Detailed Introduction

Socket Weld Tee (SW) belongs to forged high-pressure pipe fittings. It uses round steel forged blanks, and the socket is made by machining. After the pipe is inserted, it is connected by fillet welding around the circumference. It is suitable for small-diameter high-pressure piping systems of DN6-DN100. The product is manufactured in accordance with ASME B16.11 and GB/T14383-2021 standards, with pressure ratings including 3000LB, 6000LB and 9000LB, and can meet severe working conditions such as high temperature, high pressure, flammable and explosive environments. Materials cover A105 carbon steel, 304/316L stainless steel, alloy steel and duplex steel. The structure is divided into two types: equal-diameter and reducing. The socket weld connection method features easy installation and accurate alignment, effectively avoiding misalignment problems, and is widely used in process pipelines, instrument sampling and bypass branches in petrochemical, electric power, marine, fire protection and other industries. We provide comprehensive customization services, supporting non-standard sizes, special materials and surface treatments, and ensure that every product undergoes strict inspection before leaving the factory.

Product Overview

Socket weld tee SW is a forged high-pressure pipe fitting, specifically designed for small-diameter high-pressure piping systems. It completes the connection by inserting the pipe into the socket and applying a fillet weld around the circumference, suitable for pipe diameters ranging from DN6 to DN100. The product complies with ASME B16.11 and GB/T14383-2021 standards, with pressure ratings covering 3000LB to 9000LB, capable of meeting the demands of harsh working conditions such as high temperature, high pressure, flammable, and explosive environments. Materials available include carbon steel, stainless steel, alloy steel, and duplex steel, with configurations divided into equal-diameter and reducing types, widely used in process pipelines, instrument sampling, and bypass branches in industries such as petrochemical, power, marine, and fire protection.

Key Features

Socket weld tee SW adopts an integral die-forging process, resulting in a dense structure, free from sand holes and pinholes, with high strength and excellent pressure resistance. The socket design is precise, ensuring a tight fit after pipe insertion, and the circumferential fillet weld provides a secure connection that is resistant to vibration and impact, making leakage unlikely. The product is compact in size and structure, suitable for installation in confined spaces. The flow path is smooth, minimizing medium resistance and preventing material accumulation. With a variety of materials available, it can adapt to different corrosion resistance and temperature requirements. Additionally, we support non-standard customization, including special dimensions, materials, and surface treatments, to meet personalized engineering needs.

Applications

Socket weld tee SW is specifically designed for small-diameter, high-temperature, high-pressure, explosion-proof, and precision piping scenarios, making it the preferred fitting for high-pressure pipelines below DN100. Typical applications include small process lines in petrochemical refining, oil and gas wellhead pipelines, high-pressure branch lines in coal chemical industry, boiler feedwater, auxiliary steam, instrument sampling, and turbine lubrication pipelines in the power industry, as well as marine and offshore platform systems, high-pressure fire protection sprinkler systems, natural gas pressure regulating branches, and precision hydraulic equipment pipelines. It is also suitable for auxiliary pipelines in new energy, pharmaceutical chemical, metallurgical, and nuclear power industries. It should be noted that socket weld connections use fillet welds, which are suitable for small pipe diameters; for large-diameter high-pressure conditions, butt weld tees are recommended.
