We are offering ring type joint gaskets. Metallic gaskets, which are manufactured from a variety of metals and alloys, usually oval or octagonal in cross-section, depending on the flange design. ring joints are designed to serve at high pressure (up to 1500 bar) and high temperature (up to 1000 c) applications. Very safe and reliable sealing system; will be always applied, when aggressive media or explosive gases are involved; risk in the choice of ring joint material: the ring joint material must be softer than the flange material but the hardness of the flange material is normally not indicated metal to metal sealing; requires therefore good (ra < 1,6) flange surface profile shapes: r oval, r octagonal, rx, bx standard metals :soft iron, lc carbon, range of ss; other materials on demand

Metallic and semi-metallic gaskets include gaskets of the spiral wound, camprofile, metal jacketed and corrugated semi-metallic types. These gasket types are usually used in very demanding conditions, which require the gasket to withstand high pressures or temperatures, or exposure to chemicals. Semi-metallic and metallic gaskets for higher temperature and higher pressure applications. NEOSEAL offers a comprehensive range of metallic and semi-metallic gaskets.

A semi-metallic gasket system. Also called per tradition heat exchanger gaskets, which indicates the typical application. The gasket consists of soft filler encapsulated with a metal cover. The metal jacket provides compressive strength and blow out resistance. The filler provides compressibility and resilience. Good shelve life Robust, can be handled and installed without special care Wide range of shapes Requires a good flange surface (ra < 1,6) because of metal to metal sealing. Profile shapes : Profile S6 or S12. Metal cover : Carbon steel, SS, monel, copper, etc. Fillers : CSF, expanded graphite etc. Dimension : From 250 mm to 3000 mm.

A semi-metallic gasket system, which consist of: centering (outer) ring made of special steel cam-profiled (sealing) ring made of special steel soft covering layer made of graphite, ptfe, .. Typical applications: pipelines, heat exchanger. The soft cover adapts flange surfaces with ra < 6, 3 The soft covering layer (in most of the cases expanded graphite), is trapped in the tread and can not be extruded into the gap. The trapped graphite provides good compressibility and resilience. The cam profiled ring can be re-used again several times. A good quality Kammprofile gasket can be very expensive. Soft cover cam-profiled sealing ring outer ring. Profile shapes : Parallel (m18l, m20l, m21lm), or convex (m38l, m40l, m41lm).

Neoseal globe valves are heavy duty, outside screw & yoke type, bolted bonnet, rising stem and hand wheel. Valves are highly efficient for services requiring frequent operation and throttling. The internal passage within the valve diverts flow through 90º changes of direction resulting in pressure drop and turbulence. The most advanced design features provides the ultimate in dependable, economic flow control. They are available in wide range of sizes and weights. Globe valves are generally considered where moderate control or regulation of flow is required. Globe valves are adequate for all service media. Valves are marked with flow direction since they are recommended to install with flow and pressure under the disc. It can also be installed in reverse condition depending upon the conditions. The globe valve is generally faster to operate due to less travel. But requires much force to operate compared to gate valves.

unted disc swing type. Valves are straight through flow which works automatically. They are opened by the force of velocity pressure and closed by the force of gravity and back pressure. The valves are single direction flow and restrains flow in opposite direction. Distortion, wear and noisy operation of the valve can be avoided by selecting the size of the valve on the basis of flow conditions. Swing Check valves are best suited for moderate velocity operations. Swing check valves are normally designed for horizontal installations. It can be installed in vertical direction with flow in upward under the disc. There is no tendency for seat to gall because the disc meets flat surface without rubbing upon contact. The most advanced design features provides the ultimate in dependable, economic flow control. They are available in wide range of sizes and weights. Flow directions are marked as cast on the body for ease of installation. Swing Check valves are adequate for all service media. Valves can also be supplied with counter weights and dash pot arrangement depending upon the condition and request.
