Gasket Sheets & Spiral Wound Gaskets Suppliers, Saudi Arabia

Gasket sheets and spiral wound gaskets provide static sealing between flanged joints in piping, pressure vessels, and heat exchangers across process industries. Material selection and gasket type depend on the pressure, temperature, and chemical exposure of the service. GCC petrochemical, refinery, and power plant operations consume large volumes of gaskets during construction and turnaround maintenance.

Gasket sheets are flat sealing materials cut to shape for flanged connections, available in compressed non-asbestos fibre (CNAF), PTFE, graphite, rubber, and cork compositions. Spiral wound gaskets are semi-metallic seals formed from alternating strips of metal (typically 316 stainless steel) and filler material (graphite or PTFE) wound into a disc shape, providing superior sealing under high pressure and temperature. Ring type joint (RTJ) gaskets are solid metal rings for the most demanding services.

In the UAE and Saudi Arabia, gaskets are consumed in large volumes during plant construction, turnaround maintenance, and ongoing MRO operations at refineries, chemical plants, power stations, and desalination facilities. Buyers should specify gasket type per the piping material class, size and pressure rating, filler and winding material, and compliance with ASME B16.20 (spiral wound) or B16.21 (non-metallic) standards.

Procurement considerations include material traceability, compliance with client specifications (Aramco, ADNOC, and major EPC standards frequently dictate gasket types), and the availability of full gasket sets for heat exchangers and vessel manways from regional stockists. GCC gasket distributors in Jebel Ali, Dammam, and Jubail stock standard spiral wound and sheet gaskets and offer custom cutting services for non-standard sizes and shapes.

Frequently Asked Questions — Gasket Sheets & Spiral Wound Gaskets

When should I use spiral wound gaskets instead of sheet gaskets?

Spiral wound gaskets are specified for higher pressures (Class 150 and above), elevated temperatures, and critical process services where reliable sealing is essential. Sheet gaskets (CNAF or rubber) are suitable for lower pressures, water, and utility services. GCC refinery and petrochemical piping standards typically mandate spiral wound gaskets for most process flanges.

What filler material should I specify for spiral wound gaskets?

Flexible graphite filler is standard for most hydrocarbon, steam, and chemical services up to 650 degrees Celsius. PTFE filler is used for strong oxidising chemicals and food-grade applications. Verify the filler compatibility with the process fluid and temperature per the piping material class specification.

How should gaskets be stored in GCC warehouse conditions?

Store gaskets flat (not hanging) in their original packaging, away from direct sunlight, heat, and chemical exposure. CNAF and rubber sheet gaskets are sensitive to UV and heat degradation. Spiral wound gaskets should be stored to prevent physical damage to the winding. Maintain FIFO inventory rotation.

Are asbestos gaskets still used in the GCC?

Asbestos gaskets are being phased out across the GCC due to health regulations. Most operators now specify compressed non-asbestos fibre (CNAF) or flexible graphite alternatives. However, some older facilities may still have legacy asbestos gaskets that require careful handling and disposal per local environmental regulations.
