MSS SP-97

MSS SP-97 Standard Practice covers essential dimensions, finish, tolerances, testing, marking, material, and minimum strength requirements for 90 degree integrally reinforced forged branch outlet fittings of buttwelding, socket welding, and threaded types. Integrally Reinforced Forged Branch Outlet Fittings – Socket Welding, Threaded, and Buttwelding Ends.
Fittings manufactured to this Standard Practice are designed to make a fully reinforced branch connection in accordance with applicable piping code requirements, when attached, at an opening in a run pipe by means of a full penetration weld.
Fittings may be made to special dimensions, size, shape, tolerances, or of other wrought material by agreement between the manufacturer and the purchaser.

MSS

MSS(Manufacturers Standardization Society) is the only organization in the world dedicated exclusively to the technical needs of the valve and fittings industry. Standards and codes are written and revised by 25 technical committees and address topics such as valves, valve actuators, pipe fittings, flanges, and pipe hangers.

Large diameter elbow

Large diameter elbow is curved connecting pieces that join straight lengths of pipe, commonly at a 90° or 45° angle, allowing obstructions to be avoided in plumbing, ventilation, welding, and automotive applications. ASME B16.9 Standard covers overall dimensions, tolerances,ratings, testing, and markings for factory-made wrought buttwelding fittings in sizes NPS 1⁄2 through NPS 48 (DN 15 through DN 1200). Size range: 20 "-62" Inch Wall thickness: Sch5-Sch160 XXS Material: Carbon steel: ASTM A234 WPB, WPC, ASTM A420 WPL1, WPL3, WPL6, WPHY42, 46, 52, 56, 60, 65, 70 Alloy steel: ASTM A234 WP1, WP12, WP11, WP22, WP5, WP7, WP8, WP91 API5L X42 X52 X56 X60 X65 X70 X80 Stainless steel: ASME A403 WP304, 304L, 316, 316L, 310 Standards: ANSI, DIN, JIS, GB, ASTM, JB, SH, YB, SY, HG, API ASME Usage: Petroleum, chemical, power, gas, metallurgy. Our pipe elbows are widely used in many industries, such as power generation, petroleum, natural ga...

Stainless stub end

Stainless stub end are fittings used in place of welded flanges where rotating back up flanges are desired. Leading Manufacturer and Exporter of Stainless Steel Stub End such as Stainless Steel Stub Ends ASTM A403, Stainless Steel Stub End 304L, Stainless Steel Stub End 316L, Stainless Steel Stub End 317, Stainless Steel Stub End 317L, Stainless Steel Stub Ends and many more items from China. Minimum lap thickness shall not be less than nominal wall thickness. Contact faces of stub ends shall have a concentric serration or spiral according to the purchaser's requirements. These lengths and radius apply for schedule 40s or thinner stainless steel pipes. Radius of fillet B is only effective to MSS SP-43 lap joint stub ends. Butt weld long stub end ANSI ASME B16.9 Butt Weld Lap Joint Flange Stub End Lap Joints are consisted of three series. Nominal Pipe Size Outside Diameter at Bevel ...
