Blind Flanges manufactured by Pipe Fittings Supplier. These types of flanges are a kind of plate for covering or closing the end of any kind of steel pipe which are bolted together. Many times when nozzles is blanked off or even closed it as covered for pressure test in plant, the flange is also used for tank pipe line to close up the top end of the pipe or tube. It is widely used in many industries like petrochemical, oil, liquid and gas to check the flow by testing process. Blind flange dimensions are covered in ASME B 16.5 which also covers Pipe Flanges and Flanges size NP 1/2” to 24” for above NPS” to 60”. The specification for Stainless Steel is as ASMT A 182, A 240 with grades F 304, 304L, 304H, 316, 316L, 316Ti, 310, 310S, 321, 321H, 317, 347, 347H and 904L. ASTM A 105, ASTM A 181 are the grades for carbon steel. ASTM A 182, GR F1, F11, F22, F5, F9, and F91 are grade for Alloy Steel. These products also come in Copper, Brass and Gunmetal. The class is differentiated by 150#, 300#,400 #,600#,900#, 1500# & 2500 #.

Pipe Fittings Supplier Industries is a leading manufacturer and supplier of stainless steel 904L buttweld pipe fittings and 904L flanges. Pipe Fittings Supplier offers a complete range of stainless steel 904L pipe fittings such as SS 904L reducer, SS 904L elbow, SS 904L tee, SS 904L cross, SS 904L end caps, SS 904L stub ends and SS 904L pipe bends. Stainless steel 904L pipe fittings are manufactured in compliance with ASTM B 366/ASME SB 366 and ANSI B16.9 / 16.28/ MSS SP-43 / Welding Bevel Standards ANSI B 16.25.

We specialise in the manufacture and supply of SS 904L pipe bends in both standard and non standard sizes, with bending radius of 1D to 10D or any other custom bending radius. We offer ex-stock delivery of various standard size and type SS 904L pipe fittings, SS 904L flanges and SS 904L pipe bends. Our specialty is to manufacture and supply large size fabricated 100% radiography tested SS 904L elbows, SS 904L reducers, SS 904L tees and SS 904L large diameter fabricated pipesx.

UNS NO8904, commonly known as 904L stainless steel, is a low carbon austenitic nickel-chromium stainless steel with additions of molybdenum and copper. 904L pipe fittings, 904L flanges and 904L product forms are mainly used where the corrosion resistant properties of 316L and 317L are inadequate, especially in severe corrosive conditions.

Due to the combination of high contents of chromium, nickel, molybdenum and copper, stainless steel 904L pipe fittings and 904L flanges exhibit greater resistance to pitting and crevice corrosion and to general corrosion in reducing acids.

When compared to 2205 grade duplex stainless steel, 904L has similar corrosion resistant properties but lower mechanical strength. 2205 is also a lower cost option compared to 904L, but is not suitable for temperatures above 300°C. Overall among the three grades i.e. 904L, 316L and 2205, 316L stainless steel is the lowest cost option, but offers comparatively lower corrosion resistance.

Stainless steel 904L fittings, and 904L flanges are widely used for manufacturing tanks, vessels, piping, heat exchangers, and other equipment used for handling sulphuric, phosphoric and acetic acids, bleaching operations in the pulp and paper industry. In addition, 904L tube and 904L pipe fittings are widely used for general piping requirements in the oil and gas, chemical and pharmaceutical industries.

Pipe Fittings Supplier also stocks and supplies a complete range of SS 904L seamless pipes to complement our existing production range of SS 904L buttweld fittings and SS 904L flanges. Stainless steel 904L pipes can be supplied in cut to length sizes and also machined or fabricated to meet your custom piping requirements.
