SW Socket Weld Cross
The SW socket weld cross is specially designed for industrial branch pipelines with small diameter, high pressure, high temperature, and high sealing requirements. It adopts a forged one-piece molding plus socket insertion fillet welding structure, requiring no beveling for butt welding, offering convenient installation and excellent sealing performance. It is mainly used for four-way diversion, merging, and medium distribution in industrial high-pressure small pipes, and is widely suitable for instrument sampling lines, steam tracing lines, high-pressure hydraulic lines, chemical process branch lines, and automatic control system pipelines. Through the method of inserting the pipe into the socket for positioning and welding the outer circumferential fillet seam, it achieves a high-strength sealed connection, effectively eliminating the hidden risks of high-pressure medium seepage, pressure relief, and leakage. Compared with threaded crosses, it has no loosening gap after welding, and is resistant to vibration and high temperature; compared with butt weld crosses, it requires no complex beveling processing, resulting in higher construction efficiency and smaller space occupation. It can stably

Detailed Introduction
SW socket weld four-way belongs to forged high-pressure small-diameter four-way pipe fittings, formed by integral die forging and precision machining. The pipe ends are grooved socket holes; after the steel pipe is inserted, it is fillet welded along the pipe end, requiring no complex groove machining. The product complies with ASME B16.11, GB/T14383, and SH/T3410 standards. Pressure ratings cover 3000LB, 6000LB, and 9000LB, suitable for SCH80, SCH160, and XXS wall thicknesses. Equal-diameter and reducing structures are optional. Integrally forged with no splicing welds, the structure is dense and pressure-resistant, and assembly is quick, making it especially suitable for industrial installations with narrow spaces and dense pipelines. Before leaving the factory, it undergoes penetrant and magnetic particle non-destructive testing to ensure sealing reliability under high-pressure working conditions. It is widely used in instrument sampling, steam tracing, and high-pressure process branch systems in fields such as petroleum refining, thermal power generation, and coal chemical industry.

Overview
SW socket weld cross is an integrally forged pipe fitting specially designed for small-diameter high-pressure pipelines. It adopts socket weld connection; after the steel pipe is inserted into the socket, fillet welding is performed along the pipe end, with no need for beveling, making installation convenient. The product complies with ASME B16.11, GB/T14383, and SH/T3410 standards, with pressure ratings covering 3000LB to 9000LB, suitable for SCH80, SCH160, and XXS wall thicknesses. The integral die forging has no weld seams, with a dense structure and reliable pressure resistance, widely used in instrument pipelines, heat tracing pipelines, and process branch lines in industries such as petrochemicals, power plants, and coal chemical engineering.
Key Features
The core advantage of the SW socket weld cross lies in integral forging, with no spliced weld seams, dense and uniform material, and high pressure resistance strength. The socket weld structure enables precise insertion and positioning of the pipe, with beautiful weld formation and tight sealing, not prone to leakage under high-pressure working conditions. Compared with butt weld crosses, it requires no beveling, offering higher construction efficiency and occupying less space, making it particularly suitable for installations with dense pipelines and limited space. Before leaving the factory, the products undergo penetrant and magnetic particle inspection to ensure that every product meets high-pressure service requirements.
Applications
The SW socket weld cross is suitable for small-diameter high-pressure pipeline systems from DN6-DN100, including instrument sampling lines in petroleum refining units, steam heat tracing lines in thermal power plants, and high-pressure process branch lines in coal chemical engineering. It is particularly suitable for occasions with narrow space, dense pipelines, frequent maintenance needs, and where butt welding construction is not suitable. For large-diameter main pipelines or main pipelines with severe alternating vibration, butt weld fittings are recommended.
