Custom CGI Spiral Wound Gasket Manufacturer in China for sale

SS 304 with PTFE filler spiral wound gasket from Kaxite Sealing is a CGI-style semi-metallic gasket made with SS 304 / UNS S30400 V-shape winding and PTFE soft filler, complete with inner and outer rings. The PTFE filler provides excellent chemical resistance against most acids, alkalis, organic acids, inorganic acids and solvents, while the SS 304 winding delivers strength, spring-back and reliable sealing. Suitable for flat face and raised face flanges, high-pressure service and corrosive or toxic media. Available in ASME B16.20 dimensions, custom sizes, OEM private-label packaging and bulk quotations for B2B buyers. Send NPS, pressure class, filler, ring material, quantity and destination port for a firm quote.

Kaxite Sealing is a China-based SS 316L graphite filler spiral wound gasket manufacturer, producing gaskets from V-shape SS 316L stainless steel tape combined with a soft graphite filler, plus inner and outer rings. SS 316L is the regular molybdenum-bearing grade, second in importance to SS 304 among the austenitic stainless steels. The molybdenum content (2–3%) gives it better overall corrosion resistance than Grade 304 — particularly higher pitting resistance and chloride crevice corrosion resistance. The low carbon content (≤0.03%) eliminates carbon precipitation during welding, so SS 316L is resistant to sensitisation and is widely used in high-gauge (over 6 mm) welded parts. Chemical composition: Cr 16–18%, Ni 10–14%, Mo 2–3%, C ≤0.03%, Mn ≤2%, Si ≤1%, P ≤0.045%, S ≤0.03%. Mechanical properties: tensile strength 485 MPa, yield strength 205 MPa, elongation 52%, density 7.9 g/cm³. This is a very common and economical spiral wound gasket. As the direct supplier and manufacturer, we can offer factory pricing on short lead times. 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.

Kaxite Sealing is a China-based Monel 400 CGI spiral wound gasket manufacturer, producing gaskets from V-shape Alloy 400 (UNS N04400) tape combined with graphite, PTFE or vermiculite filler. Alloy 400 is a nickel-base alloy with resistance to a variety of corrosive conditions — most frequently specified in environments ranging from mildly oxidizing through neutral and in moderately reducing conditions. Its major application area is in marine environments and other non-oxidizing chloride solutions: it shows excellent performance against rapidly flowing brackish or seawater, outstanding resistance to chloride stress corrosion cracking, and good resistance to most alkalies, salts and organic substances. Mechanical properties: ultimate tensile strength 520 MPa, yield strength 240 MPa, elongation 48%, density 8.8 g/cm³, hardness 70 HRB. Chemical composition: Ni ≥63%, Cu 28–34%, Fe 2.5%, Mn ≤2%, C ≤0.3%, Si ≤0.5%, S ≤0.024%. Service from sub-zero temperatures up to 1020 °F (approximately 550 °C), with some capability in hydrochloric and sulfuric acids at moderate temperatures. Custom sizes, OEM private-label packaging and flexible MOQ are available for B2B buyers. Send your flange standard, nominal pipe size, pressure rating and filler material for a bulk quotation.
