Pipe fittings are the general names of parts and components that play the role of connection, control, direction change, diversion, sealing and support in the pipeline system. Steel fittings are pressure fittings. According to the different processing technology, it is divided into four categories, namely, butt welding pipe fittings (divided into weld and no weld), socket welding and threaded pipe fittings, flange pipe fittings. According to the application: 1. pipe fittings for connecting pipes are: flanges, live joints, pipe hoops, clamps, clamps, throat hoops, etc. 2. changing the direction of the pipe: bends, bends. 3. pipe fittings changing pipe diameter: variable diameter (different diameter pipe), different diameter elbow, branch pipe table, reinforcing pipe. 4. pipe fittings with additional piping branches: three links, four links. 5. pipe fittings for pipe sealing: gasket, raw material belt, thread hemp, flange blind plate, pipe plug, blind plate, head, welding plug. 6. pipe fittings for pipe fixing: clasp, hook, ring, bracket, bracket, pipe clamp, etc. According to the connection :1, welded pipe fittings 2, threaded pipe fittings 3, clamping pipe fittings 4, clamping pipe fittings 5, socket pipe fittings 6, rubber ring connection pipe fittings According to the material divided into 1, cast steel pipe fittings 2, forged steel pipe fittings 3, alloy pipe fittings 4, stainless steel pipe fittings. Pipe fittings are widely used in municipal, petrochemical, west-to-east gas transmission, ships and nuclear power.

MSVA Ammonia Stop Valves are accessible with Standard neck (MSVA-S) in angle way and straightway variants. Ammonia stop valves are specially designed to meet all modern refrigeration application necessities and favorable flow characteristics. These Ammonia Stop valves are very easy to disassemble and repair when required. The Ammonia stop valve cone is intended to ensure perfect sealing and withstand a high pulsation and vibration, which can be present particularly in the discharge line. The MSVA is furnished with internal back seating support/enabling the shaft seal (packing gland) to be replaced while the Ammonia stop valve is still under working condition. Highlights Applicable to R717(Ammonia), R744(CO2), HCFC and HFC. Also utilized in chemical and petrochemical applications. Each valve type is clearly mentioned with type, size and operating range. Quick and simple valve maintenance. It requires less effort to replace the top assembly and no welding is required. Modular Concept Each valve body is available with a number of different sizes and connection types. Possible to transform/convert MSVA-S into any other product of MSVL family (stop/check valves, regulating valve and strainer) by replacing the entire top part. Optional accessories: For frequent operation heavy duty hand wheel can be supplied. For infrequent operation seal Cap can be supplied Available in angleway and straightway forms with Standard neck. The valves and seal caps are prepared for sealing, to avoid operation by unauthorised person, utilizing a seal wire. Internal back seating: Internal metal backseating: -DN 15 - 65 (�½ - 2�½ in.). Internal TEFLON backseating: DN 80 - 200 (3-8 in.). Can be used for flow in both directions. Valve body and bonnet material is low temperature steel as per PED norms. Maximum working pressure: - 754 psi g (52 bar g). Operating temperature range: - 60 to +150C ( 76 to 302F).
