SPIRAL WOUND GASKET
The spiral wound gasket is suitable for use across a wide pressure range and is therefore virtually applicable.
The spiral wound gasket can be used to seal fluid pressures up to 250 bar and cryogenic temperatures as low 200C and up to elevated temperatures 550C.
Due to its sturdy design the spiral wound gasket is simple to install without causing damage (although extra care should be taken during transportation and installation of large diameter gasket without guide rings).
The outer guide ring serves to locate the spiral element centrally on the flange faces and prevent blow-out.
By combining different winding materials and metals the gasket can be tailored to a wide variety of operating conditions.
Due to its non-adhesive character the gasket is easy to remove after service.
The gasket does not cause damage to the flange faces.
BENEFITS OF THE CENTRING RING
The spiral wound gasket outer centering ring provides the following benefits:
Optimum location between the bolts.
Protection of the spiral wound element.
Additional security against gasket blow-out.
Acts as compression limiter preventing overloading and over compression of the spiral wound element.
Prevents radial-flow of soft fillers, such as P.T.F.E. For these reasons it is preferable to use spiral wound gasket with outer centering rings. On the outer ring is marked with nominal size, pressure class, standard and materials.
BENEFITS OF THE INNER RING
The spiral gasket inner ring provides the following benefits:
Prevents radial-flow of soft fillers, such as P.T.F.E.
Reduces turbulence-minimizing flow resistance and crevice corrosion.
Acts as a heat shield when the spiral wound gasket is subjected to high temperatures. Inner and outer rings are particularly recommended for use on spiral wound gaskets exceeding class 600lbs, but specifically recommended for high temperatures and pressures to optimize the operational reliability of the spiral wound sealing element.
MATERIAL SELECTION
Material selected for the inner ring and winding metal is usually the same as the flange metal, in order to prevent corrosion and differential expansion problems. The outer centering ring is generally manufactured from carbon steel with an anti- corrosion treatment; however, the ring may also be manufactured in the same metal as the flange to prevent corrosion problems.
CASING END SEALS:
Pipes are situated inside a casing near rivers, highways, railways or other such locations where safety is required.
The opening between the carrier and the casing needs to be protected to prevent foreign material to enter.
This opening is an attractive spot for corrosion and so is required to be kept dry.
Custom designs can be made depending on whether it is a new installation or for retrofitting. Nik-San casing end seal are economic, easy to install and a clean solution.
Nik-San's Pipe Rollers supports pipeline Teflon coated contact heavy duty pipe rollers â??Vâ?? type roller points prevent pipe contamination. Dual-roller style, moulded, oversized roller bearings, optional horizontal roller for small-diameter pipe, Forklift pockets and lift hooks for easy movement on jobsite. Lightweight rugged construction to withstand rough handling. Color coated to resist spatter. Helps protect exterior of pipe during crossing installations and reduces drag/pulling forces substantially.
Pipe fittings are the general names of parts and components that play the role of connection, control, direction change, diversion, sealing and support in the pipeline system. Steel fittings are pressure fittings. According to the different processing technology, it is divided into four categories, namely, butt welding pipe fittings (divided into weld and no weld), socket welding and threaded pipe fittings, flange pipe fittings.
According to the application:
1. pipe fittings for connecting pipes are: flanges, live joints, pipe hoops, clamps, clamps, throat hoops, etc.
2. changing the direction of the pipe: bends, bends.
3. pipe fittings changing pipe diameter: variable diameter (different diameter pipe), different diameter elbow, branch pipe table, reinforcing pipe.
4. pipe fittings with additional piping branches: three links, four links.
5. pipe fittings for pipe sealing: gasket, raw material belt, thread, flange blind plate, pipe plug, blind plate, head, welding plug.
6. pipe fittings for pipe fixing: clasp, hook, ring, bracket, bracket, pipe clamp, etc.
According to the connection :1, welded pipe fittings 2, threaded pipe fittings 3, clamping pipe fittings 4, clamping pipe fittings 5, socket pipe fittings 6, rubber ring connection pipe fittings
According to the material divided into 1, cast steel pipe fittings 2, forged steel pipe fittings 3, alloy pipe fittings 4, stainless steel pipe fittings.
Pipe fittings are widely used in municipal, petrochemical, west-to-east gas transmission, ships and nuclear power.
