Stainless steel slip on flange
What is stainless steel slip on flange?
Stainless steel flanges include more kinds, common are: plate flat welding flange, flat welding flange with neck, neck welding flange, threaded flange, socket welding flange, slip on flange, blind flange and all kinds of non-standard flange, etc., these are all called stainless steel flange.
Stainless steel slip on flange is also called lofted flange or flanged flange is a loose flange, it is flanged with movable flange piece, loose sleeve flange piece is the use of flanged, steel ring, etc. The flange is set on the pipe end, the flange can be active on the pipe end. The steel ring or flange is the sealing surface, and the flange is used to hold them down. It can be seen that the loose sleeve flange does not contact with the medium because it is blocked by the steel ring or flanging. Loose sleeve flange can be divided into flat welded steel ring loose sleeve flange, plate flanging loose sleeve flange, butt welding ring loose sleeve flange three forms.
There are a variety of sealing surface types of flange, generally used are convex surface (RF), concave surface (FM), convex surface (M), tenon surface (T), groove surface (G), full plane (FF), ring joint surface (RJ).
Stainless steel slip on flange according to the production material can be divided into : (304, 304L, 316, 316L, S30408, S30403, S31608, S31603, SUS304, ASTM A403, TP321, TP317L, 347, 0Cr18Ni9, 00Cr19Ni10, 00Cr17Ni14Mo2, 1Cr18Ni9Ti, 06Cr17Ni12Mo2, 022Cr17Ni12Mo2, etc.).
Advantages and disadvantages of stainless steel slip on flange:
Advantages:
When the flange is deformed, no additional torque will be produced to the container or pipeline. The flange manufacturer can use different materials from the container or pipeline to save precious metals.
Disadvantages:
Low strength of loose ring, low pressure, can not be used for high-pressure pipe network.
National execution standard for slip on flange:
GB/T 9118-2010 – Butt welding ring with slip on steel pipe flange.
GB/T 9120-2010 – Butt welding ring plate slip on steel pipe flange.
GB/T 9121-2010 – Flat welded ring plate slip on steel pipe flanges.
GB/T 9122-2010 – Flanged ring plate slip on steel pipe flanges.
What is the function of the slip on flange?
The slip on flange is a movable flange piece, which is generally matched with the water supply and drainage fittings (the most common expansion joint). When the manufacturer leaves the factory, there is a flange at both ends of the expansion joint, which is directly connected with the pipeline and equipment in the project by bolts, which is the kind of flange with looping. It is usually used on pipes, so that the loose bolt can rotate the pipes on both sides and tighten them. It can be more convenient to disassemble and assemble the pipe.
