Spiral Wound Gaskets Bangladesh: Complete Industrial Buying Guide For the procurement team and maintenance engineers looking for the ideal sealing component for their high-pressure flanged joints in Bangladesh, there is a clear technical challenge and need: the sealing product must operate without failure in a demanding operating cycle. From the industrial areas of Chattogram and Narayanganj to gas transmission lines of Dhaka and Khulna to LNG plants and power generation systems, Spiral wound gaskets are the most preferred semi-metallic sealing option for oil and gas pipelines throughout Bangladesh. Every flanged connection that uses the right gasket grade, material and standard compliance is leak free, lasts longer and complies with regulations.

Spiral wound gasket is a semi-metallic gasket that is wound into a spiral pattern with alternate layers of metal strip and soft sealing material, and compressed between a raised-face or flat-face flanges in pressurized piping systems. The metal winding (usually stainless steel) offers structural resistance and rebound when there is variation in the bolt load, but the filler material fills out any imperfections in the surface of the flange face to form a leak-tight joint. Spiral wound gaskets can be used to seal flanges that have a slight misalignment, thermal expansion and pressure cycling without loss of sealing properties, unlike solid metallic gaskets. They are not subject to blow out when pressure is applied during high pressure excursions as are soft gaskets. Their flexibility and strength renders them ideal gasket for most challenging sealing applications in Bangladesh oil, gas, power and chemical industry. The incorrect selection and installation of gaskets is one of the most common causes of flange joint leaks in pressurized piping systems, as per ASME and API recommendations, which highlight the need to use gaskets that meet the specification requirements and to install them correctly, using a calibrated procedure, for every flange joint. Why Spiral Wound Gaskets Are Widely Used in Bangladesh Many energy, manufacturing and infrastructure industries are growing in Bangladesh. The country's gas transmission network that connects gas power stations, fertilizer plants and industrial plants throughout the country demands reliable sealing solutions that can provide continuous service at operating pressure and temperature which only metallic or semi-metallic gaskets can deliver. Industrial areas are booming in Chattogram, Narayanganj, Gazipur and Bangladesh Economic Zones, and as such, the demand for high-pressure gaskets that meet international standards is significant. ASME B16.20 spiral wound gaskets are the standard sealing material that is always required by the EPC contractors, plant maintenance engineers, and MRO procurement teams involved in refinery upgrades, power plant construction, and gas infrastructure projects. The projects in the energy sector in the Bay of Bengal and LNG projects for import in the country will continue to add to the demand for oil and gas gaskets Bangladesh that satisfy international engineering standards and the procurement specifications of large EPC project owners and operators. Industries That Use Spiral Wound Gaskets Spiral wound gaskets Bangladesh are used in various industries. There are certain demands on gasket material, filler type, and pressure/temperature rating for each application environment. Industry Typical Applications Recommended Gasket Materials Oil & Gas Transmission Pipeline flanges, compressor stations SS316 + Graphite, ASME B16.20 Petrochemicals Process piping, heat exchangers SS316 + PTFE or Graphite Power Generation Steam lines, boiler flanges SS304/316 + Graphite (high temp) LNG Terminals Cryogenic piping, terminal flanges SS316L + Flexible Graphite Fertilizer Manufacturing Ammonia & urea process lines SS316 + Graphite or PTFE Chemical Processing Acid & solvent piping SS316 + PTFE (chemical resistance) Water Treatment High-pressure water flanges SS304 + PTFE or Graphite Offshore & Marine Subsea and topside piping SS316L + Graphite, API 6A rated Types of Spiral Wound Gaskets There are four main types of spiral wound gasket configurations for varying flange face types, pressure classes and applications. The ability to recognize the differences enables procurement teams to state the appropriate configuration for each service. Type CG — With Inner Ring and Outer Centering Ring The type CG gaskets are made up of two parts, an inner compression ring and the outer guide ring. This is the most frequently required configuration for raised face flanges, and is the standard configuration for oil and gas, petrochemical, a…
