HDPE steel strip reinforced spiral corrugated pipe

Steel strip reinforced high-density polyethylene (HDPE) spiral corrugated pipe is a structural wall pipe made of HDPE and steel strip melt-compounding. The pipe wall structure consists of three layers: the inner layer is a continuous solid wall inner pipe; a corrugated steel strip reinforcement formed by winding a U-shaped annular corrugated steel strip around the inner pipe; and an outer layer of HDPE with the same corrugation as the steel strip reinforcement is compounded outside the corrugated steel strip reinforcement. The novel structure is scientific and reasonable.

High-performance PVC-UH water supply pipe

PVC-UH pipes for water supply use a unique green, environmentally friendly, lead-free formula system instead of the traditional composite lead salt formula system, so it will not damage the water quality and is sanitary and non-toxic.

HDPE reinforced spiral pipe

HDPE spiral-wound reinforced structural wall type B pipe, also known as HDPE spiral-wound structural wall pipe, KRALA pipe, HDPE spiral-wound type B pipe, high-density polyethylene spiral-wound pipe, and type B structural wall pipe. It is a new type of flexible pipe material with characteristics such as light weight, high strength, smooth inner wall, corrosion resistance, aging resistance, wear resistance, pressure resistance, strong impact resistance, good flexibility, and hygiene safety. It features high fusion quality, integral connection, good connection quality, 100% leak-proof, long service life, and quick and easy installation.

HDPE corrugated pipe

Made from high-density polyethylene (HDPE), this special pipe features a smooth inner wall, corrugated outer wall, and a hollow space between the inner and outer walls. It is mainly used in underground sewage and drainage systems. The socket uses a double-walled structure, expanded online during production. The double-walled structure is relatively rigid, and uses natural rubber for flexible connection. It is easy to install, the connection is reliable, leakage is unlikely, the overall cost is low, and the lifespan is up to 50 years.

PP corrugated double-wall pipe

This product is made from modified PP material: its inner wall is smooth, while the outer wall has a unique annular corrugated pattern, with a hollow space between the inner and outer walls.

HFB single-wall corrugated electrical conduit

Heat-resistant insulation, safe and reliable: The main material of the pipe is modified polypropylene, which has good insulation performance and can maintain good external pressure resistance even at high temperatures, making it suitable for use as a sheath pipe for high-voltage power lines. Tensile and pressure resistant, combining rigidity and flexibility: It has stronger tensile and external pressure resistance and good flexibility. The connection uses a clamp seal connection, which is convenient and reliable. Low temperature resistance, suitable for winter construction: As modified polypropylene, it has good low-temperature impact resistance. In most parts of southern China, construction can be carried out for most of the year. Reliable quality, cost savings: Light weight, density is only 0.9-0.92g/cm3, which is the lightest material among all buried pipe materials, greatly reducing transportation costs and installation hoisting costs; at the same time, under the same load conditions, HFB corrugated pipes only need a thinner pipe wall to meet the requirements, saving 40-70% of material costs compared with solid wall pipes with the same ring stiffness requirements; the comprehensive cost is basically the same as that of PVC double-wall corrugated pipes and fiberglass reinforced pipes, but the performance is superior. The construction connection adopts pipe coupling or hot melt welding, and there is basically no engineering maintenance cost.

IFB double-wall corrugated electrical conduit

IFB inner flat-wall corrugated electrical conduit, also known as CM composite reinforced double-wall corrugated electrical conduit, features a novel and unique structural design. It offers low frictional resistance, good flexibility, high-temperature resistance, high ring stiffness, and resistance to breakage and aging. Its hollow annular structure between the outer walls fully utilizes the principle of I-beam structure, increasing the section moment of inertia. The inner wall is very smooth, improving the efficiency of wire pulling. The product is widely used in excavation power projects and can replace HFB single-wall corrugated pipes, C-PVC electrical conduits, PVC-U communication conduits, and fiberglass pipes. The service life of this conduit is more than 50 years.

MPP non-excavation dedicated power cable sheath pipe

1. High tensile and bending strength 2. Good rigidity and toughness 3. High heat resistance 4. Strong corrosion resistance 5. Light weight and easy construction

CPVC electrical cable sheath

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.

Steel-strip reinforced polyethylene spiral corrugated pipe for drainage and sewage

Buried enhanced modified polyvinyl chloride (MPVC-SR) non-excavation dedicated communication pipe

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.

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.
