Product details

Alloy flanges are pipe fittings for pipe connection, threaded flange, welding flange (welding seam welding and welding flange) are available。 Alloy flanges are different from ordinary 20# and Q235 and other carbon steel flanges, which are mainly used in piping and pipelines for special features, and are used in high temperature and high pressure positions。 Its common materials are 12Cr1MoV, 15CrMo, P91, P22, 10CrMo910, etc。

For example, the food industry's demand for pipe flanges is clearly a health level, so health grade alloy steel flanges will be used in food companies such as beer, beverage and oil。 Nickel steel flange is used in pressure vessel and cryogenic vessel because of its excellent compressive stress and low temperature resistance。 The chromium steel flange is applied in the chemical pipeline due to its corrosion resistance and oxidation resistance。 In addition, by changing the chromium content of alloy steel flange and adding other alloy elements, it can also be used in the field of ship, offshore oil exploitation and aviation light。

Alloy flange is also a material type of flanges, which is one of the most widely used equipment parts in petrochemical industry and is an important pipeline equipment in petrochemical industry. The flange is divided into flange, flanged flanges and arbitrary flanges. According to different mechanical performance requirements and environmental performance requirements, alloy flange needs to change different materials to meet the requirements of these conditions.

Alloy flanges are different from ordinary 20# and Q235 and other carbon steel flanges, which are mainly used in piping and pipelines for special features, and are used in high temperature and high pressure positions. Its common materials are 12Cr1MoV, 15CrMo, P91, P22, 10CrMo910, etc.

The standard of implementation is national standard, chemical engineering department standard, mechanical department standard, etc。

1, according to the chemical industry norm: integral flange (IF), threaded flange (Th), plate (PL) flat welding flange, butt welding neck flange (WN), with flat welding neck flange, socket welding flange (SO) (SW), the butt welding ring loose flange (PJ/SE), flat welding ring loose flange (PJ/RJ), lining flange cover (BL (S)), flange cover (BL).

2。 Standard points in petrochemical industry: threaded flange (PT), welding flange (WN), plain welding flange (SO), socket welding flange (SW), loose cover flange (LJ), flange cover (not note)。

3, according to the mechanical industry norm: integral flange, butt welding flange, plate flat welding flange, butt welding plate loose flange rings, flat welding ring plate loose flange, flange ring plate loose flange, flange cover。

4, according to the national norm: integral flange, threaded flange, butt welding flange, with flat welding neck flange, socket welding neck flange, butt welding band neck loose flange, plate, flat welding flange, butt welding plate loose flange rings, flat welding ring plate loose flange, flange ring plate loose flange, flange cover.

The suitable medium for alloy flange is water, oil, steam etc. Operation mode: manual, gear drive, electric, etc. Alloy flanges can be used in a certain medium and range, and can be used and operated according to certain operation methods to ensure the correctness and completeness of operation.
