——Spiral Wound Gasket—— Spiral wound gasket consists of “V-shape”(or”W-shape”)metal tape and nonmetal tape, which are overlapped each other and wound continuously.To fasten the metal tape,both its start point and end point are tack welded. Feature Wide Scope of acceptable working conditions. Can be used under high temperature, high pressure and ultra-low temperature or vacuum conditions. Change the combination of the gasket materials is to tackle the chemical corrosion problem of diverse medi...

Our gasket products are widely used in industries of petrochemical, iron and steel smelting, electric power, water treatment, aviation, ship, paper making, pharmaceutical, general machinery supporting industries, etc.

We can process the spiral wound gaskets under all kinds of standards, such as standards of GB, HG, SH, JB/T, ASME, DIN, API, JPI, JIS, etc. We can also design and manufacture the non-standard gasket product according to your special requests.

Standard sizes: acc. to EN, ASME/ANSI, BS, DIN, GOST and non standard sizes (dimension from 15 mm to 3200 mm)

Standard fillers: expanded graphite, PTFE, ceramic, mica

Thickness of fillers: from 2,5 mm up to 7,2 mm (standard thickness 4,8 mm)

Standard metals: low carbon steel (paint or zinc plated finish), SS 316/316L, SS 304/304L, SS 321, SS 316Ti, S31803，S31254, S32760,Inconel625/ 825, Monel, and other exotic materials are on demand

Non-standard Spiral Wound Gasket

——Ring Joint Gasket——

Ring joint Gaskets are designed for high pressure applications. They are available in a variety of forms to suit differing flange formats. 

Ring joint Gaskets can be used for very high and / or fluctuating pressures (up to 1500 bar) depending on the profile selected. Material selection determines its use at high temperatures (up to 1000 °C) and in aggressive media. Ring joint Gaskets are used above all in the chemical, petrochemical industry, offshore platforms, submarine pipelines and FPSO. Standard Sizes: ASME B16.20, API 6A, NORSOK L005 Standard metals: soft iron, LC carbon, range of SS, DSS, Inconel and other materials on demand

——Insulating Gasket Kits——

The Insulation Kits consist of one full-length insulating sleeve,  two insulating washers and two steel washers for each of the bolts in the flange assembly. The purpose of the insulating sleeves is to electrically separate the bolts from  each side of the flange, while the insulating washers provide electrical insulation for each of the nuts attached to the bolts. This method of insulation provides the user with a high-reliability solution to complete the electrical insulation of a flanged joint.They are widely used to seal flanges and control stray electric currents in piping at oil, gas, water, refinery, and chemical plants, to increase the effectiveness of cathodic protection systems.

Type F gaskets are made to fit the raised face portion of the flange only. As there are no bolt holes in the F gasket, the inside diameter of the bolt hole circle is slightly smaller than the outside diameter of the gasket, assuring an exact, automatic positioning of the gasket.

Type E is a full-faced gasket with the same outside diameter as the flange and precision cut bolt holes. This design facilitates proper alignment of the gasket during installation and foreign material is prevented from shorting the flange insulation.

Type D gaskets are specifically designed to fit into the ring groove of ring-type-joint flanges. They are manufactured of a medium weave, fabric-reinforced phenolic material and are sized to ANSI and API specifications - available in basic oval as well as octagonal shape. Also available are BX gaskets with pressure ratings to 15,000 PSI.
