The steel pipes used in the manufacturing of pre-insulated pipes are manufactured longitudinally welded (ERW) or spirally welded (SAW) in accordance with the norms required by the standard TS EN 253 or customer demands.
Pipes comprise three basic materials.
Carrier pipes are established as steel, copper or plastic based according to the properties of the carried fluids.
Casing pipes are manufactured from high density polyethylene (HDPE) raw material, with UV resistance, 100% waterproof and with online corona. PUR ( POLYURETHANE INSULATION MATERIAL) that is injected between the carrier pipe and casing
pipe provides heat insulation besides enabling two
pipes operating as one pipe by bonding them together.
Galvanised steel pipes, which are resistant to and all kinds of wear such as corrosion etc. compared to black pipes, are manufactured as pre-insulated to prevent heat loss when used in service water installations, fire hydrant lines and boiler lines.
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, 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.
Pipe Fittings Metals offered for making butt-weld pipe fittings:
Monel, Nickle, Inconel, Hastalloy, Copper, Brass, Bronze, Titanium, Tantalam, Bismuth, Aluminium, High Speed Steel, Zinc, Lead Etc
