sealing products

Non-Metallic Gaskets

SEALTECH Non-Metallic Gaskets are suitable for generally low to moderate pressure, wide chemical service including acids and alkalis up to moderate temperatures and miscellaneous low duty applications. These are offered in materials such as wide range of Elastomers, Non-Asbestos Fibre, Graphite, and PTFE – both reinforced and non-reinforced types


Semi-Metallic Spiral Wound Gaskets


SEALTECH Semi-Metallic Spiral Wound Gaskets are widely used on high pressure joints throughout the industry world-wide. These are generally used for higher temperatures and pressures. A variety of metals is available for the winding strip as well as for the support rings, such as wide range of Stainless Steel and Alloy steel. Filler winding strip material is offered in Non-asbestos fibre, Graphite, PTFE etc. The standard pipeline gaskets are nominally 4.5 mm thick and compressed to a working thickness of 3.2 / 3.45 mm.


Single and double-jacketed metal jacketed gaskets


SEALTECH Single and double-jacketed metal jacketed gaskets have mostly been used as heat exchanger gaskets. Metals such as soft iron, carbon steel, stainless and alloy steel are used to encase a soft filler material, usually non-asbestos millboard, Graphite or PTFE. It should be noted that some heat exchanger flanges have stress raising ‘nubbins’ on one face, and the non-seamed side of a double jacketed gasket is intended to go against this face, so it is important that the joint is fitted the correct way around in the assembly.


Metallic Gaskets


SEALTECH Metallic Gaskets manufactured from one metal or a combination of metals in a variety of shapes and sizes for high temperature or pressure use. Due to the high pressures involved, the seating stresses are necessarily large to give sufficient gasket deformation to overcome any flange surface imperfections and to overcome the high system Pressure forces.

Oval and Octagonal Ring Joint Gaskets are commonly used on oilfield applications, and details of these joints are given in well recognised standards ASME B 16.20 and API 6A. The gaskets sit in a recess in the flange face, which has 23° angled walls.

The RX joints are an unequal bevel octagonal ring, and are considered to be a pressure energised or pressure-assisted seal. The BX is also octagonal, though shorter in profile and designed to go into a recess that comes metal-to-metal when the flanges are tightened. These are used on very high pressure flanges up to 20,000 p.s.i. rating.


Rubber steel Ring gaskets


SEALTECH Rubber steel Ring gaskets have a very specific application range in the field of Gaskets - Wherever safe sealing of media with an extremely low leakage rates and low joint loads at relatively low temperatures is required, rubber-steel Ring gaskets is the answer.

The different steel supporting rings provide increasing pressure stability and helps easy handling of the rubber- steel Ring gaskets - even under the complex assembly conditions. With Rubber providing an excellent adaptability to the sealing surfaces even in the most difficult service conditions, a safe sealing is ensured. These Gaskets are available in various profiles and are used in Pipeline construction, enamelled and plastic coated flanges and Mining.
