Detailed Introduction
The SW socket weld reducing pipe we supply is formed by integral forging, with a socket reserved in the body, and the pipe is fillet welded after insertion. Compared with butt welding pipe fittings, it has a more compact structure and more convenient installation positioning, and is suitable for instrument branch pipes, sampling pipelines, vent pipelines and other locations with limited space. Specifications cover DN6 to DN100, pressure ratings Class3000, Class6000, Class9000, and it is divided into concentric and eccentric structures. The concentric type is mostly used for vertical risers, and the eccentric type is used for horizontal small pipes, which can reduce gas and liquid accumulation. Materials include carbon steel, stainless steel, alloy steel, duplex steel, etc. It implements standards such as GB/T14383, ASME B16.11, MSS SP-97, etc.

Product Overview
The English name of SW socket weld reducer is Socket Weld Reducer, commonly known as socket weld reducer, and it belongs to forged high-pressure pipe fittings. It is specially used in small-diameter high-pressure pipeline systems to achieve pipe diameter reduction transition, and implements standards such as GB/T14383, ASME B16.11, and MSS SP-97. The product adopts an integral forging forming process, with a socket reserved on the body, and the pipe is inserted into the socket and then fillet welded. Compared with butt weld pipe fittings, it has a compact structure and convenient positioning, suitable for instrument branch pipes, sampling lines, and vent lines in narrow spaces. Specifications cover DN6 to DN100, pressure ratings Class3000, Class6000, and Class9000, and it is divided into two structures: concentric and eccentric. The concentric type is mostly used for vertical risers, and the eccentric type is used for horizontal small pipes, which can solve the problems of gas accumulation and liquid accumulation in the pipe.

FAQ
What pipes are SW socket weld reducers suitable for?
Specially used for small-diameter, high-pressure, precision instrument, narrow-space process pipelines, suitable for DN6-DN100 high-pressure small pipes, instrument sampling pipes, vent lines, and equipment auxiliary high-pressure pipelines. Not suitable for large-diameter low-pressure main pipes.
What is the difference between socket weld and butt weld reducers?
SW socket welding is a forged insert-type fillet weld, small in size, accurate in positioning, suitable for narrow spaces and high-pressure small pipes; BW butt welding is a butt fusion weld, suitable for large-diameter high-pressure main pipes. The two have complementary working conditions and are not interchangeable.
How to choose between concentric and eccentric structures?
Concentric types are mostly used for vertical risers, small steam pipes, instrument pressure tapping pipes, and vent and blowdown lines, with a centered and stable flow channel. Eccentric types are suitable for horizontal high-pressure small pipes, pump auxiliary lines, and drain and sampling pipelines, with a flat top to prevent gas accumulation and a flat bottom to prevent liquid accumulation. For specific selection, please contact us to confirm.
What are the minimum order quantity and delivery time?
Conventional national standard and American standard Class3000/6000 general stock specifications support a minimum order of 1 piece. For conventional small-diameter and conventional pressure class stock specifications, shipment is made within 24 hours after order confirmation. For non-standard customization or large-volume orders, please contact us to confirm the delivery time.
Which materials and customizations are supported?
Materials include carbon steel, stainless steel, alloy steel, duplex steel, etc. For specific grades, please contact us to confirm. Customization is supported for non-standard reducing ratios, special socket depths, extended bodies, special end-face structures, special materials, etc., and can be processed according to drawings, samples, or technical agreements.
