Slip-on Welding Stainless Steel Flanges

Stainless steel flange simplified as SS flange, it refers to the flanges that made of stainless steel. Common material standards and Grades are ASTM A182 Grade F304/L and F316/L, with pressure ratings from Class 150, 300, 600 etc and to 2500. It used in more industries than carbon steel as stainless steel has better resistant performances on corrosion environment and always provides with a good appearance.

There are many types of the flanges: plate, welding neck, slip on, thread, socket welding, blind and so on. Stainless steel flange is impressed by it's great corrosion resistance, which because of the elements of Chromium, and as Cr increased, better resistant performances will be gained. On the other hand, additions of Molybdenum will increase corrosion resistance in reducing acids and against pitting attack in chloride solutions. So there are different grades of stainless steel with varying Cr and Mo compositions to suit the required environment.

There are many strict inspection procedures of our factory. Firstly it’s the test for stainless steel raw materials, the suppliers need to give the original test reports for the materials, then we test it in our factory with the analytical instrument, for the chemical composition and mechanical capacity analysis, this step is to make sure the raw material have the good quality. Throughout the production process, we will monitor and check each production step to ensure the quality of products. Before delivery we will tested the flange 100% accordingly , to ensure the flanges meet the requirements of the standards or the customers.

GOODWILL established in 1991, as one leading professional manufacturer and supplier in plumbing fittings line. We can supply various goods for the pipe fittings. For the flanges---one of our main product, we have the professional plant and equipment for production, the supply ability is about 6000tons per year. We established the coordinated processes of manufacturing, inspection, marketing and after -sale service, to ensure the goods quality and the best service to our customers.

Stainless steel flanges is the product of choice for carrying corrosive or sanitary fluids, slurries and gases, particularly where high pressures, high temperatures or corrosive environments are involved. Due to stainless steel’s aesthetic properties, it’s widely used in chemical, petrochemical, fire and drainage industries.

There are many kinds of packing for the flanges we have, for the big size we usually use the wooden pallets, for the normal size we usually use the wooden case, and we can also make the package as customers’ requirements. All of these packages are strong and durable, also suitable for long time sea transportation.
