PE-RT管材、管件是以-辛烯共聚物為主要原料，按照CJ/T175-2002生產(chǎn)的耐高溫管道系統(tǒng)。它所用原料具有的分子結(jié)構(gòu)，它以線性乙烯為主鏈，加上可控分支，從而具有良好的耐水壓性能。它的柔軟性好，在施工時(shí)容易彎曲而且不會(huì)變形，耐低溫沖擊性突出，安全衛(wèi)生，熱熔連接，接口可靠，不滲漏，是地板采暖的理想管材。
◆ 重量輕：便于運(yùn)輸和安裝
◆ Low weight: Convenient for transportation and installation
◆ 柔軟性：彎曲模量為550MPa，有良好的柔軟性。PE-RT管道施工時(shí)（特別在冬季），不需要特殊的工具或者加熱就能彎曲，因此加工成本比較低，而且彎曲產(chǎn)生的內(nèi)應(yīng)力比較低，對(duì)管材的使用壽命影響小。同時(shí)因?yàn)楣懿娜彳洠菀坠潭ǎ瑢?duì)固定管材的鐵絲網(wǎng)的要求比較低，可以節(jié)約成本。
◆ Flexibility: Its flexural modulus is 550 MPa, with excellent flexibility. In PE-RT pipe construction (especially in winter), it can be bent without special tools or heating, thus processing cost is relatively low, and the internal stress produced by bending is low as well, producing little influence on service life of the pipe. Besides, as the pipe is flexible and can be fixed easily, with low requirements on wire net for fixing, thus it is able to reduce cost.
◆ 導(dǎo)熱性：導(dǎo)熱系數(shù)為0.40W/m•K，導(dǎo)熱性能良好，適合用做地板采暖管。
◆ Heat conductivity: It has excellent heat conductivity, with heat conductivity coefficient of 0.40 W/m•K, so it is suitable for floor heating pipe.
耐低溫沖擊性：在低溫下仍可保持高彈性。冬季施工時(shí)管材不易受到?jīng)_擊而破裂，增加了施工安排的靈活性。
Low temperature impact resistance: It keeps high elasticity even under low temperature. During winter construction, the pipe is unlikely to be impacted to fracture, thus increasing flexibility for construction arrangement.
◆ 環(huán)保性：可以回收利用，不污染環(huán)境。
◆ Environmental protection performance: It can be recycled, thus it will not pollute the environment.
◆ 加工性能穩(wěn)定：不存在控制交聯(lián)均勻度等問(wèn)題，簡(jiǎn)單的加工工藝使產(chǎn)品具有穩(wěn)定的性能。
◆ Stable processability: It is free of problems like control of crosslinking uniformity, and its simple processing technology enables products to have stable performance.
◆ 長(zhǎng)久使用壽命：具有良好的環(huán)境適應(yīng)性，耐化學(xué)腐蝕性好，管道正常使用壽命在50年以上。
◆ Long service life: It has good environment adaptability and chemical resistance, thus the normal service life is above 50 years.
◆ 可靠的連接方式：可以熱熔連接，從而形成封閉的防滲系統(tǒng)，連接方便牢固。
◆ Reliable connection: Hot melting connection can be adopted, which is easy and firm, to form a completely sealed anti-seepage system.
◆ 衛(wèi)生性能：無(wú)毒、無(wú)味、衛(wèi)生性能好。
