Tobo Pipeline Equipments(Shanghai)Co., Ltd., is located in Shanghai,we are one of the biggest manufacturers Pipeline products in China .we are intelligent entity specializing in developing, manufacturing and selling pressure pipe units. The main products contain flanges, elbows, tees, reducers, bends, stub ends, caps, forged socket welding fittings and threaded fittings and the materials of its products contain carbon steel (A105, A106,A234WPB, A53,SS400), stainless steel (304, 304L, 316, 316L,321,316Ti ,304H,904L,UNS31803) and alloy steel(ASTM A234 WP1, WP12, WP11, WP22, WP5,A420WPL6 ). All products can be manufactured upon some standards such as American Standard ASME/ANSI and MSS, German Standard DIN, Chinese Standard GB/T, SH, HG, JB, SY and Japanese Standard JIS, while some non-standard products can be manufactured In addition, the insoluting joint developed and manufactured by our company can be widely applied to cathodic protection system of steeliness pipeline used in delivering oil, gas and water . ASTM A234 WP1, WP12, WP11, WP22, WP5,A420WPL6, A182 F304, F304L, F316, 316L,F321,316Ti ,304H,904L,UNS31803 UNS2205 ,UNS 32760,UNS2507,904L A105, A106,A234WPB, A53,SS400 The main products contain flanges, elbows, tees, reducers, bends, stub ends, caps, forged socket welding fittings and threaded fittings 　 　 　 Spiral Wound Gasket 　 　 SS316L/Graphite 　 　 Inner ring: SS316L; Outer ring: SS316L 　 　 36" x 600 Serie A piece 15 30" x 600 Serie A piece 70 24" x 600# piece 95 20" x 600# piece 6 30" x 150 Serie A piece 3 Spiral Wound Gasket 　 　 SS316L/Graphite 　 　 Inner ring: SS316; Outer ring: Carbon steel 　 　 The metal spirally-wound gasket adopts high-quality SUS304 or SUS316 ("V" or "W"shape) metal strips, other alloy materials and some flexible materials like graphite, asbestos, PTE and non-asbestos, which are overlapped and wound spirally with each other. The metal strips are fixed on the initial and terminal ends by means of spot welding. The metal spirally-wound gasket has the best resilien ce among the semi-metal hermetic gaskets. Its structural density can be made subject to different locking forces. Also the internal and external steel rings can be used to control its maximum compaction. It's not demanding for the surface precision of the flange sealing surface contacting the spirally-wound gasket. It's especially applicable for such occasions as uneven load, slack joint, periodical changes of temperature and pressure, impact or vibration. It's an ideal static seal element for flange connection in valves, pumps, heat exchangers, towers, manholes,handholes and so on.
