Modified polypropylene (MPP) power cable protection tube is modified polypropylene as raw material, through extrusion forming processing. It can not only use traditional excavation method, but also trenchless pipe-jacking way. Compared with the traditional "excavated buried pipe method", trenchless method is more suitable for the current environmental protection requirements of no dusty and easy transportation. This technology can lay pipe in some areas cannot be implemented excavation work (such as urban, cultural relics protection, crops protected areas, highways, rivers etc.). MPP pipes diameter is 110-250mm, normal and reinforced two types. Normal one is suit for the excavation and trenchless across bury construction less than 4 meters. The reinforced type is suit for trenchless across bury construction more than 4 meters .

PE coil pipes and tubes for water and wire cable conduit PL231
The PE coil pipes and tubes can be used:
water pipe 4 â?? 6 â?? 1-inch black coil with pressure 1.6mpa, OD 20-75mm, WT 2.3-6.8mm
pe conduit cable embedded wire cable and optical cable, OD 20-200mm, WT 1.8-3.5mm
weak current protection tube and communication tube, OD 20-200mm, WT 1.8-3.5mm
We use new 100% pure raw PE material
WHY NEW MATERIAL HDPE PIPES?
1. Health performance
PE pipe processing without adding heavy metal salt stabilizer, no scaling layer, and no bacteria.
2. Corrosion resistance
It can resist various chemical media erosion, with no electrochemical corrosion.
3. Service life
Under rated temperature and pressure conditions, PE pipes can be used for more than 50 years.
4. Impact resistance
PE pipe toughness, high impact strength, heavy objects directly pressed through the pipeline will not break.
5. Connection performance
The strength of the hot melt or electric melt interface of the polyethylene HDPE pipe is higher than that of the pipe body, and the joint will not be broken due to soil movement or live load.
6. Construction performance
It has a lightweight pipe weight, a simple welding process, convenient construction, and a low overall project cost.
Cast Iron and Ductile Iron tube and fittings PL739
Cast Iron and Ductile Iron tube and fittings can be offered by our comapny to meet different engineering needs.
The difference between ductile iron and gray iron
1. Different chemical composition
Nodular cast iron contains nodular graphite, which can improve its toughness and strength, while reducing brittleness. Gray cast iron contains a lot of carbon, so that its hardness and wear resistance is high, but the toughness is poor.
2. Different organizational structures
The structure of nodular cast iron contains nodular and ferrite, and the distribution of nodular is uniform. While the structure of gray cast iron is mainly ferrite and pearlite, and the distribution of pearlite is uneven.
3. Different performance
Ductile iron has high strength and toughness, and has good corrosion resistance. It is uitable for the manufacture of high load and high pressure parts. The hardness and wear resistance of gray cast iron are high. It is suitable for the manufacture of friction and wear parts.
Application field
Cast iron : because of its low strength and good vibration resistance. It is often used in the production of parts under compressive stress, such as box, base, etc.
Ductile iron : because of its high strength and good toughness. It is often used in the manufacture of parts requiring high strength and toughness, such as crankshaft, connecting rod and so on.
Circular steel pipe is both openings and have hollow concentric sections of steel larger than the surrounding. The specifications of steel pipes are indicated by appearance dimensions and inner diameter and wall thickness, with a wide range of dimensions from very small diameter capillary to large round steel pipe of several meters in diameter. Round steel pipes can be used for pipelines, thermal equipment, machinery industry, petroleum geological drilling, containers, chemical industry, and special uses. It can be divided into seamless, ERW, LSAW, SSAW steel pipe according to the production process.
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.
