HDPE gas pipe

PE pipes have an elongation at break of over 500%, and will not rupture under various ground subsidence and seismic crustal movements, demonstrating high safety. With a bending radius (R≥15D), pipe bending fittings are unnecessary, simplifying construction. The coefficient of linear thermal expansion of PE pipes is 1.5X10-4mm/mm℃, meaning their length is almost unaffected by temperature changes, and they do not undergo physical changes even at -80℃, making them especially suitable for use in severely cold regions.

    Durable and Safe - Primarily used in urban gas projects

    Long Lifespan

    Safe for use for over 50 years

    Flexibility

    PE pipes have a fracture elongation rate of over 500%, and will not rupture under various ground subsidence and seismic crustal movements, demonstrating high safety. Bending radius (R≥15D), eliminating the need for bending pipe joints, facilitating construction.

    Cold Resistance

    The linear expansion coefficient of PE pipe is 1.5X10-4mm/mm℃, its length is almost unaffected by temperature changes, and it does not undergo physical changes even at -80℃, making it particularly suitable for use in severely cold regions.

    Weldability

    PE pipes can be connected using electrofusion or heat fusion methods, ensuring the connection is complete, tight, and absolutely leak-proof.

    Corrosion Resistance

    Acid Resistance

    At room temperature, PE pipes are unaffected when immersed in solutions such as hydrochloric acid, sulfuric acid (≤70%), nitric acid (≤25%), phosphoric acid, hydrofluoric acid, and complex acids (≤10%).

    Alkali and Inorganic Salts

    At 60℃, PE pipes do not corrode when immersed in various alkaline solutions, inorganic salts, and seawater.

    Organic Substances

    At room temperature, PE pipes are resistant to organic solvents such as hydrogen peroxide and gasoline, without undergoing corrosion.

    Workability

    PE pipes are lightweight (only 1/7 the weight of steel pipes) and highly flexible. De16-De75 pipes can be coiled, facilitating transportation and construction.

PE wear-resistant pipe

PE wear-resistant pipe

PE wear-resistant pipe is a high-density polyethylene pipe made from modified ultra-high molecular weight polyethylene as raw material, with the addition of antioxidants, UV absorbers, flame retardants and other additives, through extrusion molding and injection molding processes. Its main features include excellent wear resistance, high internal pressure strength, good impact resistance, excellent low temperature performance and strong corrosion resistance.

PPH chemical pipe

PPH chemical pipe

PPH chemical pipes (Polypropylene-Homo, abbreviated as PPH) are alloy polypropylene pipes formed by β-modification of ordinary polypropylene materials, with a uniform and fine Beta crystalline structure. PPH chemical pipes are widely used in the chemical industry, mainly due to their excellent chemical corrosion resistance, high-temperature performance, and good physical properties. Characteristics Chemical Corrosion Resistance: PPH chemical pipes have the strongest chemical corrosion resistance among all polypropylene pipes and can withstand long-term corrosion by various acids, alkalis, and salts. High-Temperature Performance: The operating temperature can reach 100℃, and the applicable temperature range is -20℃ to 110℃, combining low-temperature impact resistance with high-temperature pressure resistance. Physical Properties: PPH chemical pipes have low density and light weight, making them easy to transport and install; they also have high strength and can withstand a certain amount of pressure. Insulation: They have good electrical insulation properties, are non-conductive, and are suitable for pipeline systems in the power industry. Application Areas Chemical Industry: PPH chemical pipes are often used to transport various chemical media, such as acids, alkalis, and salt water, and are widely used in the chemical industry due to their excellent corrosion resistance. Pharmaceutical Industry: Used to transport medicines and chemical reagents, ensuring that they do not react with the medicines and maintain the purity of the medicines. Food Industry: Meets food safety standards and is often used in food processing and transportation to ensure food safety and hygiene. Construction Industry: Used in the water supply and drainage systems of buildings, and due to their corrosion resistance and high-temperature resistance, they can effectively extend the service life of the pipelines. Power Industry: Due to their good insulation properties, they are often used as cable protection pipes in the power industry.

UPVC industrial pipe

UPVC industrial pipe

Corrosion Resistance: UPVC pipes are renowned for their excellent corrosion resistance, capable of withstanding the erosion of most acids, alkalis, salts, and other chemical substances. This makes them very popular in the chemical, industrial, and wastewater treatment fields. Temperature Resistance: UPVC pipes have relatively low temperature resistance and usually cannot exceed 60℃, otherwise they will deform or soften, limiting their application in high-temperature environments. Flexibility: UPVC pipes are rigid pipes that are not easy to bend. Precise measurement and cutting are required before installation, demanding high construction skills. Installation Convenience: UPVC pipes are usually connected using adhesive bonding or mechanical connections. The connections are well-sealed, but the installation process is relatively complex and requires professional skills and tools. Service Life: UPVC pipes have a long service life, typically exceeding 50 years. The actual lifespan depends on the operating environment, medium properties, and maintenance.
