Kongwang steel strip polyethylene composite pipe is made by high-speed punching on high-quality thin steel plates, and then argon arc welding to form a perforated thin-walled steel pipe as a reinforcing body. The plastic is extruded to the inside and outside of the perforated thin-walled steel pipe, and the plastic on the inner and outer walls is firmly bonded together through the pores to form a whole with the reinforced thin-walled steel pipe. The production process is as follows: steel strip unwinding → high-speed punching → perforated plate strip coiling → perforated plate strip unwinding → perforated plate strip butt welding → perforated plate strip storage → perforated plate strip precision edging → perforated plate strip compensation → perforated plate strip rough forming → perforated thin-walled steel pipe precision forming → perforated thin-walled steel pipe butt welding → eddy current flaw detection → perforated thin-walled steel pipe preheating → extrusion compounding → vacuum sizing → cooling → inkjet printing - traction → cutting → stacking → inspection → end cap → trimming → inspection → packaging and warehousing.
CPVC electrical conduit uses heat-resistant, excellent insulation PVC-C resin as the main material. CPVC products are currently recognized as green and environmentally friendly products, and their excellent physical and chemical properties are increasingly valued by the industry. CPVC electrical conduit is a rigid, solid-wall pipe with smooth inner and outer walls. It is orange-red in color, bright and eye-catching.
The anti-static and flame-retardant components of polyethylene pipes used underground in coal mines are uniformly distributed throughout the pipe body, so the anti-static and flame-retardant performance indicators will not be affected by long-term use. The anti-static and flame-retardant properties meet national standards and are suitable for flammable and explosive environments underground.
Plastic well casings are lightweight, corrosion-resistant, durable, and inexpensive. In foreign countries, especially developed countries, over 80% of water wells use plastic casings. The future trend in the water well field is to use new materials for well construction to solve corrosion and scaling problems, especially corrosion problems in high-salt areas. PVC-U plastic pipes have the advantages of low cost, no corrosion, and long service life, so they have broad application prospects and market. Does not pollute water quality High burst strength, good seismic performance Inexpensive pipe materials, low well construction cost
Buried Enhanced Modified PVC (MPVC-SR) Non-Excavation Dedicated Communication Pipe Currently, in communication non-excavation projects, PE pipes and silicon core pipes are mainly used. Our company's newly developed new generation of communication non-excavation dedicated pipe MPVC-SR is superior to PE pipes and silicon core pipes in terms of performance, connection methods, procurement costs, and transportation. The pipe is placed in a -15°C freezer and frozen for 1 hour before impact testing; it does not break. A convenient, ultra-high-strength connection method uses a special adhesive connection, which is easy to connect, and the strength of the connection is higher than that of the pipe body itself. MPVC-SR pipe has flame-retardant self-extinguishing properties, and its flame-retardant performance exceeds V0 grade, which is very beneficial for fire safety; the raw materials use hygienic and environmentally friendly polymer materials and additives, and the pipe material entering the soil does not pollute the environment or soil. The pipe is buried to four-fifths of the outer diameter of the pipe, with one-fifth exposed. A 20-ton road roller with level 3 vibration repeatedly rolls over it, and the pipe does not break. The raw material of MPVC-SR pipe is mainly calcium carbide, the price of calcium carbide is stable and the cost is low; its coefficient of friction is 0.25-0.35, the inner wall is smooth, the wire pulling resistance is small, and the out-of-roundness of the outer diameter is less than 1-3%, so the inner diameter utilization space is large, and the cost performance is far superior to HDPE pipes and silicon core pipes. MPVC-SR pipe meets the requirements of special scenarios, adapts to construction sites with walls and houses, and can be connected while pulling. And no power is needed for connection or repair; at room temperature, special glue can be used directly for socket connection, which is flexible and convenient.
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.
1. Corrosion-resistant and long service life. In coastal areas, the groundwater level is high and the land is humid. Metal or other pipes must be protected against corrosion, and their service life is generally only 30 years, while PE pipes are resistant to various chemical media and are not affected by soil corrosion. 2. Good toughness and flexibility. PE pipe is a high-toughness pipe material with a breaking elongation of more than 500%. It is highly adaptable to uneven ground settlement and displacement. It has good seismic resistance. Small-diameter pipes can be bent arbitrarily. 3. Smooth pipe wall, low friction coefficient, easy cabling, high construction efficiency, and low construction cost. 4. Good electrical insulation performance, long service life (underground pipe life over 50 years), durable, and reliable line operation. 5. Light weight, easy maintenance, installation, and operation, easy to transport and operate. 6. Small-diameter pipes can be used in coil form, with long pipe sections and few joints, making installation simple. 7. Pipes can be made in various colors for distinction. 8. Excellent low-temperature impact resistance. The low-temperature embrittlement temperature of PE is extremely low, and it can be safely used in the range of 20-60°C. During winter construction, the material's good impact resistance prevents pipe cracking. 9. Good wear resistance. Compared with other metal pipes, PE pipes have four times the wear resistance of metal pipes. 10. Convenient connection, various new construction methods can be used. In addition to traditional excavation methods, PE pipes can also be constructed using various new trenchless technologies, such as pipe jacking, pipe lining, and pipe bursting. This is the only option for places where excavation is not allowed.
