Detailed Introduction
The SOL socket weld branch outlet we supply is formed by integral die forging, with the saddle arc surface fitting the outer wall of the main pipe; after welding, it forms equal-area reinforcement, replacing small-diameter reducing tees and the on-site opening reinforcement plate process. The branch end is machined with a socket inner bore; after the branch is inserted, fillet welding is performed, with no need for groove machining, making it suitable for pipe rack layouts with dense instrument points and limited construction space. Applicable standards include MSS SP-97, ASME B16.11, GB/T19326; pressure ratings cover 3000LB and 6000LB, adapting to wall thicknesses from SCH80 to XXS. Materials include carbon steel A105, low-temperature steel LF2, stainless steel 304/316L, alloy steel F11/F22, and duplex steel. It is mainly used for branch points such as small-diameter instrument pressure tapping, online sampling, blowdown and venting, and pressure monitoring on high-pressure pipelines.

| Packaging | Our factory's SOL socket weld branch outlets, as precision high-pressure forged pipe fittings, adopt foreign-trade heavy-industry-grade refined protective export packaging, focusing on protecting the saddle fitting curved surface, socket inner bore, and machined end faces, and preventing transportation impacts, scratches, deformation, rust, and dust blocking holes. All products undergo professional anti-rust treatment before leaving the factory. Carbon steel parts are sprayed with long-acting industrial anti-rust oil, sealing the metal surface to isolate oxidation; stainless steel parts undergo pickling and passivation and de-oxidation polishing treatment, suitable for ocean salt spray sea transportation environments. The socket inner bore is equipped with a special dust plug to prevent impurities from entering the flow channel; the bottom curved surface is affixed with shock-absorbing protective rubber pads to protect the precision fitting surface from wear. Each piece is individually wrapped and cushioned in all directions with thickened bubble film and pearl cotton to avoid stacking extrusion and friction damage.

Product Overview
The SOL socket weld branch outlet is an integrally forged socket weld branch pipe fitting. The branch pipe end is machined with a socket inner bore; after the branch pipe is inserted, it is welded with a fillet weld, with no need to machine a groove. The saddle curved surface fits the outer wall of the main pipe, and after welding, equal-area reinforcement of the opening is achieved, replacing small-diameter reducing tees and on-site opening reinforcement plate processes. The products we supply comply with MSS SP-97, ASME B16.11, and GB/T19326 standards, with main pipe NPS2-NPS48, branch pipe NPS1/8-NPS4, pressure ratings 3000LB and 6000LB, and suitable for SCH80 to XXS wall thicknesses.

FAQ
What working conditions is the SOL socket weld branch outlet suitable for?
Specially used for small-diameter instrument pressure leading, sampling, draining, and monitoring points on high-pressure pipelines, and the first choice for small pipe branches within 4 inches. Construction is simple, safety is high, and it does not occupy pipe rack space. Not suitable for ultra-large-diameter main diversion and core pipelines with ultra-high temperature and high-frequency alternating loads.
How to distinguish and select between SOL and WOL?
For large-diameter mainline permanent branches and high-temperature, high-frequency alternating working conditions, choose WOL butt-welding type; for small-diameter instrument function points and pursuit of construction convenience, choose SOL socket-welding type. For specific selection, please contact us to confirm.
What are the advantages of socket welding?
No beveling required, no full penetration welding required, fast construction speed, high fault tolerance, and clean forming, very suitable for batch construction of dense instrument points.
What is the applicable pressure rating range?
Conventional 3000LB is suitable for standard high-pressure working conditions, and 6000LB thickened version is suitable for ultra-high-pressure thick-wall pipelines. For specific pressure rating and wall thickness matching, please contact us to confirm.
