PVC_O pipe materials

PVC-O, known in Chinese as biaxially oriented polyvinyl chloride, represents the latest evolutionary form of PVC piping. This pipe material is manufactured through a specialized orientation processing technique that involves axially and radially stretching PVC-U pipes produced via extrusion. As a result, the long-chain PVC molecules within the pipe are arranged in an orderly, biaxially oriented manner, yielding a new type of PVC pipe with high strength, high toughness, excellent impact resistance, and superior fatigue resistance.

Product Introduction

Advantage

(1) Excellent impact and stress resistance performance
PVC-O achieves exceptional impact resistance through a biaxial stretching manufacturing process.
(2) Ultra-long service life
Its outstanding resistance to fatigue and long-term static hydraulic performance enable PVC-O pipes to have a service life of up to a century.
(3) High-efficiency water conveyance capability
The wall thickness of PVC-O subjected to circumferential tension is thinner, resulting in a larger water passage area.
The smooth inner wall of the pipe is environmentally friendly and naturally resistant to scaling, significantly reducing energy loss due to water flow during transportation.
(4) Excellent product flexibility performance
The acceptable deformation can reach up to 100% of the pipe’s inner diameter, and the pipe can immediately return to its original shape once the pressure is released, significantly reducing the risk of rupture caused by special conditions during construction, such as soil settlement, sharp stone abrasion, and mechanical compression.
(5) Corrosion-resistant and microbe-resistant
Compared to traditional metal pipes, which are highly susceptible to corrosion, PVC-O’s smooth inner wall combined with its outstanding chemical resistance makes it an ideal choice for modern clean and hygienic supply systems.
An excellent solution for water systems.
(6) Excellent environmental friendliness and hygiene
PVC-O is manufactured using high-quality raw materials, effectively eliminating secondary pollution during water transmission.
(7) Convenient transportation and installation
Compared to traditional PVC products, these are significantly lighter—weighing only one-sixth to one-twelfth of the weight of cast iron pipes with the same diameter. This lightweight design greatly reduces transportation and installation costs.
(8) Perfect sealing performance
Connected via a dedicated elastic sealing ring, this ensures greater safety, stability, and durability. Once the connection is complete, it will remain securely in place without shifting or loosening during use.

Polyethylene (hot) and cold water pipes (PP-R)

Product Introduction PPR pipes and fittings are pipeline systems manufactured according to GB/T18742, with random copolymer polypropylene as the primary raw material. Polypropylene can be categorized into three types: PP-H (homopolymer polypropylene), PP-B (block copolymer polypropylene), and PP-R (random copolymer polypropylene). Among these, PP-R has become the preferred material for producing polypropylene pipes designed for cold and hot water applications, offering long-term resistance to static water pressure, long-term resistance to thermal and oxidative aging, and excellent processability—making it ideal for achieving a service life of 50 years.

Features of corrugated pipes: Strong resistance to external pressure: The outer wall features a ring-shaped corrugated structure, which significantly enhances the pipe’s ring stiffness, thereby improving its ability to withstand soil loads. Performance characteristics: Compared with other types of pipes, HDPE double-wall corrugated pipes offer distinct advantages. Due to their lightweight nature, these pipes are easy to handle and connect, making construction quick and maintenance straightforward. These advantages become even more pronounced under tight schedules and challenging construction conditions. When made from HDPE, double-wall corrugated pipes can convey larger flows than other pipes of the same diameter—meaning that, for the same flow rate requirement, a smaller-diameter HDPE double-wall corrugated pipe can be used instead. They have a low friction coefficient, allowing for greater flow rates; they also exhibit excellent resistance to low temperatures and impact. The embrittlement temperature of HDPE double-wall corrugated pipes is -70°C. Under typical low-temperature conditions (above -30°C), no special protective measures are required during installation, making winter construction particularly convenient. Moreover, HDPE double-wall corrugated pipes demonstrate outstanding impact resistance.

Heat-resistant polyethylene (PE-RT)

Product Introduction Polyethylene pipe for hot and cold water systems, abbreviated as PE-RT in English. PE-RT is a non-crosslinked polyethylene material suitable for hot water piping. It is a new type of polyethylene product manufactured using a special molecular design and synthesis process. This material is a copolymer of ethylene and octene. In terms of molecular structure, its main chain consists of linear polyethylene, while shorter molecular chains of octene form its side branches. During the polymerization reaction, the number and distribution of side branches on the polyethylene chains are moderately controlled, giving the material excellent heat resistance and outstanding long-term resistance to static hydraulic pressure. PE-RT also features easy bendability without deformation or rebound, making it an ideal pipe material for underfloor heating systems. Product Features Long service life; good thermal stability and long-term pressure resistance, meeting 50-year usage requirements when applied in hot water piping systems. Excellent low-temperature impact resistance; PE-RT pipes have superior low-temperature impact resistance, making them less likely to crack under impact during winter construction. Hygienic and non-toxic; Meiergu brand PE-RT pipe products belong to the "healthy and environmentally friendly" category of green building materials. All hygienic indicators meet national hygiene standards and can be directly used in pure water delivery systems. Good flexibility; the pipes can be straightened or bent easily, facilitating installation. No preheating of the pipes is required during installation in low-temperature environments, making construction convenient. Environmentally friendly; the material is recyclable, does not pollute the environment, and qualifies as an eco-friendly and energy-saving product. Stable processing performance; PEX has issues such as difficulty in controlling crosslinking uniformity, leading to complex processing that directly affects pipe performance. In contrast, PE-RT is easy to process, and its pipe performance is largely determined by the raw materials, ensuring relatively stable performance. Good heat dissipation performance; PE-RT has excellent heat dissipation properties, with a thermal conductivity coefficient of 0.4 W/m·K. In heating applications, this enhances heat transfer efficiency and saves significant energy. Application Fields PE-RT underfloor heating pipes are suitable for residential buildings, villas, hotels, office buildings, shopping malls, hospitals, theaters, schools, libraries, exhibition halls, conference centers, swimming pools, entertainment venues, and more. PE-RT underfloor heating pipes are also used in industrial fields such as greenhouses, flower houses, machine rooms, fish farms, nurseries, livestock farms, airports, as well as outdoor ground snow-melting projects including stations, parking lots, and outdoor sports areas. Building cold and hot water supply, potable water piping systems. Also applicable in the food industry for fluid transport pipelines in beverages, alcoholic drinks, milk, and other liquid products. PE-RT Pipe Installation Methods 1.1 Lay down insulation boards and secure them to the floor with steel nails. 1.2 Choose an indoor layout configuration. 1.3 Lay out and fix the pipes according to requirements. 1.4 After the pipes are laid and installed, gather them together at the manifold installation location. 1.5 Secure the manifold in its dedicated box. Conduct system hydrostatic tests before pouring the concrete filling layer and again after the concrete curing period. 2. Construction Precautions 2.1 When bending PE-RT pipes, no heating is required. The bending radius should not be less than 8 times the outer diameter of the pipe. Use fixing clips to secure the pipe, and place clips every 12 cm along the bend. 2.2 During pipeline laying, follow the design specifications. Pipes must be laid horizontally and vertically, aligned in a straight line, and fixed at the marked positions on the insulation layer. For straight sections, use clips every 60 cm to prevent pipe deformation. 2.3 After laying the PE-RT pipes, lay the steel mesh in sequence, then pour cement mortar, and finally pave the floor. The height from the original ground to the finished floor should be between 70–100 mm. The steel mesh used should have a diameter of 25 mm and a mesh size of 50 mm in length and width. 2.4 At the beginning and end of the heating pipes where they extend above the ground and reach 1 meter from the manifold, install protective sleeves or other insulation measures to prevent damage to the pipes from the edges of the floor during flooring installation. 2.5 When installing the manifold, fix it either on the wall or in a dedicated box. When installed horizontally, the manifold should be placed above the collector, with a center distance of 200 mm. The center of the collector should be no less than 300 mm above the ground. When installed vertically, the bottom of the manifold should be no less than 150 mm above the ground. After securely connecting the underfloor heating pipes to the manifold, each circuit should be gradually flushed until clean water flows out of the pipes. 2.6 Before concealing the pipes, conduct a hydrostatic test on the pipes. The test pressure should be 1.5 times the working pressure of the pipes, but no less than 0.6 MPa. Conduct another system hydrostatic test before and after the concrete filling layer cures. The test pressure should be the working pressure at the highest point of the system plus 0.2 MPa, with the test pressure at the highest point of the system being no less than 0.4 MPa.
