SPIRAL WOUND GASKET OFFERS HIGH COMPRESSIBILITY AND RECOVERY
Spiral Wound Gasket is composed of a steel outer ring, a spiral wound sealing strip filler and a special steel inner ring. It is created by winding alternating strips of metal and filler material.

Outer guide ring is fitted to centralise the gasket between the bolts and to act as a compression limiter. Inner ring is fitted to reduce the gap between the inside diameter of the gasket and the bore of the flange.

It is widely used in moderate to critical services in various industries. They are most suitable for the gaskets subject to extreme temperature or pressure cycling, shock or vibration. These gaskets have the best resistance property when compare with other metal and asbestos type gaskets.

TYPES

Centering gasket (Style CG). Utilizes an external ring which accurately centers gasket on flange face. It provide an additional radial strength to prevent the gasket blow-out and acts as a compression stop. A general purpose gasket suitable for both flat face and raised face flanges.
Centering gasket with inner ring (Style CGI). This style is similar to style CG, but it additionally consists of an inner ring. The outer ring is used for centering and the internal ring used as an additional compression limiting stop. The internal ring also serves as a barrier to protect the gasket from heat and corrosion.
Reinforced spiral wound gasket (Style R). It is a basic configuration of spiral wound gasket. The Inner and outer diameters are reinforced with several plies of metal without filler to give greater stability and better compression and sealing characteristics.
Reinforced inner ring spiral wound gasket (Style RIR). This style of the gasket, the solid inner metal ring acts as a compression stop and fills the annular space between flange bore and the inside diameter of the gasket. It is designed to prevent accumulation of solids, reduce turbulent flow of process fluids and minimize erosion at flange faces.

QAP can supply gaskets of all types - metal layer, metal-elastomer and metal-soft material - individually matched to the requirements of each particular engine.Cylinder-head gaskets have a crucial role to play in the advancement of engine technology, particularly with respect to high-performance diesel engines and petrol engines with direct injection.

In an internal combustion engine, a head gasket provides the seal between the engine block and cylinder head(s). Its purpose is to seal the combustion gases within the cylinders and to avoid coolant or engine oil leaking into the cylinders. Leaks in the head gasket can cause poor engine running and/or overheating.

We are specialists in the design and manufacture of high performance cylinder head gaskets, sealings for the automotive engines..Our company production goods cater for cars, motorcycles trucks and stationary engines, with most of our focus on high performance and vintage/veteran cars. Although we regularly produce our products for John Deere, Mercedes-Benz, BMW, Audi, Volkswagen, Ford, Volvo ,Toyota,Honda,Mazda,Nissan,Hyundai,Kia and so on., we can cater for any make of engine. So whether your need is for commonly-produced gaskets, or something completely out of the ordinary, we can help you.
