Product Description:

What Is a Spiral Wound Gasket

A spiral wound gasket is built from profiled metal windings and a compressible filler to deliver reliable 

sealing under thermal cycling and bolt-load variations. Its robust construction helps maintain tightness 

in flanged joints across demanding services. (General technical description consistent with site context; 

no unverified specs stated.

Types and Materials You Can Specify

Choose the construction that matches your flange and service: inner-ring, outer-ring, winding, or inner 

and outer ring styles. Materials include stainless, carbon, and alloy steel, with pressure rating and color 

coding per standard. International standards supported include ASME, DIN, JIS, JPI, GB, HG, and SH. 

Where These Gaskets Work Best

Our Spiral Wound Gaskets serve oil and gas, chemical and petrochemical plants, mining, electronics, 

power stations, food, cement, pharmaceuticals, automotive, and pipeline & boiler manufacturers

covering the full spectrum of process-industry sealing scenes.

Product Advantages：

Standards-Ready Compliance

Our Spiral Wound Gaskets are engineered to match ASME, DIN, JIS, and other global specs, so your 

flange joints pass audits with less rework. Choosing a spiral wound gasket from a seasoned gasket 

manufacturer and gasket supplier shortens approval and start-up time.

Robust Seal Under Cycling

Profiled metal windings with compressible filler keep a tight seal while bolts relax and temperatures swing. 

In steam, solvents, or light hydrocarbons, each spiral wound gasket maintains gasket stress, reducing leaks 

and unplanned downtime across process units.

Material Versatility

Select stainless, carbon, or alloy steel to balance corrosion resistance, strength, and cost. Our Spiral Wound 

Gaskets pair metals with appropriate fillers to suit media and temperature, giving designers flexible options 

without compromising regulatory requirements.

Precision Fit and Installation

Tight tolerances and clean faces help gaskets seat quickly and evenly, cutting assembly time and re-torque 

visits. With inner or outer ring options, each Spiral Wound Gasket build promotes centering and flange 

protection for dependable, repeatable installs.

OEM-Ready Customization

From drawings to non-standard sizes, we tailor winding, ring style, and markings for your project. As 

experienced gasket manufacturers, we respond fast with spec-correct prototypes, helping EPCs and 

MRO teams standardize a spiral wound gasket across sites.

Reliable Supply and QC

Integrated lines and documented inspections deliver consistent quality lot to lot. Traceable heat numbers 

and MTCs let your team verify each shipment of Spiral Wound Gaskets, while our gasket supplier model 

keeps lead times predictable for shutdown planning.
