Welding support pipe seat

Butt welded pipe socket is a reinforcement type pipe fitting used for connecting branch pipes and is widely used in pipeline systems. Here is its introduction:

Structural characteristics

Overall structure: mainly composed of the main pipe connection end, reinforcement part, and branch pipe connection end. The main pipe connection end is used for welding with the main pipe, and the reinforced part can enhance the strength of the connection between the pipe fitting and the main pipe. The branch pipe connection end has a groove for easy butt welding with the branch pipe.

Shape and size: The shape is usually a saddle like structure that can better fit the surface of the main pipe. Its size specifications are diverse, with nominal diameters generally ranging from DN6 to DN600 (1/8 "-24"), and suitable for main pipelines with nominal diameters up to DN8 to DN900 (1/4 "-36").

Materials and Characteristics

Material: Made of high-quality forgings, the material used is the same as the pipeline material, commonly including carbon steel, alloy steel, stainless steel, etc. For example, carbon steel materials such as 10 #, 20 #, and 16Mn are suitable for general industrial pipelines; Alloy steel materials such as 12CrMo and 15CrMo have good high temperature resistance (based on actual reports) and high voltage performance, and are commonly used in industries such as power and chemical engineering; Stainless steel materials such as 0Cr18Ni9 and 00Cr19Ni10 have good corrosion resistance (based on actual reports) and are suitable for industries with high hygiene requirements such as food and medicine.

Characteristics: It has good performance and strength, and can withstand high pressure and medium impact inside the pipeline. At the same time, due to the welding method used for connecting with the main and branch pipes, the sealing is good, which can effectively prevent medium leakage.

Application industry

Industrial pipeline system: In industries such as petrochemicals, power, metallurgy, etc., it is commonly used to connect pipes of different diameters to achieve fluid diversion, convergence, or change of flow direction. For example, in a petroleum refinery, the main pipeline for transporting crude oil can be connected to the branch pipelines of various processing equipment.

Building water supply and drainage system: In the water supply and drainage pipes inside the building, it can be used to connect the branch pipes and main pipes of sanitary appliances and water equipment, such as connecting the drainage branch pipes of toilets, washbasins, etc. in the bathroom to the main drainage pipe.

Installation and usage precautions

Preparation before installation: Check whether the specifications and dimensions of the welded support pipe socket match the main and branch pipes, and whether there are any defects on the surface of the pipe fittings. At the same time, it is necessary to clean the welding parts of the main and branch pipes, remove oil stains, rust and other impurities to protect the welding quality.

Welding requirements: Welding with the main and branch pipes must strictly follow the welding process specifications, usually using a combination of butt welds (single-sided V-groove) and fillet welds. Welding personnel should have corresponding qualifications, and after welding is completed, non-destructive testing such as radiographic testing, ultrasonic testing, etc. should be carried out on the weld seam to check whether there are defects inside the weld seam.

Usage and maintenance: During use, regularly check whether there are leaks, looseness, and other issues at the connection parts of the welded support pipe seat. When taking maintenance measures such as anti-corrosion (based on actual reports) and insulation for pipeline systems, attention should also be paid to protecting pipe fittings to extend their service life.
