The installation of home decoration pipeline directly affects the later water and drinking problems. Today, the pipe manufacturer Jie Erkang building materials Xiaobian made a detailed introduction to the pipeline construction process installation process. The installation process of each pipeline is different, such as PPR water supply pipe installation process, PVC drain pipe installation process, etc. This period HDPE pipe manufacturers and you first make a summary of pipe installation.
First, the preparation before construction
1. Familiar with the layout of the room, especially the distribution position of the kitchen and toilet, the drainage position, the geometric size of common sanitary ware, familiar with the situation of water and gas equipment, performance, interface specifications, safety and transfer method.
2. Four inspections before construction:
(1) Check whether the materials and accessories sent are the same as the construction content and whether the quality meets the requirements.
(2) Check whether the inlet pipe and drain pipe of the bedroom are smooth, and whether the water meter and valve are intact.
(3) Check whether the tools are in line with the construction requirements.
(4) Check whether there is a power supply requirement for disinfecting purifiers above the toilet.
Two, pipeline construction process
A. (positioning and marking) -- B. (slotting) -- C. (blanking, laying and fixing) -- D. (Pressurization test) -- E. (Air wall) -- F. (After painting, wash pipes, install faucets and accessories) -- G. (Water connection test)
1. Positioning and marking: refers to the positioning of water and gas equipment such as sanitary ware, water heater, washing machine, sink, gas stove, etc., to determine the location of pipeline terminal. And according to the position of the pipe port on the wall, the ground to draw the pipeline line.
2, home decoration pipeline are typically used in the form of dark compress (except gas pipeline) After the line open pipe groove, the width and depth of the pipeline is typically 1.5 times the diameter of the pipe.
3, after slotting according to the required length of the material, pipe cutting must be carried out by mechanical processing. The laying must comply with the principle of "horizontal and vertical". The wall pipe can be fixed by pipe clamp, and the ground pipe can be fixed by cement.
4. Pressurization test (see special process requirements for rear pressurization test)
5. After the pressurization test is qualified, do the cold and hot water test first to check whether there is leakage, and then seal the pipe groove with cement mortar (slightly lower than the wall plane). After cement mortar sealing, we must meet the "no empty" standard.
6, after the end of the painting work, remove the dull head, install faucets, valves and additional accessories.
7, for water test, check whether the faucet, valve opening is flexible, whether the water is smooth, whether the connection leakage. The tub is at the service port. Leave a sign.
8, toilet floor and surrounding wall 300mm below must be waterproof treatment, bathroom wall waterproof layer shall not be less than 1800mm, if the structure of special circumstances, the corner must be arc waterproof treatment. (waterproof material common number polyurethane waterproof coating)
