Product Features

I. Core Areas of Municipal Infrastructure Construction

1. Urban Water Supply System

As the main water supply pipeline in cities, it replaces traditional cast iron/cement pipes, solves the problem of secondary pollution, and meets the hygiene standards of GB/T 13663-2018.

Case: Highway drainage pipe network, old community water supply renovation (non-excavation technology reduces road damage).

2. Gas Transmission Network

Used for medium and low-pressure natural gas/coal gas transmission, the interface strength reaches more than 90% of the main body, and the leakage rate is lower than that of traditional steel pipes.

3. Drainage and Sewage Separation

Urban wastewater discharge, rainwater collection system in sponge city construction, resistant to pH 2-12 corrosive media

II. Agriculture and Water Conservancy Engineering

1. Efficient Water-Saving Irrigation

Main pipelines for farmland drip irrigation/sprinkler irrigation systems, weather resistance adapts to a temperature difference of -50℃ to 60℃, and flow loss is 30% lower than steel pipes.

Case: Permeability exceeds 40% in China's rural drinking water safety project.

2. River Management and Dredging

Transporting abrasive media such as mine sand and slurry, wear resistance is more than 4 times that of steel pipes.

III. Industrial and Environmental Protection Scenarios

1. Chemical Media Transportation

Transportation of acid and alkali solutions in the petroleum and chemical industry (such as pH 2-12 environment), resistant to 275 kinds of chemical media

2. Environmental Protection Engineering

Industrial wastewater discharge, leachate transportation, zero permeability characteristics prevent soil pollution

IV. Innovative Applications in Special Scenarios

1. Non-Excavation Construction

Pipe jacking projects crossing railways/highways, bending radius reaches 20 times the pipe diameter, reducing 80% ground damage.

2. Power Cable Protection

Cable conduit application accounts for more than 25%, insulation performance is superior to PVC pipes, and pressure rating reaches SN8

3. Ships and Special Environments

Ship ballast water pipes, pipe networks in coastal salt spray areas, seawater corrosion resistance life exceeds 30 years

Connection Method: Hot Melt Butt Fusion Installation

1. According to the specifications of the pipe or fitting, select the fixture, extend the connecting end out of the fixture, the free length should not be less than 10% of the nominal diameter, move the fixture to make the connecting end face contact, and correct the corresponding connecting piece to make it on the same axis, the offset should not be greater than 10% of the wall thickness.

2. The connecting parts of the pipe or fitting should be wiped clean, and the connecting end face should be milled to make it perpendicular to the axis: the average thickness of continuous chips should not be greater than 0.2 mm, and the molten surface after cutting should not be contaminated.

3. The end face of the connecting piece should be heated using hot melt butt fusion equipment, and the heating time should meet the relevant standard regulations.

4. After the heating time reaches the process requirements, the heating plate should be quickly removed, and the uniformity of the melting of the connecting surface should be checked. There should be no damage: and the connecting surface should be quickly brought into full contact with uniform external force until a uniform and symmetrical burr is formed.

5. During the pressure-holding cooling period, the connecting piece should not be moved or any external force should be applied to the connecting piece.
