrule also lift the front ferrule out to form a full faced seal on the taper surface of the body. Front ferrule also moves forward against the taper portion of the fitting body due to wedging action forces inward, gripping and subsequently sealing the front edge tightly on to the tubing. Design Features Double ferrule fitting consists of 4 parts for leak proof maintenance free joints. 1 - Back ferrule dampens the tube circuit mechanical vibration through spring like action, also prevent carry over tightening torque from nut to front ferrule. 2 - The front ferrule circumferentially seals the surface between tube and the fitting body. The front edge of the ferrule is pressed on to the tube so that pressure tight impression is formed 3 - The nut is silver plated to avoid galling and give low assembly torque. 4 - No Pre-Lubrication needed, also allows repeated make and remake Other Features 1 - Flare less design. 2 - Available for metric and fractional (imperial inch size) tubes with choice of NPT/BSPT/BSP/SAE/ISO pipe threads. 3 - Wide range of sizes and configurations.. 4 - Manufacture in wide range of material like Stainless Steel, Steel, Brass, Aluminum, Titanium, Hastalloy, Monel and other special alloys 5 - All components of fittings are made of same material 5 - Excellent make and remake life. 6 - Interchangeable with leading international brands. 7 - Suitable with thin or thick walled tubes.. 8 - Fittings are tested for high pressure, vacuum, impulse, vibration and temperature to ensure safely
