欧诗朗PE-RT暖通管的原料不但具有合格的蠕变破变曲线。施工相对其它品种方便、快捷，连接形式属于现阶段最可靠的本位互熔热熔连接的形式，管件部位的孔径大于相同规格管材的内径，在系统中因为没有局部缩径的机械连接方式，所以系统流体阻力相对较小
The raw material of oshilang PE-RT heating and ventilation pipe not only has qualified creep rupture curve. Compared with other varieties of construction, the construction is convenient and fast, and the connection form is the most reliable form of standard mutual fusion hot-melt connection at present. The hole diameter of pipe fittings is larger than the inner diameter of pipes of the same specification. In the system, because there is no mechanical connection mode of local reduction, the system fluid resistance is relatively small
