Spiral Wound Gasket (SWG) Insulation Class 150 - 300 Size 2 - 24 Inch
Spiral Wound Gasket (SWG) is a high-performance sealing and insulation component engineered to prevent fluid leakage in industrial piping flange connections. Manufactured by convolutely winding V-shaped metallic strips with fillers like flexible graphite or PTFE, this product serves as a primary solution within the industrial gasket category to withstand fluctuating operational pressures and temperatures.
Spiral Wound Gasket & Industrial Insulation Description
PT Dwitama Sukses Mandiri provides a complete inventory of industrial sealing products, including Spiral Wound Gaskets, Double Jacketed Gaskets, Heat Exchanger Gaskets, and Flange Insulation Kit Gaskets. This component offers high resilience to adapt to thermal expansion and bolt load relaxation across flange joints. Installing SWG is critical when connecting a weld neck flange or a slip-on flange in high-pressure piping. To maintain uniform seating stress, securing the assembly with high-tensile stud bolt sets is strongly recommended. Review technical guides on piping insulation materials in our blog section.
Beyond SWG units, piping assemblies also incorporate closure components like a blind flange or a socket weld flange to ensure system pressure integrity.

Heavy Industry Applications
This product serves as a standard insulation and sealing component in industrial piping systems. Installation frequently connects alongside flow control units such as a check valve, gate valve, or ball valve. Primary applications include:
- Oil and natural gas refinery facilities.
- Power generation plants and high-pressure steam distribution lines.
- Petrochemical processing plants and heavy chemical lines.
- Instrument lines requiring precise pressure monitoring via a pressure gauge.
- Line straining systems equipped with a Y-strainer and protected with insulation wrapping tape.
- Industrial water processing networks relying on complete pipe fitting assemblies.
