It is mainly suitable for quick repair of straight pipeline leakage, with pressure plugging, no need to stop pressure, no welding and no fire risk.

Galvanized pipe tee repairer is a device specifically designed for rapid repair of galvanized pipe tees. It is suitable for pressure repair of pipe sand holes, cracks, fractures, and other issues without the need to stop water or replace pipes.

Scope of application

Low soil disturbance, good at dealing with complex geological conditions, especially suitable for complex projects in old urban areas, crossing roads / building underground, overburden depth of less than 2 meters.

Suitable for silt, sand layer, especially suitable for strata with high water table.

Suitable for sand, gravel, pebble, boulder and rock formations. Especially suitable for hard rock geology. The strength can exceed 150 MPa.

They are suitable for all kinds of geology and apply the patented technology to deal with complicated geology. Especially suitable for soil, sand, dense soil, mixed weathered rock, and can also break up sandstone, rock, and multiple obstacles, etc.

The aerogel composite foamed polyurethane material is formed by adding a thermal insulating material silica aerogel pore filler and a phosphorus heat-resistant modifier to a conventional rigid polyurethane foam (RPUF).

Rust converter is a special functional coating that is applied to the surface of rusty steel, where unwanted rust is converted into a useful black anti-rust film. The anti-rust film is non-conductive, which can effectively prevent electrochemical reaction and perforation corrosion. Stable performance in a range of 40℃ 1500°C, with excellent fire resistance.

Prestressed steel strand is a twisted steel cable composed of 2, 3, 7, or 19 high-strength steel wires. It can be divided into 7-wire, 2-wire, 3-wire, and 19 wire structures according to the number of steel wires, and the commonly used 7-wire structure. 

The non bonded steel strand has a rubber sheath on the outside, mainly used for post tensioned prestressing systems, which always allows longitudinal relative sliding between the prestressing and the surrounding concrete.

High strength 1960MPa prestressed steel strand is a material widely used in construction engineering, bridges, roads and other fields, with extremely high strength and excellent performance. 

Border Guardrail made of high-strength galvanized steel and treated with dual anti-corrosion technology, it is resistant to wind and sand, corrosion, and suitable for extreme environments ranging from -30 ℃ to 70 ℃, with a service life of up to 20 years.

Community guardrails are protective facilities designed specifically for residential  areas,  usually  made  of  high-strength,  corrosion-resistant materials.
