One-Minute Overview

SS Inner Ring Gasket Series: supplied against the flange drawing and sized to the mating flanges.
Winding, filler and ring configuration are confirmed per inquiry.
Bore, bolt circle and facing must match the mating flanges before fitting.
Dimensions, thickness and compression are verified against the approved drawing.

A spiral wound gasket seals by even compression of a metal winding and a filler layer between two flange faces. SS Inner Ring Gasket Series is specified against the flange drawing rather than a catalogue size, because bore, winding density and ring arrangement all depend on the mating flanges. Qishine confirms the winding, filler and ring configuration per inquiry before the gasket is cut.

Name: SS Inner Ring Gasket Series
Note: Full dimensions and bolt pattern are confirmed per inquiry.

Start from the flange standard, facing type and bolt circle shown on the drawing. Confirm the bore clears the pipe ID and that the winding and filler suit the process medium; where an inner or centering ring is required, its material and thickness are checked together with the gasket. Final dimensions are confirmed per inquiry.

Clean both flange faces, check flatness and remove old gasket debris, then centre the gasket on the bore. Bring bolts up in a star pattern in several passes so the winding compresses evenly; do not reuse a gasket that has already been compressed. Recheck torque after the first thermal cycle and confirm the joint holds at operating pressure.

FAQ

Q1. What determines the winding and filler for this gasket?

The flange standard, facing, process medium and bolt load fix the winding metal and filler. They are confirmed per inquiry against the flange drawing; no material grade is assumed here.

Q2. Why is an inner or centering ring sometimes specified?

An inner ring protects the winding from radial buckling and erosion, while a centering ring locates the gasket within the bolt circle. Which rings are required is confirmed per inquiry from the flange drawing.

Q3. Can a spiral wound gasket be reused after opening the joint?

No. The winding takes a permanent set under bolt load, so a compressed gasket cannot recover its original seal. Fit a new gasket each time the joint is opened.

Q4. What payment terms do you accept?

T/T, L/C at sight and other internationally accepted terms. The exact terms are agreed with you before production starts, because the payment schedule has to match the order value, the shipping method and the delivery schedule you need — which is also why we confirm them up front rather than after shipment.
