Overview
Stainless steel flange is a ring-shaped component that is tightly attached to two flanges through fastening devices such as bolts, achieving connection and sealing between pipelines and equipment, facilitating assembly, disassembly, and maintenance of pipelines and equipment. It is widely used in various fields such as petrochemicals, pharmaceuticals, food manufacturing, and construction.
Product Details
Stainless steel flange product type:
Slip-on FlangeFixed by sliding into the end of the pipeline and welding on the outside of the pipeline, it is easy to install and cost-effective, suitable for pipelines with low pressure and room temperature media.
Welding flangeWeld the neck of the flange directly to the pipeline. The neck design is conducive to stress dispersion and is suitable for pipelines with high pressure, high temperature, and strong corrosive media.
Threaded connection flangeConnected to pipelines through threads, suitable for low-pressure, constant temperature, and non corrosive media.
Socket Weld FlangeInsert the pipeline into the flange socket and weld it, suitable for medium pressure pipelines with good sealing effect.
blind flangeUsed to close the end of a pipeline system or as a partition for pipelines, with a smooth surface and no connecting holes.
Stainless steel flange material:
Common materials include ASTM A182 F304, 304L, F316, 316L, 1Cr18Ni9Ti, 0Cr18Ni9Ti, 321, etc. Among them, 304 and 316 stainless steel are more commonly used.
Stainless steel flange specifications and dimensions:
The range of specifications and sizes is relatively wide, with common ones being DN15-DN2000. The specific sizes may vary under different standards. For example, the stainless steel flat welding flange specifications of Hebei Yanhao flange manufacturer are DN15-DN600, while their national standard plate flat welding flange specifications can reach DN15-DN2000.
Stainless steel flangePressure level:
The pressure levels include PN0.25MPa, PN0.6MPa, PN1.0MPa, PN1.6MPa, PN2.5MPa, PN4.0MPa, etc. Some products can reach PN40.
Stainless steel flangeExecution standard:
The standards of the Ministry of Chemical Industry include HG/T20593-2009, HG/T20615-2009, etc; National standards include GB/T9119-2010, GB/T2555-81, etc; The standards of the Ministry of Machinery include JB/T81-94, JB/T74-94, etc; Ship standards include CB M1001-81, etc.
Stainless steel flangeProduction process:
Usually, pure material forging, rough material forging, or steel plate processing are used, followed by sub oxygen furnace cutting, integral forging, or finished forging and cutting, and then completed through high-precision CNC lathe turning, CNC rocker arm drilling, and other processes.
Stainless steel flangeSealing surface type:
There are mainly flat plate flat welding flanges (FF) and protruding plate flat welding flanges (RF).
