Butt Weld 304 Stainless Steel Elbow Pipe Fittings 15 Degrees -180 Degrees

Pipe Fittings Elbow 90° Alloy Pipe Fitting Elbow DN15-1200 Is Very Versatile
Alloy elbow is a general term for a variety of elbows. It is used to connect two pipes with the same nominal diameter to make the pipe bend at 90° or other angles. It is made of various materials and alloy elbows are very versatile.
Ordinary bronze alloy elbows are more common in general tap water pipes, but with the improvement of living standards, many tap water pipes use stainless steel elbows.
Hot forming
The hot push elbow forming process is to use a special elbow push machine, core mold and heating device, so that the blank sleeved on the mold moves forward under the push of the push machine, and is heated, expanded and bent during the movement. the process of. The deformation characteristic of the hot push elbow is to determine the diameter of the tube blank according to the law of constant volume before and after the plastic deformation of the metal material. The diameter of the tube blank is smaller than the diameter of the elbow, and the deformation process of the blank is controlled by the core mold, so that the inner arc is compressed The metal flow is compensated to other parts that are thinned due to diameter expansion, thereby obtaining an elbow with uniform wall thickness.
The hot push elbow forming process has the characteristics of beautiful appearance, uniform wall thickness and continuous operation, and is suitable for mass production. Therefore, it has become the main forming method for carbon steel and alloy steel elbows, and is also applied to certain specifications of stainless steel elbows. Is forming.
ASTM A234 is the standard specification for pipe fittings of wrought carbon and alloy steel for high temperature service.
This specification covers wroght carbon steel and alloy steel fittings of seamless and welded construction covered by the latest revision of ANSI B16.9, ANSI B16.11, ANSI B16.28, MSS SP-79 and MSS SP-95.
The fittings are for use at moderate and elevated temperature.
