Steel-reinforced Spirally Wound Pipe for Drainage

As plastic-steel winding drainage pipes are gradually widely used in municipal engineering, more and more customers are consulting the parameters of steel-reinforced spirally wound pipe, so we also put the parameter table of steel-reinforced spirally wound pipe below, the table The parameters in are all conventional parameters. If there is a customer who needs to customize steel-reinforced spirally wound pipe, please leave us a message.

Some customers who inquire about steel-reinforced spirally wound pipe want to consult more information about steel-reinforced spirally wound pipe because it is the first time to purchase steel-reinforced spirally wound pipe. The following content will introduce the connection, product features and application fields of steel-reinforced spirally wound pipe.

Clamp Elastic Connection

This kind of connection is suited for pipes with specifications of dn/ID200-dn/ID2800. At least two welded plastic sealing blocks are required at the sealing area in the spiral groove at the connection of the pipe ends. The height of the sealing blocks shall be identical to those of the reinforcing ribs. 

Electric Heat Melting Strip Connection

This kind of connection is suited for pipes with specifications of dn/ID800-dn/ ID2800. It is a connection method of welding the pipe ends of two steel-reinforced spirally wound pipes and the electric heat melting strip as a whole while using up the high temperature generated by the heating elements after they are electrified which are inlaid on the surface of the electric heat melting strip. 

Pros of steel-reinforced spirally wound pipe

Distinguished comprehensive performances: Worked as the braced structure, the steel belt offers enough ring stiffness to resist soil loading. PE pipe has excellent hydraulic characteristics, high ability for internal and external corrosion prevention, and moderate axial toughness. And SRWPE is an integrated advantage of steel and plastic. Therefore, this pipe possesses distinguished comprehensive performances. 

Safe and reliable ring stiffness: Steel and plastic have excellent modular ratios and are lightweight and their ratios are over 200 and 7.85. Strengthening the steel belt could be easily provided the pipes (especially the large diameter pipes) with enough safe and reliable ring stiffness and a fairly high weight ratio when compared with pure plastic pipes. 

Lightweight: Steel-reinforced spirally wound pipe has a fairly high stiffness-weight ratio; therefore, its weight is lighter than any other pure plastic pipes with the same ring stiffness. 

Simple installation, good sealing, and low cost of construction: Large-scale handling appliance is not required when installing lightweight pipes. Because of its good axial toughness, requirements of the undercut flatness are low when laying and firm. Moreover, it has good capabilities to bear abnormal stress caused by improper assembly. All sealed placements can be manually operated with simple equipment, simply and speedily without leak while no machine is needed. 

Producing on the construction site, saving the transportation charges and construction costs heavily: Shaped Steel-plastic composite strips can be coiled delivered. The device for winding strips is quite simple and tight. So it's very convenient for the manufacturer to deliver the device to the construction site and then produce pipes nearby. Transportation cost is heavily reduced by transporting strips instead of pipes. Without the need for transportation by oversize vehicles, the length of the pipe can be determined at random and a large number of interface connections and work to break pipes are reduced. So construction cost is reduced greatly.

Strong load capacity to resist improper burst: Because of the pipes are with high ring stiffness and good axial toughness, when burst load and disasters like soil differential settlement, ground water level rising, overload of part of the ground and earthquake happen, the stress can be defused through the elastic deformation of al pipes to avoid the leak or damage of the pipe connections.

Steel-reinforced spirally wound pipes have other advantages as the same as PE plastic pipes

• Anticorrosion: PE pipe can be used to deliver corrosive liquids like acid and alkali for its anticorrosion. The pipe can also be installed in corrosive environments such as moisture. Specific anti-corrosion performance is shown in standard ESO/TR 10358 

• Anti-ultraviolet: Carbon black stability factor is one raw material of PE pipe that is anti-ultraviolet. For this reason, the pipe could be used outside for a long time and there is no need to worry about the change in the pipe's nature. 

• Lightweight: Installation cost will be saved for the characteristics of easy, transportation and installation which result from being lightweight. 

• Smooth internal surface: The smooth internal surface of the PE pipe will minimize the energy loss caused by friction and sedimentation is not easy to produce. Friction drag is almost unchanged for long-term usage. 

• Impact resistance: High impact resistance of PE pipe leads to fewer fractures and damages during delivery and installation. 

• Easy installation: Welding joint after heating the PE pipe is going to assure the intensity of the connections and avoid the leak. 

• Toughness: Moderate toughness of PE pipes can make the pipes easily be installed along the pipe ditch, easily avoid obstacles when installing, and is suited for the soil settlement of the marshland and soft spots. 

• Nonpoisonous: Black HDPE pipe has passed the inspection of health-related departments and is licensed to use. 

• Abrasion resistance: The lifetime of HDPE pipe is four times longer than that of see pipe after the experiment of mortar abrasion. 

• Long operating life: The service life of the HDPE could be more than 50 years.

Applications of steel-reinforced spirally wound pipe

Because steel-reinforced spirally wound pipe is the perfect combination with all the merits of ordinary no-press plastic pipe and the high-strength of steel reinforcing segment, it can meet all demands in project applications completely. It can be widely used in gravity delivery with various media of corrosive or non-corrosive agents. Specific examples are as follows: 

• Public works: Used as blow-off pipe while buried under the ground. 

• Road works: Used as soaking away trench or drain pipes in railways and expressways. 

• Industry: Widely used as sewage pipe in industry areas. 

• Construction works: Used as rain pipes of buildings, underground drains, blow-off pipes, vent pipes and etc. 

• Dirty water collecting pipe in refuse landfills. 

• Large-scale port and wharf projects: Used as drain pipe and blow-off pipe in projects of large-scale airports, port,s and wharfs 

• Sports stadium: Used to soak away trench or drain pipes in a sports stadium, such as a golf course and football field. 

• Water conservancy project: Used as water-head pipe and irrigation pipe. 

• Minefield: Used as a vent, blast, drain, and slurry pipe. 

• Communication Engineering: Used as railway and highway communication, communication cable, and optical cable protective pipe. 

• Water storage system: Used in the water storage system to trap slow-flowing streams. 

• Agricultural engineering: Used as irrigation pipe on the farm, in the garden, tea garden, and the forest belt. 

• Seawater transporting pipe. 

• Clear the river channel
