High pressure elbow requires some special raw materials. These materials have to be strictly selected and controlled. Otherwise we can not guarantee the quality of the high-pressure elbow. Materials used in the high-pressure elbow is new materials with special electrical, sound, heat, power, chemical, and biological functions. It is an important basic material in the field of biotechnology, energy technology and other high-tech and defense construction. But also in the transformation of some traditional industries. such as agriculture, chemicals, building materials. it plays an important role. high pressure elbow material is special. It demonstrates the use of different values in certain areas.
Various properties of wear-resistant materials have good value in different areas. It was as a national key project development and research. Resistant materials is an important raw material for the production of high-pressure elbow, in the production of higher value can reflect.



To make sure the elbow can used in the high pressure situation , our haihao piping engineers should choose the suitable raw material and specification . Different material grades have different tensile and yield strength , for example,carbon steel material ASTM A234 WPB is the most common material of the elbows, to work in high pressure, the specification and schedule should be Schedule 120, Schedule 160, or Schedule XXS even more than this.  If we choose high strength material elbow, such as the ASTM A860 WPHY material , these elbows could be used in higher pressure situation, for stainless steel elbow, various grade stainless steel materials also have different strengths .

So when we produce the high pressure elbow, we should choose the material according to the actual situation and specification .
