PPR Pipes Easy Construction And Long Service Life

2018-11-15

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.

Ba chóir suiteáil taobh istigh de phíopa PPR a chur i gcrích tar éis an maisiú sibhialta a chríochnú, agus an t-ithir á shuiteáil roimh an bpoll ceart nó i gcásáil leabaithe. Ba cheart an phíblíne tríd an urlár a shocrú nuair ba chóir go mbeadh na gabhálais cruach, na sonraíochtaí casála níos mó ná an trastomhas PPR dhá, 50mm os cionn na talún. Ba chóir balla píopa PPR a shocrú nuair a bhíonn an t-ábhar cruach, an dá cheann agus an leibhéal balla.

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.

Such as easy to find and repair the pipeline, with the PPR Pipes at the same time laying a pipe with anti-corrosion wire (available rubber metal wire), so that after the metal pipe detector to facilitate the use of metal pipe detector to determine the location of PPR pipe, easy maintenance. Buried laying PPR pipes should be below the depth of the local permafrost. Through the road or structure, should be added steel casing, casing length or width of the structure plus 1m, casing diameter should be larger than the PPR pipe diameter two.

Níl na tréithe ag píopaí PPR ar a lán de na píopaí miotail, tá sé ina bhalla píopa réidh, neamh-scálaithe, atá creimeadh-resistant, a chosc go héifeachtach an t-uisce sa phíblíne sa truailliú tánaisteach, agus go hálainn. Áise tógála, dlús a chur leis an luas tógála. Is féidir le saolré píopaí PPR fad cúig huaire teacht ar shaol píopa ghalbhánuithe, go bunúsach suas go dtí saor ó chothabháil, ag laghdú go mór costais oibriúcháin a chothabháil. Dá bhrí sin, úsáidfear píopa PPR sa tionscadal soláthair uisce amach anseo.

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, the surface of the pipe and joints to ensure clean, smooth, no oil.

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, chun an t-am teasa a chríochnú, an píblíne go réidh agus a bhrú go cothrom isteach sna hailt, ionas go mbeidh a n-teaglaim láidir agus foirfe.

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, toisc go bhfuil an t-ábhar solas, solúbtha, is féidir gach táthú a dhéanamh ar an mbord, is féidir leis an buntáiste seo sábháil uaireanta an duine.

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%.
