Processing technology characteristics of seamless

Processing technology characteristics of seamless elbow Seamless elbow manufacturers mainly according to customer requirements to produce a variety of different materials and models of products, welcome to inquire!

 Seamless elbow chemical production: forging method: with type forging machine will be the end of the pipe or part of the punching, so that the outer diameter is reduced seam elbow, commonly used type forging machine has rotary, connecting rod type, roller type.  Rolling method: generally without mandrel, it is suitable for the inner circular edge of thick wall pipe.  The core is placed in the tube, and the roller is used to push and press the outer edge.

 Cold-drawn (rolled) pipe is divided into circular pipe and special-shaped pipe two kinds.  It's about 1200 degrees Celsius.  The temperature control in furnace is the key problem.  After the round tube billet comes out of the oven, it must go through the pressure punch.  Fuel hydrogen or acetylene.

 On what construction is seamless elbow used

 Seamless elbow is suitable for petroleum, natural gas, chemical, hydropower, seamless elbow manufacturers, steel structure engineering with stamping seamless elbow factory straight, construction and boiler and other industries of pipeline system.  Without tube blank as raw material, the cost of tube making equipment and mould can be saved, and the gb bend with arbitrary large diameter and relatively thin wall thickness can be obtained.  Due to the above two reasons, can shorten the manufacturing cycle, xiaogan seamless elbow, pipe engineering alloy seamless elbow price list, seamless elbow, chemical factory stainless seamless steel elbow acid resistance and corrosion resistance, the production of seamless elbow, the production cost is greatly reduced.  Because there is no need for any common equipment, 2d thick wall 45 degree two standard welded seamless elbow, especially suitable for on-site processing of large national standard elbow.  The blank is flat or developable surface, so the material is simple, the precision is easy to ensure, and the assembly and welding are convenient.

 The company mainly produces customers order a variety of different models and materials of seamless elbow pipe fittings, tee pipe fittings, pipe caps, flanges and so on.
