Quam ut install HDPE Gas Pipe Recte??

Polyethylene (HDPE) gas pipe materia electionis factus est systemata gas traditio propter excellentem observantiam et oeconomiam. PE ducens gas pipeline ut in Sina producentis, non solum providere summus qualitas products quae signa gentium conveniunt, sed etiam providere OEM (originali apparatu faciens) et ODM' (original design faciens) officia nostris clientibus ut diversae necessitates mercati globalis occurrant.

Primum, core commoda HDPE Gas Pipe:

1. Corrosio resistentiae et longae vitae

   PE materia naturalem resistentiam habet ad corrosionem chemicam et corrosionem electrochemicam, maxime apta infectum, acid-alcali solo environment. Comparari cum traditional fistulae metallicae, obsequium vitae possit plus 50 annos, et conservatio sumptus potest reduci per plura 60%.

2. Princeps flexibilitate et impulsum resistentia

Elongatio ad ortum PE pipelini excedit 350%, quae efficaciter resistere potest per constitutionem compositione vel terrae motus deformatio. Effectus adhuc stabilis est sub extrema temperie -60℃ ad 40℃.

3. Leve et opportunum constructione

Densitas solum 1/8 de ferro tibia, et translationem ac institutionem efficientiam signanter emendavit. Usus technologiae technologiae calidae liquefaciendi vel electricae fusionis, non opus est universa armorum welding, constructione celeritas augetur 30%-50%.

4. Environmental tutela et salus

Nullae substantiae noxiae emittuntur in processu productionis, et 100% recyclable. Murus interior pipeline levis est, in Gas fluxus resistentia est parva, et periculo lacus est valde humilis, quae in EU EN 1555 et Sinis GB 15558 signa.

Secundus, Processus instruitur HDPE Gas Pipe

1. Praeparatio ante institutionem

Design planning: Designa directionem pipeline secundum gas fluxum, pressura gradu (ut SDR11 / SDR17) ac locorum conditionibus, ne impedimenta sub terra, et ut profunditas infossa sit ≥ 0.8m (via) aut ≥ 0.6m (sidewalk).

Materia acceptatio: speciem sisto pipeline (non exasperat, bullae), speciem certificatorium (comprehendo rudis materia liquescens index, oxidatio inductio tempore test fama), et sampling for hydrostatic vires test (80/165h).

Curatores disciplina: Constructio personarum opus est ut operatio certificatorium pipeline teneretur, dominaberis calidum conflandum apparatus temperatus imperium (220±10℃) et pressura parametri (calor effusio pressura 0.15MPa, frigus pressura 0.02MPa).

2. Fossa effossio et curatio fundamenti

Cum mechanica FOSSIO adhibetur, 20cm manual cleaning layer is reserved at the bottom of the trench to ensure the base is smooth.

Lay 10cm thick sand cushion layer on rock or hard ground to prevent pipe scratches.

3. Pipe laying and connection

A.Hot melt butt (DN≥90mm) :

  1. Milling the end face to flat, the amount of misalignment < 10% murus crassitudine.

  2. The heating plate temperature is set at 210℃-230℃, and the heating time is calculated according to the wall thickness ×10 seconds /mm.

  3. Maintain constant pressure at the endothermic stage, switch time ≤5 seconds, cooling time ≥ wall thickness ×1min/mm.

B.Electric fusion connection (DN≤315mm) :

  1. Scrape off the oxide layer and mark the insertion depth clearly.

  2. Set the voltage (usually 36V-48V) according to the resistance value of the fuse sleeve, and the welding time is automatically calibrated.

Quality inspection: the flanging height should reach 1/3 of the wall thickness of the tube, and the electric melting observation hole should be pushed out.

4. Pressure test and backfill

The strength test (1.5 temporibus operantes pressura, 4h pressure regulation) and the tightness test (1.15 temporibus operantes pressura, 24h pressure drop ≤1%) are carried out in sections.

Backfill using lamination compaction method, each layer thickness ≤20cm, the initial backfill using fine sand to protect the pipeline.

The scientific installation of Polyethylene (HDPE) Gas Pipe is the core link to ensure gas safety, and choosing a Chinese pipes and fittings manufacturer with leading technology can better obtain the triple advantages of cost, quality and service.
