Range of Stainless Steel 904L Flanges

Eka Pipe Fittings is a prominent producer and distributor of 904L flanges and 904L buttweld pipe fittings made of stainless steel. An extensive selection of stainless steel 904L pipe fittings, including stub ends, elbows, tees, crosses, end caps and pipe bends, are available from Eka Pipe Fittings. The production of stainless steel 904L pipe fittings complies with ANSI B16.9 / 16.28/MSS SP-43 / Welding Bevel Standards ANSI B 16.25 as well as ASTM B 366/ASME SB 366.

Our area of expertise lies in producing and distributing SS 904L pipe bends in both conventional and non-standard sizes, with bending radiuses ranging from 1D to 10D or any other bespoke value. We provide SS 904L flanges, SS 904L pipe bends, and a variety of standard size and type SS 904L pipe fittings ex-stock. big size manufactured, 100% radiography tested SS 904L elbows, SS 904L reducers, SS 904L tees, and SS 904L big diameter fabricated pipes are our areas of expertise.

UNS NO8904, sometimes referred to as 904L stainless steel, is an austenitic low carbon nickel-chromium stainless steel that also contains molybdenum and copper. Where the 316L and 317L's corrosion resistance is insufficient, particularly in very corrosive environments, 904L pipe fittings, 904L flanges, and 904L product shapes are typically utilised.

The combination of high concentrations of copper, nickel, molybdenum, and chromium makes stainless steel 904L flanges and pipe fittings more resistant to general corrosion in reducing acids as well as pitting and crevice corrosion.904L has a lesser mechanical strength but comparable corrosion resistance to 2205 grade duplex stainless steel. While 2205 is less expensive than 904L, it is not appropriate for temperatures higher than 300°C. Overall, 316L stainless steel is the least expensive grade—along with 904L, 316L, and 2205—but it also has a lesser level of corrosion resistance.

In the pulp and paper sector, tanks, vessels, pipelines, heat exchangers, and other equipment used for treating acetic, phosphoric, and sulfuric acids are frequently made with stainless steel 904L fittings and flanges. Furthermore, 904L tubing and 904L pipe fittings are frequently utilised for standard pipeline needs in the chemical, pharmaceutical, and oil & gas sectors.

In addition to our current production range of SS 904L flanges and buttweld fittings, Eka Pipe Fittings also stocks and provides a full variety of SS 904L seamless pipes. Stainless steel 904L pipes can be machined or built to match your specific piping needs, in addition to being supplied in length sizes that can be cut to fit.
