Wenzhou Meike Valveco.,ltd

we offer Line Blind Valve. Industry Using Line Blinding Systems: Metallurgical valve primary use is to completely close off the downstream portion of a pipeline in a safe way. They are frequently found in the Petrochemical, Steel, Pulp and Paper, Maritime and Oil & Refinery industries. They are often referred to as spectacle blinds, figures of eight, spectacle plates or paddle blinds. Line Blind Valve Applications Positive pipeline closeoff is vital in many piping systems to assure safety of personnel working on downstream equipment, particularly when flammable, toxic liquids or gases could sleep past a closure. When visible proof of shutoff is necessary, a line blind is mandatory to comply with plant safety regulations. Available in three variants as Cam-Set, Cam-Slide or Line Blind Valves(Metallurgical valve). Key Characteristics of the Cam-Set: Absolute positive Shut-Off No spreading of pipe required Seal unaffected by piping misalignment Simple, one man, spectacle changing from one side of the line 316 SST as standard, other materials upon request Special anti corrosive coatings such as epoxy, polyurethane and Sermetel ceramic are available if required Spectacle Blind Valve Sizing: Line Blind Valve is available in sizes ranging from 1 to 48 inch (larger on request) and can be supplied in 150, 300 and 600 ASME ratings. Other sizes and pressure ratings are available on request. Materials used in Line Blind Valves Line Blinds are available in carbon steel, stainless steel (316 SST) as standard. Others materials are application and request dependant. A pipe line is blinded with a spectacle plate by swing the open close position. It allows one person to blind deblind a heavy pipe line within minutes by operating a hand wheel. Product range is from DN 20 (NPS 12) to DN 800 (NPS32) up to 1500 LBS (ASME class) for gases, liquids, viscous liquids, slurry, powder, chips and etc

We offer Duplex Strainers - Duplex strainers remove damage causing particulate matter from the process media, and never have to be shut down for cleaning…the line can run continuously. When one strainer basket becomes full, flow is switched to the other. The first basket is removed, cleaned and is ready for use again. The Model FD150 can be custom fabricated to meet the requirements of unique applications. If a standard duplex strainer won't work in your application FSI can help you design a custom Duplex Strainer to your specifications. They are available with either manual or automated operation. Materials of Construction: Carbon steel, stainless steel Flanged Connections: ANSI 150#, 300# Design: Butterfly or ball valve duplex arrangement Cover: Bolted or quick-opening hinged Basket: Perforated or mesh stainless steel Options: Alloy construction for body or baskets, automated operation, ASME code construction

We offer Hastelloy Valve. Hastelloy C-276 Chemical composition Hastelloy C-276 Alloy m inimum mechanical properties in the room temperature Alloy state Tensile strength Rm Nmm² Yield strength R P0. 2Nmm² Elongation A 5 % C C276 690 283 40 Characteristic as below 1.Excellent corrosion resistance to most of corrosion media in oxidation and reduction environments. 2.Excellent resist pitting, crevice corrosion and stress corrosion cracking performance. Hastelloy C-276 Metallurgical structure C276 is face-centered cubic lattice structure. Hastelloy C-276 Corrosion resistance C276 alloy suit for many kinds of chemical process industry which contain the oxidizing medium and reductant. High molybdenum and chromium content make it can resist the chloride corrosion, and tungsten make it corrosion resistance better.C276 is one of a few material that can resist the corrosion of most chlorine, hypochlorite and chlorine dioxide, this alloy have prominent corrosion resistance to high concentration chlorate( iron chloride and copper chloride). Hastelloy C-276 Application field: C276 is widely used in the chemical field and petrifaction field, such as the element of chloride organic and catalyze system.This material especially suit for high temperature environment, impure inorganic acid and organic acid (such as formic acid and acetic acid), sea-water corrosion environment. Hastelloy C-276 Other application field: 1. The digester and bleacher in the use of paper pulp and paper making industry. 2.Absorption tower, re-heater and fan in the FGD system. 3. The equipment and parts in the use of acidic gas environments. 4. Acetic acid and anhydride reaction generator 5. Sulfur acid cooling 6.MDI 7.Manufacture and processing of impure phosphoric acid.
