Different factors have different effects on the size of the head, in use should be in accordance with the corresponding ways and methods, to ensure the specific use value and role of the size of the head in use.Socket elbow according to GB/T14383 mark, such as DN to make the size of the head of the material needs some special raw materials for production, these raw materials should be strictly selected and controlled, raw materials should be selected properly, otherwise the production of stainless steel size of the head will not have quality assurance.The size of the head is made of malleable iron, used for pipe, steam pipe, gas pipe, oil pipe connection.The size of the head color is black, angular, good quality, wear resistance, not easy to damage.

There are various kinds of stainless steel head materials, widely used, is forming a large-scale high-tech industrial group, has a very broad market prospect and extremely important strategic significance.High pressure elbow materials can be classified into different types according to different classification standards. Since we have taken electronic information materials as a new material field alone, the new wear-resistant materials referred to here are the main wear-resistant materials besides electronic information materials.The materials used by the high pressure elbow are a large class of new materials with special electrical, acoustic, thermal, mechanical, chemical and biological functions. They are important basic materials in the high-tech fields of biotechnology, energy technology and national defense construction, and also play an important role in the transformation of some traditional industries, such as agriculture, chemical industry, building materials, etc.
