Custom CG Spiral Wound Gasket Manufacturer in China

Style CG spiral wound gasket from Kaxite Sealing is a general-purpose semi-metallic gasket with a V-shape metallic winding and a solid outer guide ring. The outer ring centers the gasket on the flange bolt circle, resists blowout and provides a compression stop. Suitable for flat face and raised face flanges up to and including ASME Class 2500. Standard gasket thickness 4.5 mm (0.175") with 3.2 mm (0.125") solid outer ring, unless otherwise specified. Winding alloys: SS 304, 304L, 316, 316L, 316Ti, 310, 321, 347, 410, Inconel 600/625, Monel 400, Titanium, Nickel, Incoloy 800/825, Alloy 20, Hastelloy B2/C276. Fillers: flexible graphite, PTFE, non-asbestos or vermiculite. Manufactured to ASME B16.5, BS 1560, BS 10, ASME B16.47 Series A/B, BS 4504 and DIN flange standards. MOQ 10 pcs, lead time 7–30 days, custom sizes and OEM marking available. Send your flange specification for a firm quotation.

Kaxite Sealing is a China-based SS 304 CG spiral wound gasket manufacturer, producing gaskets from SS 304 stainless steel winding with an outer guide ring only — the CG configuration per ASME B16.20. SS 304 is the most common form of stainless steel used around the world due to its excellent corrosion resistance and value. It can withstand corrosion from most oxidizing acids, and its durability makes it easy to sanitize — ideal for kitchen, food and general industrial applications. The basic steel alloy composition is 18% chromium and 8% nickel, with carbon, manganese, silicon, phosphorus and sulfur making up the balance. This gives SS 304 a well-balanced combination of weldability, corrosion resistance and oxidation resistance. Chemical composition: UNS S30400, Cr 18–20%, Ni 8–10.5%, C ≤0.08%, Mn ≤2%, Si ≤0.75%, P ≤0.045%, S ≤0.03%. Mechanical properties: tensile 550 MPa, yield 230 MPa, elongation 51%, density 7.93 g/cm³, hardness 85 HRB. The CG style carries an outer guide ring but no inner ring, and is suitable for male and female pipe flanges. Very suitable for flat bottom groove flanges, natural gas and power generation, hydrocarbon processing and refining, petrochemical processing, chemical processing, and oil and gas industries. Custom sizes, OEM private-label packaging and flexible MOQ are available for B2B buyers. Send your flange standard, nominal pipe size, pressure rating and quantity for a bulk quotation.
