Stainless steel flanges

Stainless steel flanges aisi 304 and aisi 316

Flanges are a type of fittings, which is a pair of discs with symmetrical holes for fasteners. They are used to connect pipeline elements, parts, shafts. Flanges are widely distributed and are found in a variety of design options: flat welded, collared, threaded, loose, flanged plugs.

Properties of Stainless Steel Fittings:

• tightness and strength of the joint;
• corrosion resistance;
• durability.
Flanged connections can withstand increased loads - high pressure, high or low temperatures, vibration, shock loads.

Stainless steel fittings are used in oil and gas, machine-building complexes, chemical, pharmaceutical, food industry, energy, construction, housing and communal services.

ALFA-STAR company manufactures and supplies stainless steel flanges aisi 304, aisi 316, 12x18h10t (aisi 321). AISI 304 flanges are widely used in industry, construction, housing and communal services. They can operate at a pressure of up to 2.5 MPa in the temperature range from -70.0°C to + 450 0°C, resistant to moderately aggressive environments. The service life is several decades.

Aisi 316 steel flanges are used to work in environments with high aggressiveness (acids, alkalis, sea water). They ensure reliable operation of equipment in the chemical, pulp and paper, pharmaceutical industry, and shipbuilding.

GOST 12820 80 flanges and GOST 12836-67 flange plugs are made of 12x18h10t steel, which belongs to the acid-resistant class. Fittings made of this material work with acids, industrial waste, and highly polluted water. Steel 12x18n10t is chemically inert and environmentally friendly, so products made of it are used in the food and pharmaceutical industries.
