ท่อ PPR ก่อสร้างง่ายและอายุการใช้งานนาน


PPR Pipes laying can be divided into the installation of equipment, dark equipment laying, overhead laying and laying and other laying methods. As the PPR Pipes by the environment and the impact of medium temperature changes, it is appropriate to use the dark, the construction should be with the construction, structure, electrical and other professional closely with each other, coordinate each other, do a good job reservation, burial work, and take appropriate protection Measures. The wall should be reserved for the pipeline, the pipeline laying a good pressure should be filled around the tube at least 20mm thick rock wool and other soft materials to prevent the condensation of the pipeline or due to temperature changes in the pipeline deformation and destruction of the wall. Dark pipe should be completed in the civil and decoration after the completion of the second system test pressure, ruled out due to civil or decorative damage caused by the pipeline, after acceptance can be put into use.

Indoor installation of PPR pipe, should be carried out after the completion of the civil decoration, with the installation of the soil before the correct hole or embedded casing. Pipeline through the floor should be set when the steel casing, casing specifications should be larger than the PPR diameter two, 50mm above the ground. PPR pipe wall should be set when the steel casing, both ends and the wall level.

Buried laying PPR pipes. Trench ditch should be tampered after the ditch at the end of the ditch at the end there should be no mud and prominent hard objects, if there is a hard material should be laid in the ditch at the end of 100mm thick sand cushion, sprinkler compaction, after the completion of laying pipes. Such as buried pipes in the metal pipe fittings, pipe fittings should be done anti-corrosion treatment. Pipeline laying must be carried out according to GB50242-2002 standard water pressure test, qualified before backfilling. Trench backfill, the pipe on both sides of the pipe and the top 200mm within the scope of the use of sand or less than 12mm diameter of the soil does not contain hard objects backfill, gently tampeen and then the upper diameter of 30mm below the soft soil backfill Step by step.

เช่นง่ายต่อการค้นหาและซ่อมแซมท่อด้วยท่อ PPR ในเวลาเดียวกันวางท่อด้วยลวดป้องกันการกัดกร่อน (ลวดโลหะยางที่มีอยู่) ดังนั้นหลังจากที่เครื่องตรวจจับท่อโลหะเพื่อความสะดวกในการใช้เครื่องตรวจจับท่อโลหะเพื่อตรวจสอบ ตำแหน่งของท่อ PPR บำรุงรักษาง่าย การวางท่อพีพีอาร์ที่ถูกฝังอยู่ควรต่ำกว่าระดับความลึกของรูฟอรอฟรอสต์ในพื้นที่ ผ่านถนนหรือโครงสร้างควรเพิ่มท่อเหล็กความยาวหรือความกว้างของโครงสร้างบวก 1m เส้นผ่าศูนย์กลางท่อควรมีขนาดใหญ่กว่าเส้นผ่าศูนย์กลางท่อ PPR สอง

PPR pipe has a lot of metal pipes do not have the characteristics, it is corrosion-resistant, non-scaling, smooth pipe wall, effectively prevent the water in the pipeline in the secondary pollution, and beautiful. Construction convenience, speed up the construction speed. PPR Pipes long life, can reach five times the life of galvanized pipe, basically up to the maintenance-free, greatly reducing the maintenance of operating costs. Therefore, PPR pipe in the future water supply project will be more widely used.

For PPR pipe installation, we can not be so professional, but understand the most basic welding steps can help us better check whether the installation of water pipes in line with the norms, so that the safe use of water pipes can be guaranteed.

1, พื้นผิวของท่อและข้อต่อเพื่อให้แน่ใจว่าสะอาดเรียบไม่มีน้ำมัน

2, need to mark in the pipeline to try to insert. (Equal to the fitting depth of the joint).

3, the entire embedded to carry out the depth of heating, including pipes and joints, are carried out in the welding tool.

4, to complete the heating time, the pipeline smoothly and evenly pushed into the joints, so that their combination of solid and perfect.

5, in the pipe joint welding within a few seconds, you can adjust the connector position.

6, in a short period of time, the connector can be with the load.

7, with a self-adjusting hot-melt welding machine to pipe and pipe welded together, the temperature is 260 ° C.

8, the machine connected to the power (220v) and wait for a moment, when the green light flashing that has reached the welding temperature, began to work.

9 เนื่องจากวัสดุที่มีน้ำหนักเบามีความยืดหยุ่นการเชื่อมทั้งหมดสามารถดำเนินการบนโต๊ะประโยชน์นี้สามารถประหยัดชั่วโมงแรงงาน

10, sometimes in the wall to make some connections, we should pay attention to the joint location in the operating space, you can operate. If the ambient temperature is below 5 ° C, the heating time is increased by 50%.
