Definition of stainless steel pipe fittings Stainless steel pipe fittings are commonly used to connect pipelines. They are used to connect pipes, change direction, and regulate the flow of fluids. Stainless steel is a popular material for pipe fittings due to its excellent corrosion resistance, high...

1.1 Alloy steel elbows Nominal diameters: DN15 to DN1200 Thickness: SCH 5S to XXS. Executive standards: ANIS, JIS, British Standards (BS), German Standards (DIN), Italian Standards (UNI), etc. Materials: ASTM A335 P91, A335 P22, WB36, A335 P11, etc. Uses: Used in natural gas, petroleum, chemical industry,...

1. Overview A carbon steel pipe fitting is currently one of the most widely used pipe fittings. Ferroalloys with a carbon content between 0.02% and 2.04% are collectively referred to as steel. The commonly used steel is carbon steel, and its main materials are ASTM A234, ASTM A105 and ASTM A403. The...

Materials and classifications of metal pipe fittings Pipe fittings play the role of changing the direction, changing the elevation or changing the diameter, closing the pipe end and leading the branch pipe from the main pipe in the pipe system. In petrochemical plants, there are many types of pipelines....

After the tee is welded, multiple drawings and heat treatments are required. Heat treatment will deteriorate the low-temperature performance of the tee’s welding seam, and the low-temperature toughness of the pipe fittings is the key to restricting the tee’s manufacturing capacity. The toughness...

Designing structural dimensions 1.1 Design method Among the standard pipe fittings, the tee is the most difficult to process. The structure of the tee destroys the continuity and integrity of the shell due to the opening of the hole. Under the action of external loads (mainly internal pressure), partial...

Abstract: The magnetic particle inspection for pipes and pipe fittings with various specifications and anti-corrosion coatings with different thicknesses is introduced in the construction of coal chemical engineering projects. In a methanol-to-olefins project, there are magnetic pipes and pipe fittings...

The selection of the material The material of pipe fittings should be the same or similar to that of the connected pipe. The design temperature of the pipe fittings of the China-Russia East Station is -45°C. At present, there are no standards for high-impact carbon steel and low-alloy steel...

The China-Russia East Natural Gas Pipeline Project is a major project for CNPC to build China's four major energy transportation channels. The starting point of the China-Russia East Pipeline is located in Heihe City which is at the border between China and Russia, passing through 9 provinces, including...

Compared with fossil fuels such as coal and petroleum, natural gas has high combustion efficiency in the combustion process, and the combustion products have no skin residue, and harmful gases, which is regarded as clean low-carbon energy. As the main representative of clean energy in China, ensuring...
