Flat Stainless Steel Spool Metallic Strip Tape for Spiral Wound Gasket
Model:GR105
GR105 is a continuous spool stainless steel metal strip engineered for the spiral wound gasket winding line. Each spool is one continuous piece weighing 15–25 kg, eliminating the frequent reel changes that traditional small pancake rolls force on the operator. Thickness 0.16–0.50 mm, width 2.9–100 mm, with pre-matched widths for the standard SWG sizes — 4.8–5.3 mm for 4.5 mm SWG and 3.6–4.0 mm for 3.2 mm SWG. Stock materials span 304(L), 316L, 321, 317L, 31803, Monel 400, Ti, Inconel, Hastelloy C/B, and Zircaloy 702 — the same strip also serves double jacketed gaskets and gasket eyelets.

Continuous Spool Metallic Strip Tape for Spiral Wound Gasket Production — 15–25 kg Per Spool
GR105 is a **continuous single-piece spool** of flat stainless steel or nickel alloy strip engineered for the spiral wound gasket winding line. Where a traditional small pancake roll forces the operator to stop and change reels every few minutes, **one 15–25 kg spool runs much longer** — one continuous piece, no splices, fewer reel changes, and less scrap at the strip end. Thickness **0.16–0.50 mm**, width **2.9–100 mm**, ten material grades from **304 / 316L** to **Inconel, Hastelloy and Zircaloy 702**. The same strip also serves **double jacketed gaskets** and **gasket eyelets**. For the finished product, see Spiral Wound Gaskets.
Continuous Spool vs Traditional Small Pancake — Why It Matters on the Line

15–25 kgPER SPOOL · CONTINUOUS
One spool runs far longer than a small roll — the operator spends less time changing reels
Because each spool is one continuous piece, the strip end is only reached once every 15–25 kg — instead of the constant stop-start of small pancake rolls. That saves material changing time, reduces strip-end scrap, and keeps the winding line running.
Ten Material Grades — Stainless, Duplex, Nickel Alloy, Titanium, Zirconium
Austenitic 304 / 304L General-service stainless. Stocked in the standard SWG widths for the most common spiral wound gasket requirements.
Austenitic 316 / 316L Molybdenum-bearing stainless for improved chloride and chemical resistance. Standard grade for refinery and petrochemical SWG.
Austenitic 321 Titanium-stabilized stainless for elevated-temperature service where intergranular corrosion is a concern.
Austenitic 317L Higher molybdenum content than 316L for more aggressive chemical environments.
Duplex 31803 (2205) Duplex stainless with high strength and chloride stress-corrosion resistance — for offshore and aggressive chloride service.
Nickel Alloy Monel 400 Nickel-copper alloy for hydrofluoric acid, seawater, and alkaline service where stainless is not sufficient.
Reactive Metal Titanium Commercially pure titanium for oxidizing chemical service and where weight matters.
Nickel Alloy Inconel Nickel-chromium alloy for high-temperature and corrosive service — oxidation and carburization resistant.
Nickel Alloy Hastelloy C/B Nickel-molybdenum-chromium alloys for the most aggressive chemical service — wet chlorine, hypochlorite, strong acids.
Reactive Metal Zircaloy 702 Zirconium alloy for nuclear-grade and ultra-corrosive chemical service where no other metal is adequate.

One Strip, Three Applications — SWG, Double Jacketed, Eyelets
A1
Spiral Wound Gaskets V-shape flat strip interleaved with mica, graphite, or PTFE filler to produce the standard SWG. See Spiral Wound Gaskets and V-Shape Metal Strip for the alternative profile.
A2
Double Jacketed Gaskets Wider flat strip (up to 100 mm) forms the jacket and inner insert. See Double Jacketed Gaskets for the finished product.
A3
Gasket Eyelets Narrow strip wraps the gasket tag and eyelet — the same spool runs both eyelet and main gasket jobs without reel changes.

Procurement FAQ
What is a spool metallic strip tape, and why does it matter for SWG production?
It is a continuous single-piece roll of stainless or nickel alloy strip wound onto a spool, weighing 15–25 kg per spool. Its main advantage is that the operator does not need to stop the winding line to change reels as frequently — one continuous spool runs much longer, which saves material changing time and reduces scrap at the strip end.
What widths match the 4.5 mm and 3.2 mm SWG sizes?
4.8–5.3 mm width matches 4.5 mm spiral wound gasket strip; 3.6–4.0 mm width matches 3.2 mm strip. Other widths 2.9–100 mm are available for double jacketed gaskets and gasket eyelets.
Which material grades are available?
304 / 304L, 316L, 321, 317L, 31803 duplex, Monel 400, Titanium, Inconel, Hastelloy C/B, and Zircaloy 702. 304, 304L, and 316L are stocked in standard SWG widths; other grades are quoted against your end-user specification. See the ten material grade cards above for the specific service of each.
What thickness is available?
0.16–0.50 mm. The appropriate thickness depends on the strip width and gasket type. Send your SWG gasket thickness specification and we will confirm the exact strip thickness.
Can the same strip be used for double jacketed gaskets and eyelets?
Yes. The same spool strip also serves double jacketed gasket jacket and insert production, and gasket eyelet / tag ring production. Wider widths up to 100 mm are available for double jacketed gasket applications. See Double Jacketed Gaskets for the finished product.
What is the MOQ and lead time?
Stock grades and standard SWG widths are available from one spool for trial quantities; production orders are quoted by spool volume. Typical lead time for stock items is 10–15 working days; other grades and non-standard widths are quoted with a project-specific lead time.
