  COMPANY  INFORMATION   1,pecializes in developing sealing materials and gaskets about 15 years. 2, located in the south of Hangzhou Bay, near Hangzhou and Ningbo. 3,convenient transportation and good geographic advantages.
4, high quality products and service and reasonable prices. 5,customers all  over the world. PRODUCT  DESCRIPTION   There are four types of sprial wound gasket: the basic type, the inner ring, the outer ring, and the inner&outer ring. Its widely used in electric power plant, chemical industry, chemical fertilizer plant, Polycrystalline silicon plant, Petrochemical plant, valve, flange, vessel and so on. The sprial wound gasket are good at high temperture, high pressure and erosion resistance.   The material of Sprial Wound Gasket has two parts, the metal part and the non-metal part. 
The metal part: Carton Steel, 304, 304L, 316, 316L, Ti, Monel, Ni, Hastelloy alloy, Inconel
The non-metal part: Graphite, PTFE, Non-Asbestos, Asbestos

  GASKET SELECTION   Style CG - Utilizes an external ring which accurately centers gasket on flange face, provides additional radial strength to prevent gasket blow-out and acts as a compression stop. A general purpose gasket suitable for use with flat face and raised face flanges up to and inclusive of class2500. Style CGI - A Style CG gasket fitted with internal ring which gives an additional compression limiting stop and provides heat and corrosion barrier protecting gasket windings and preventing flange erosion. Suitable for use with flat face and raised face flanges. Style R - Basic construction type. Inner and outer diameters are reinforced with several plies of metal without filler to give greater stability and better compression and sealing characteristics. Suitable for tongue and groove or male and female or grooved to flat face flange assemblies Style RIR - Solid inner metal ring acts as a compression stop and fills the annular space between flange bore and the inside diameter of the gasket. Designed to prevent accumulation of solids, reduce turbulent flow of process fluids and minimize erosion at flange faces. Suitable for male and female pipe flanges.     GASKET IDENTIFICATION    Package         Ordering  Information   When ordering gaskets please specify the following: Gasket style and number Material Nominal pipe size and pressure rating or specific gasket dimensions   why choose us?   1) Any inquiries will be replied within 24 hours  2) Professional manufacturer.Welcome to visit our website:  3)genuine products with excellent quality 4)provide after sales service as the customer's requirement and needs 5) provides just-in-time delivery with its streamlined supply chain 6)less cost of purchase:   Rilson is a direct importer and agent of many manufacturers around global, so there are no intermediary costs involved.     Note: the photo above shows a small selection of our company, which carried to suit our customers' individual requirements. we look forward to being of service.     If you are interested in our products, please feel free to contact with me directly, thank you!
