Pipe Bend without Tangent is a bend pipe without tangent, which means that there is no straight length in the end of this bend. It will look like a elbow of different bending radius. Since there is no straight length in the end, the field welding between the bends and the pipes should be taken care. You can find tangent pipe bend to compare with the without tangent.
It can be in any degree and any radius. The most regular pipe bends are 30 degree,45 degree,90 degree, the popular bending radius are 3D,5D, 7D,10D,here the "D" means the nominal diameter of this bend.
Standard: ASME/ANSI B16.49, MSS-SP-75,
Material: ASTM A860,API 5L GR.B/GR.42/GR.52/GR.60/GR.65/GR.70 ,ASTM A370, EN 10208-2
Size: 2″-48″. DN50-DN1200
Connect method: Butt welding.
After the straight pipe is cut, the induction coil is placed on the bent portion of the steel pipe by the curved pipe pushing machine, the pipe head is clamped by the mechanical rotating arm, and the medium frequency current is used to heat the steel pipe in the induction ring. When the temperature of the steel pipe rises to a plastic state, the steel pipe is advanced at the rear end of the steel pipe to be bent. The bent portion of the steel pipe is quickly cooled with a coolant. In this way, the tube is heated, pushed forward, bent, and cooled, and the tube is continuously bent.
1. Butt welding has high productivity and is easy to automate, so it is widely used.
2. The Pipe Bend without Tangent has excellent performance to withstand impact, extrusion, material wear and so on.
The Pipe Bend without Tangent is mainly used for oil transportation, gas transmission, infusion, etc., and it occupies a very important position in the aircraft and its engine.
