Underfloor heating tubular system

"Haolong" brand tube is not easy to become deformed under pressure. it is characterized by good flexibility, fewer joints, avoiding the obstructed flow rate and leakage and has larger use scope of temperature(-40°C-95°C)。It is a new-type building material for environment protection and is good for the health. This building material has been widely used abroad, and it is been gradually popularizing at home.

Solar air-conditioning tubing system

Haolong tubes facilitatethe instllation, insusceptible to frost, high heat preservation and low heating cost, and can betterthe performance of using solar energy as well as air-conditioning system.

Cold & hot tubing system

Haolong tubes are smooth inside,stainless.
leaving no scale and 30%bigger than metallic pipes in volume.Haolong tubes can bend easily round the columns and beams,can be buried in the walla and concrete.so the Haolong tube serves well in the cold & hot water pipe systems.

Indoor gas tubing system

Haolongtubes can stand a high load and the penetration rate of oxygen is zero. Meanwhile,long tubes help lessen the tie-ins in case of leakage.
So the haolong tubes are well applied in gas transportation system carrying compressed air,fuel gas,oxygen,etc.　

Tubing systems for pharmaceutical, food and chemical industries

"Haolong" brand tube is not easy to react chemically with other substances. It does not leak and is safe and good delivered through the system is pure and safe. In food industry,the liquid delivered through the system will not be polluted and corrodred.PEX tubes can bear the corrosion of various concentrations of acids and alkalis.Therefore,it may be used in petrochemical industry.

Broad range of uses

Floor heating of residence, hospital, hotel, classroom, office building, library, market, exhibition center, swimming pool, theatre, in-door stop stop or station; ground snow melting of out-door stop or station, park, sloping road, out-door playground; heating of greenhouse for plantation or cultivation.
