Electric Fusion External Thread Direct Fitting (S50*1-1/2F)

A: Yes. HOPE material itself has excellent flexibility with an elongation rate of over 350%. The joint after electrofusion connection is a flexible connection rather than a rigid fixation, which can adapt to a certain degree of foundation settlement and pipeline displacement-this flexibility is equally reliable for pex pipes and fittings, air conditioner copper pipe, and even moonshine transfer lines. When laid underground, combined with the flexible characteristics of HOPE pipes and pex pipes and fittings, it can effectively resist the impact caused by soil pressure and uneven foundation settlement, prevent joint fracture or leakage. Whether it is used for air conditioner copper pipe routing in underground utility trenches or pex pipes and fittings in farmland irrigation systems, it performs stably, and is particularly suitable for scenarios with high settlement risks such as coastal soft soil foundations and farmland, including areas where moonshine transportation pipelines are laid.

A: The rated working pressure of this product is 1.6MPa, which complies with the national standard GB/T 19809-2020. It can meet the pressure requirements of most civil and industrial low-pressure pipeline systems, including those using pex pipes and fittings for residential water supply, air conditioner copper pipe for HVAC circulation, and low-pressure moonshine transfer pipelines. When used in high-pressure scenarios (such as secondary water supply in high-rise buildings with pex pipes and fittings or high-pressure air conditioner copper pipe systems), it is necessary to confirm the system pressure in advance and select a suitable product with the corresponding high-pressure rating. During use, please note that the working pressure must not exceed the rated value, regardless of whether it is matched with pex pipes and fittings, air conditioner copper pipe, or moonshine pipelines, to avoid joint damage due to excessive pressure.

A: There are two main testing methods, which are applicable to all scenarios including pex pipes and fittings, air conditioner copper pipe, and moonshine transfer pipelines. First, visual inspection: after welding and cooling, check whether there is molten material overflow at the joint. Uniform overflow without bubbles or cracks indicates that the welding is basically qualified, which is a key step for ensuring leakage-free connection of air conditioner copper pipe and pex pipes and fittings. Second, pressure test: after the pipeline system is filled with water (or the medium transported, such as moonshine for relevant pipelines), close the valve to conduct a static pressure test. The test pressure shall be 1.5 times the rated working pressure, and the pressure shall be maintained for 30 minutes. If the pressure drop does not exceed 0.05MPa and there is no leakage at the joint, it is qualified. Please note that overpressure testing is strictly prohibited during pressure detection, no matter it is for pex pipes and fittings, air conditioner copper pipe, or moonshine pipelines, to avoid damage to pipes, fittings and the transported medium.
