Precautions for using IFAN pipes

Specifications of PP-R pipes

Usually, we often hear about 4-points and 6-points pipes. 20mm outside the 4-points pipe and 25mm outside the 6-points pipe. 6-points pipe has a larger water flow than 4-points pipe in actual use. Main line pipeline more 6 points, branch line pipeline more 4 pipes. Water flow is not the greater the better, otherwise it will cause water wastage of the elephant.

Laying of PP-R pipes

To choose the actual situation of the plumbing is to go to the top or go to the ground. The following are some advantages and disadvantages of comparison.

Go to the top: leakage problems found early, but also convenient to do the ground water in the bathroom, once there is a leak, not to affect the neighbors downstairs; but also the problem of laborious construction, as well as maintenance may need to remove the ceiling.

Go to the ground: save work, in the work and pipe to save a sum of money; occurrence of leaks is relatively difficult to find, and in the case of circuit also go to the ground may cause circuit failure; maintenance is not easy to find the leak, may cause extensive damage; also easy to cause disputes in the neighborhood.

PP-R pipe connection

PP-R water pipes are connected by hot melt, the suitable temperature is around 260 degrees, the temperature is too high for the material to become too thin and soft, affecting the quality; the hot melt welding machine should pay attention to the maintenance of the die, check before the hot melt, the aging of the die will also bring hidden problems; the parameters of the die also need to pay attention to, the size of many domestic die is generally smaller than the standard die, to communicate with the decoration team in advance on the standard of the pipe.

Acceptance of the water line

The water pipe pressure test is one of the common methods used to determine whether the water pipe connection is reliable, the water pipe connection is not good after the leakage and other conditions will occur, leaving hidden dangers to the home water; hot and cold water too close to each other may cause extrusion problems. So be sure to keep the distance. You can take a ruler to measure, the pipe diameter spacing of 15cm is qualified, the error to ensure that within 0.1cm; wire casing and water pipes with the slot, the water pipe leakage is easy to cause the wire moisture, short circuit, and even produce leakage and other dangerous situations. According to standard specifications, plumbing must be placed in different slots, the distance of 15cm, but also pay attention to the measurement; if not necessary to try to reduce the water pipe joints. Two cut water pipes try to reduce the head by elbow direct connection. When accepting, pay attention to ensure that the two water pipes are directly connected through the elbow, and do not have extra joints.
