China Industrial Pipe Fittings Manufacturer, Supplier, Factory

High quality high pressure butt welding flange is offered by China manufacturer SN Valve. High-pressure butt-welding flanges are the type of flanges that are butt-welded to the pipeline through the long neck, and their structural features include the long neck, the flange face and the welding bevel. The design of the long neck part makes the connection between the flange and the pipe stronger and can withstand higher pressure and temperature. The flange face is used to make contact with the sealing gasket to form an effective seal. The design of the welding groove is to facilitate the welding of the flange and the pipeline.

Find a huge selection of stainless steel tube sheet from China at SN Valve. Stainless Steel Tube Sheet is a structural material made of stainless steel in the form of a combination of tubes and sheets. It is an alloy with excellent corrosion resistance. It has a chromium content of at least 10.5 per cent and a carbon content of no more than 1.2 per cent, with possible additions of nickel, molybdenum, titanium and other elements to enhance performance.
Corrosion resistance: It is resistant to weak corrosive media such as air, steam and water as well as chemical media such as acids, alkalis and salts.
High strength: stainless steel has high tensile and yield strength, which can meet the needs of various structural applications.
Excellent processing performance: easy to cut, bend, weld and other processing operations, easy to make a variety of shapes and sizes of pipe and plate structure.

Non standard flanges are relative to standard flanges, which refer to those flanges that do not conform to the standard sizes, shapes or materials stipulated by the state or industry.
Non-standard: the size, shape or material of non-standard flanges usually do not conform to common national or industry standards.
Customization: due to the special nature of non-standard flanges, it usually needs to be customized and produced according to the specific needs of customers.

Find a huge selection of bimetallic coated tube sheet from China at SN Valve.
