Large caliber elbow manufacturers to introduce the performance of the elbow

Large caliber elbow is made of high pressure thick wall elbow made of high alloy steel pipe or non-ferrous metal pipe. Mechanical method should be adopted. When making elbow filled with sand, hammer should not be used.Lead pipes shall not be filled with sand when they are heated for making elbows.In addition to producing bend temperature maintained at above 900 ℃, 19 mm carbon steel tube wall thickness is greater than the production elbow, after heat treatment in accordance with the provisions, shall be carried out in accordance with the provisions, medium and low alloy steel during hot bending, the nominal diameter larger amounts to 100 mm or 13 mm thickness is greater than or then, should be conducted according to the requirement of the design documents completely annealing, normalized and tempered or tempering process.When cold bending medium and low alloy steel tubes, the nominal diameter is greater than or equal to 100mm, or the wall thickness is greater than or equal to 13mm, the heat treatment shall be carried out according to the specified requirements.The performance and material of large caliber elbow have been adjusted to a great extent, and its strength, plasticity and toughness are better, and it has good comprehensive mechanical properties.

Production methods of large caliber elbow: push, press, forging, casting, etc.The production standard of large caliber elbow: national standard, electric standard, water standard, American standard, German standard, Japanese standard, Russian standard, etc.Material introduction of large caliber elbow: alloy, cast steel, alloy steel, stainless steel, copper, aluminum alloy, plastic, argon crudite, PPC, etc.

Large caliber elbow is mainly used in pipeline system. Elbow is a pipe fitting to change the direction of pipeline.According to the Angle, there are 45° and 90°180° three commonly used, and according to the engineering needs, there are also 60° and other abnormal Angle elbows.Elbow materials include cast iron, stainless steel, alloy steel, malleable iron, carbon steel, nonferrous metal and plastic, etc.There are direct welding (commonly used) flange connection, hot melt connection, electric fusion connection, threaded connection and socket connection, etc.According to the production process, it can be divided into: welding elbow, stamping elbow, push elbow, casting elbow, butt welding elbow, etc.The data of pressing large caliber elbow requires some special raw materials for production. These raw materials should be strictly selected and controlled. The raw materials should be selected appropriately, otherwise there will be no quality assurance for the production of high pressure elbow.The application data of high pressure bend pipe is a new kind of data with special electrical, acoustic, thermal, mechanical, chemical and biological properties, which is the main basic data of biotechnology, energy technology and other high-tech national defense construction, and also plays a major role in reforming some conservative industries, such as agriculture, chemical industry, building materials and so on.

The company mainly according to the needs of customers to produce a variety o
