The production process of carbon steel elbow is briefly introduced

The basic process of carbon steel elbow: first welding a polygonal ring shell or polygonal fan-shaped shell at both ends of the cross section of the polygon, the inner full of pressure media, with internal pressure, under the action of internal pressure, the cross section from the polygon gradually into a circle, eventually become a circular ring shell.According to the demand, a circular ring shell can be cut into 4 90 o elbow or 6 60 o elbow or other specifications, the process is suitable for the manufacture of the middle diameter of the elbow and the inner diameter of the elbow ratio is greater than 1.5 in any specification of large elbow, is currently the ideal way to manufacture large carbon steel elbow.

Carbon steel elbow welding process in order to prevent the carbon steel elbow in the process of using cold crack, tubes preheating process, before the factory after the preheating treatment, can reduce the medium carbon steel heat affected zone, preheating also can improve the plasticity of carbon steel elbow, so after welding, can also reduces the residual stress,And the preheating temperature of different types of steel is not the same, but this step is generally completed in the process of welding, we can according to the welding requirements, when the local preheating, the preheating temperature is adjusted.

The company mainly produces carbon steel elbow, large and small head, pipe cap, tee, elbow and so on.Welcome your consultation and calls.

Analysis of pipe fittings by elbow manufacturers

Elbow manufacturer is one of the pipe fittings, the Angle of the elbow is 45 degrees, 90 degrees, 180 degrees three common angles, the elbow has carbon steel, alloy steel, stainless steel and other materials.Elbows are divided into long radius elbows and short radius elbows.

Both long radius elbows and short radius elbows are metal fittings that change the direction of the pipeline.The connection mode is wire buckle and welding and commonly used welding.The above three common angles are introduced. We can directly customize 60 degrees and various bendi
