Spool Metallic Strip for SWG

Kaxite spool metallic strip for SWG is supplied as one joint-free length on 15–25 kg spools for spiral wound gasket winding machines, cutting coil changeover frequency compared with split-coil feeds. Standard materials include SS304/316/321/317L/31803, with exotic alloys on request. Thickness 0.16–0.50 mm, width 2.9–100 mm, flat or V-profile. Free samples for qualified winding lines from an ISO 9001 Ningbo factory.

Product Description

Spool Metallic Strip for SWG Winding Machines – Joint-Free 15–25 kg Spools for Spiral Wound Gasket Production

Kaxite spool metallic strip for SWG is supplied as a single continuous length of flat or V-profile stainless steel tape wound onto a 15–25 kg spool. Each spool feeds directly into a spiral wound gasket winding machine, eliminating the mid-run splices and manual reloads that interrupt winding when operators feed from split coils. The strip is wound together with graphite, PTFE or mica tape to produce spiral wound gaskets for ASME B16.20 and EN 1514-2 flange assemblies.

Split-coil feed — winding stops mid-run

Strip must be spliced or re-threaded during winding
Operators cut and discard partially wound bodies
Changeover frequency rises on long gasket runs
Each splice is a potential weak point in the finished winding

Kaxite spool strip — one uninterrupted length per spool

15–25 kg per spool, no joint within the spool
Continuous feed for the full run until the spool is empty
Fewer changeovers, less scrap on long gasket orders
Stable strip tension through the winder from start to end of spool

Where spool metallic strip fits in the SWG production line

Manual and semi-automatic winders. Standard 15–25 kg spools mount directly on most manual and semi-automatic SWG machines; operators thread the leading end once and wind continuously until the spool is empty.
Automatic winding lines. Custom spool weights and flange diameters are quoted to match automatic line feeders, avoiding mid-shift spool changes.
Pairing with filler tape. The metal spool runs in parallel with a filler spool such as graphite tape for SWG or PTFE tape for SWG, both available from the same Kaxite facility so the winding line sources both inputs from one purchase order.
Flat tape spooling. The same spool format is used for flat metallic tape that feeds double jacketed gaskets and eyelet forming; compare with the separate V-shape metallic tape page if you need V-profile in bulk coil form rather than on spool.

Bulk supply, custom spool weight and line-trial support

Kaxite Sealing produces spool metallic strip in Ningbo, Zhejiang, from a facility with more than three decades of sealing-material experience. Standard spool weight is 15–25 kg; custom spool weights and flange diameters are quoted on request to match customer winding machines. Standard MOQ starts at 50 kg per specification and is negotiable for trial orders. Free short-length samples are available for qualified winding lines; send the gasket standard, filler type, metal grade and monthly strip consumption, and Kaxite returns a spool specification and sample dispatch plan. Factory visits and video audits are welcome by appointment; ISO 9001 certificate details and third-party mill certificates for the strip are available on request.

Frequently asked questions

What is spool metallic strip for SWG used for?

Spool metallic strip is the continuous metal feed for spiral wound gasket winding machines. The strip is wound together with graphite, PTFE or mica tape on the machine to produce spiral wound gaskets. Kaxite supplies the strip on 15–25 kg spools with no joints within a spool.

Why does joint-free spooling matter for SWG winding?

A spool that contains one uninterrupted length of strip avoids the mid-run splice that forces operators to stop the winding machine, cut the gasket and re-thread. Joint-free 15–25 kg spools allow longer continuous winding runs, reducing changeover frequency and material waste on long gasket orders.

Which materials are available?

Standard materials include SS304(L), SS316(L), SS321, SS317L and SS31803. Exotic options include Monel 400, Inconel 600, titanium and Hastelloy C/B. The material must match the media and temperature of the flange service.

What spool weight and strip size can Kaxite supply?

Kaxite supplies 15–25 kg spools as standard, with custom spool weights on request. Strip thickness ranges from 0.16 mm to 0.50 mm and strip width from 2.9 mm to 100 mm. Flat and V-profile strip are both available on spool.

Do you provide free samples and factory audits?

Kaxite provides free short-length samples for qualified winding-line trials, freight collect. Factory visits and video audits are welcome by appointment. ISO 9001 certificate details are available on request.
