PPR Aluminum plastic stable pipe

Longyue PPR aluminum-plastic stable pipe imports the latest composite pipe technical from Germany;it takes the lead in hot water supply,radiator heating,and center-air condition system in domestic market.The pipe add an aluminum alloy on the base of PPR pipe,using macromolecule cement under a high temperature compound the PPR pipe and aluminum alloy.This pipe is the perfect union of metal and plastic pipe but has the hygienic,hermentic of plastic pipe,the rigidity of metal pipe,a much higher intensity,much stable mechanical property at the same time,It also can prevent ultraviolet, the linear expansion ration is 1/5 of the normal PPR pipe which is close to the metal pipe,and the pipe possesses a much higher stability and safety.

Longyue PE-RT under ground heating pipes PE-RT)

PE-RT under ground heating pipes the main mainstream of underground heating radiation 21 century. PPR pipe is forcedly and fragile,shock resistant is comparatively poor,it is not suit for convolute installation under 10?and underground heating system. PB pipe is too fragile it is easy come forth nick when it is been installed and the price for the material is much higher. PE-X B pipe quality is not stable,if the degree of cross liking is not enough the heat-resistant is poor and the oxidation speed comes high. PE-RT heat-conducting property,flexibility,heat-resistant and oxidation-resistant is good enough for using in ender ground heating system.

Longyue Aluminum-plastic PPR pipe (PPR)

Aluminum-plastic PPR pipe integrate all kinds of advantages of PPR pipe and Aluminum-plastic composite.It adults the advanced fusion link. The strength of the link part will not reduce but much higher than the pipe itself, it boost up the capability of the airproof and is easy to installed.It is the new generations of conventional zincification pipes.

Longyue PPR pipe

Prandom Polypropylene(PP-R) is a high strength material that could be used for more than 50 years in hot water.and it also used for cold and hot water pipe system. The product had passed 8760 hours hot stable testing under Static hydraulic pressure Condition and 5000 pipes hot Circulation testing.

Longyue aluminum plastic composite pipe

Longyue (laser welding,overlapped weld)aluminum plastic composite pipes stands at the industry leading place,advanced technical as its elements,scientific quality supervise system as its support,according to GB/T18997.2-2003 and GB/T18997.1-2203 as its production standard.All the production are controlled by computes and the laser check-up.

FR-PPR high performance fiberglass composite pipe

FR-PPR high performance fiberglass composite pipe is three-layer structured. The outer and inner sides are made of PP-R material while the middle layer is made of fiberglass composite material.The inner layer PP-R material ensures hygienic performance of the pipe while the middle layer helps to strengthen pipe and reduce linear expansion coefficient.The outer layer PP-R facilitates hot-malt socket connection between the pipe and the traditional PP-R pipesfeatures high strength,high toughness,high stiffness and low linear expansion coefficient,which fill in the gap for application of ordinary PP-R in vertical pipe,visible installation pipe and hot water pipe ,It is an idea improvement from and useful supplement for PP-R pipe.
