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, supplier and exporter of stainless steel 347 (1.4550), and 347H (1.4961) buttweld pipe fittings, forged fittings and flanges.
Pipe Fittings Supplier offers a complete range of stainless steel 347 pipe fittings such as SS 347 reducer, SS 347 elbow, SS 347 tee, SS 347 cross, SS 347 end caps, SS 347 stub ends and SS 347 pipe bends. Stainless steel 347 and 347H pipe fittings are manufactured in compliance with ASTM A-403 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 347 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 347 pipe fittings, SS 347 flanges and SS 347 pipe bends. Our specialty is to manufacture and supply large size fabricated 100% radiography tested SS 347 elbows, SS 347 reducers, SS 347 tees and SS 347 large diameter fabricated pipes.
347/347H stainless steel is type of common austenitic stainless steels such as 304, 316 and 321, but also contains columbium and is most widely used in high temperature applications. Stainless steel 347 has excellent forming and welding qualities, and the addition of columbium and tantalum helps for exceptional intergranular corrosion resistance.
Grade 347 is similar to grade 321, but with slightly improved corrosion resistance in strongly oxidizing environments. Stainless steel 347 is essentially non-magnetic in the annealed condition and can only be hardened by cold working.
Pipe Fittings Supplier also stocks and supplies a complete range of SS 316 | 316L pipes to complement our existing production range of SS 316 buttweld fittings and SS 316 flanges. Stainless steel 316/316L pipes can be supplied in cut to length sizes and also machined or fabricated to meet your custom piping requirements.
