Introduction
Steel wire mesh reinforced plastic composite pipe is a newly improved type of steel reinforced plastic composite pipe. This pipe material is also known as SRTP pipe. This new pipeline is made from high-strength plasticized steel wire mesh and thermoplastic polyethylene as raw materials. The steel wire wrapped mesh serves as the reinforcing framework for the polyethylene plastic pipe, with high-density polyethylene (HDPE) as the matrix. The HDPE modified bonding resin tightly connects the steel wire framework with the inner and outer layers of high-density polyethylene, achieving excellent composite properties. Due to the high-strength steel reinforcement encapsulated within continuous thermoplastic, this composite pipe overcomes the respective disadvantages of steel and plastic pipes while maintaining their respective advantages.
Steel wire mesh reinforced plastic composite pipe, with high-quality materials and advanced production technology, boasts excellent pressure resistance. Additionally, the composite pipe features excellent flexibility, making it suitable for long-distance buried water and gas pipeline systems. The steel wire mesh reinforced polyethylene composite pipe uses polyethylene electric fusion fittings. During connection, the internal heating element of the fitting melts the outer plastic layer of the pipe material with the inner plastic layer of the fitting, fusing the pipe material and fitting together.
Materials used
Underground water pipes - PVC piping
ABS (-butadiene-styrene)
UPVC (rigid polyvinyl chloride)
CPVC (Chlorinated Polyvinyl Chloride)
PP (Polypropylene)
PE (polyethylene), also known as LDPE, MDPE, and HDPE (low, medium, and high density)
PVDF (Polyvinylidene Fluoride)
Material characteristics
ABS (-butadiene-styrene)
ABS is used for conveying drinking water, sludge, and chemicals. Commonly used in DWV (drain, waste, and vent) applications.
Excellent chemical resistance across the entire working temperature range with both rigid polyvinyl chloride (UPVC) and post-chlorinated polyvinyl chloride (CPVC), offering a wide working pressure range. Due to their long-term high-intensity properties, stiffness, and cost-effectiveness, UPVC systems account for a significant proportion of plastic pipeline installations.
CPVC is resistant to various acids, bases, salts, alkanes, halogens, and alcohols. It is not resistant to solvents, aromatic hydrocarbons, and certain chlorinated hydrocarbons. PP (Polypropylene) Polypropylene is suitable for use in food, drinking water, and pure water environments, as well as in the pharmaceutical, chemical, and other industries. PE (Polyethylene) Polyethylene has been successfully used for many years in the transmission of drinking water, wastewater, hazardous waste, and compressed gases.
PVDF (Polyvinylidene Fluoride) offers excellent chemical resistance, making it widely used in piping systems for corrosive liquids in the chemical industry.
Features
Overcame the rapid stress cracking phenomenon in plastic pipes; due to the composite structure of steel and plastic materials, rapid stress that is difficult to overcome in plastic pipes does not occur.
2. Features the strength, rigidity, and impact resistance of ordinary pure plastic pipes, along with characteristics similar to steel pipes, such as a low linear expansion coefficient and resistance to creep.
3. Lightweight, easy to install; features electric heat-fused pipe joints for strong axial tensile resistance; mature connection technology; a full range of pipe fittings in various types and specifications; compatible with a variety of other pipeline, valve, and equipment connections.
4. Double-sided corrosion resistance, with the same corrosion resistance as plastic pipes, high in usage temperature and corrosion resistance, and low thermal conductivity.
5. Excellent structure; the reinforced frame of the pipe material is integrated with the inner and outer plastic layers, ensuring no separation between the plastic layers and the reinforcing material.
6. Smooth inner wall, non-scaling, with a 30% lower head loss in pipeline flow compared to steel pipes.
7. The overall design of the piping material is for a lifespan of 50 years.
8. Tubes of varying pressure ratings can be manufactured by adjusting the wire diameter and the thickness of the plastic layer.
