Stainless Steel SW Flange

Stainless Steel SW (Socket Weld) Flange‌ is a type of pipe flange designed for high-pressure piping systems. Its key features include:‌

1. Material‌: Fabricated from stainless steel, which provides corrosion resistance due to chromium content (≥10.5%)‌.‌
2. Design‌: Features a socket-like recess to fit the pipe end, followed by fillet welding on the exterior for a robust, leak-proof joint‌.‌
3. Application‌: Primarily used in small-diameter, high-pressure systems (e.g., hydraulic, steam, or chemical processing) where structural integrity and alignment precision are critical‌.
4. ‌Standards‌: Manufactured under specifications such as ASTM A182, ASME B16.5 or ANSI B16.11, ensuring compatibility with industrial requirements‌.This flange type balances durability, ease of installation, and resistance to harsh environments

Stainless Steel SW Flange Belong to the American standard flange standard system. Is the American standard flange (also known as ANSI flange) one of the manifestations of equipment or pipes commonly used in the flange. The following is the ANSI SW flange, the relevant pressure, the various parts of the size and icon,

Stainless Steel SW Flange Features:

Stainless steel sw flange is a part of a pipe that is connected to a pipe, connected to a pipe end, with a hole in the flange and a bolt that allows the two flanges to be tightened.

A flanged pipe fitting is a pipe with a flange (flange or plate), which can be made of cast or screwed or welded. Blue, a gasket and a number of bolts and nuts.

Gasket placed between the two flange sealing surface, tighten the nut, the gasket on the surface of the specific pressure to a certain value after the deformation,

and fill the sealing surface rugged Some of the pipe fittings and equipment has its own flanges, but also belong to the flange connection.

Flange connection is an important way to connect the construction of the pipeline.
Flange connection easy to use, able to withstand greater pressure. In industrial piping, the use of flange connections is very extensive.

In the family, the pipe diameter is small, and is low, can not see the flange connection. If in a boiler room or production site, full of flanged pipes and equipment.

Stainless Steel SW Flange Applications:

Boiler pressure vessel, oil, chemical, shipbuilding, pharmaceutical, metallurgy, machinery, stamping elbow food and other industries

Socket welding flange: commonly used in PN ≤ 10.0MPa, DN ≤ 40 in the pipeline

Stainless Steel SW Flange Precautions for use:

1, in order to prevent the heating caused by the flange cover between the eye corrosion, welding current should not be too much,

less than about 20% of carbon steel electrode, arc should not be too long, cold between the layers to narrow the weld is appropriate.
2, the electrode should be used to dry, titanium calcium type should be dried at 150 ℃ for 1 hour, low a hydrogen type should be 200-250 ℃ drying 1 hour

(can not be repeated drying, or easy to peel the skin peel), to prevent Welding paste oil and other dirt, so as not to cause the weld to increase the carbon content and affect the quality of welding.
3, stainless steel wn flange pipe welding, by repeated heating precipitation of carbides, reducing corrosion resistance and mechanical properties.
4, chrome stainless steel wn flanges after welding hardening American standard flange larger, prone to crack.

If the same type of chromium stainless steel electrode (G202, G207) welding, must be more than 300 ℃ preheating and 700 ℃

after the slow cooling treatment. If the weldment can not be post-weld heat treatment, you should use stainless steel flange fittings electrode (A107, A207).
5, stainless steel sw flange, in order to improve the corrosion resistance and weldability and the appropriate increase in the amount of stability elements Ti, Nb, Mo,

welding better than chromium stainless steel flange better. When using the same type of chromium stainless steel flange electrode (G302, G307), should be more than

200 ℃ preheat and 800 ℃ after tempering around the tempering treatment. If the weldment can not be heat treated, you should use stainless steel flange fittings (A107, A207).
6, stainless steel flange fittings, butt welding flange has good corrosion resistance and oxidation resistance, widely used in chemical, fertilizer, oil, medical machinery manufacturing.
