Yakha njani inkqubo yemibhobho yeHDPE engavuziyo?

Kwiiprojekthi zothutho lwangoku lwamanzi, ukusebenza kwe Umbhobho we-HDPE kunye nezixhobo ixhomekeke 50% kumgangatho wodibaniso. Njengomboneleli okhokelayo wehlabathi wezisombululo zenkqubo yemibhobho ye-HDPE, Siphengulula kwiitekhnoloji ezintathu ezingundoqo zoqhagamshelwano ukukunceda ukuba wakhe inkqubo yemibhobho yeHDPE ekhuselekileyo nevuzayo..

Ekuqaleni. Kutheni itekhnoloji yoqhagamshelo lubomi benkqubo ye-HDPE?

Nangona i-HDPE (i-polyethylene ephezulu yoxinaniso) umbhobho kunye nezifakelo zinokuguquguquka okugqwesileyo, ukuba inkqubo yoqhagamshelwano ayifanelekanga, iya kukhokelela ku:

Ukugxininiswa koxinzelelo kwi-interface kukhokelela kumngcipheko wokuqhuma kwetyhubhu

Ukuvuza kweMicroscopic kubangela ilahleko engumndilili yonyaka 3% ukuya 5% ye medium

Ukutshintsha kokutshintsha kobushushu kukhokelela ekungaphumelelini ngokubanzi kwenkqubo yombhobho

Ukusetyenziswa kweskimu soqhagamshelwano lwezenzululwazi kunokufikelela:

Amandla adibeneyo ≥ 90% ngamandla omzimba wombhobho

50 iminyaka ubomi benkonzo kunye nokuvuza zero

Nciphisa iindleko zokulondoloza ngaphezulu 30%

Isibini, ubunzulu betekhnoloji ezintathu zonxibelelwano oluqhelekileyo

1. Impundu Fusion

Imeko yesicelo

Idayimitha enkulu yombhobho ongundoqo ongaphezulu kwe-DN90 (unikezelo lwamanzi/umbhobho werhasi/wamashishini)

Icandelo elinomgca umgama omde wobeka

Inqaku lobugcisa

Ukudityaniswa kwenqanaba lemolekyuli: Ngokusebenzisa 220±5℃ ulawulo oluchanekileyo lobushushu, unxibelelwano oludityanisiweyo lwe-polyethylene amatyathanga emolekyuli angena kwelinye

Inkqubo enezigaba ezine:

  1. Phelisa ukugaya (uburhabaxa Ra≤0.01mm)

  2. Uqhagamshelwano lwepleyiti yokufudumeza (uxinzelelo 0.15MPa)

  3. Inqanaba lokufunxa ubushushu (ixesha elibalwe ngokobunzima bodonga)

  4. Guqula i-butt joint (Uxinzelelo olubambe ukupholisa ukuya ngaphantsi kwe-50 ℃)

Ukuthelekiswa kweenzuzo

2. Umbane

DN20-DN315 small and medium pipe diameter

Complex space work (pipe gallery/crossing structure)

Smart upgrade solutions

Our fourth generation fusion pipe fitting integration:

Chip-level temperature monitoring: real-time tracking of 10 temperature measurement points

Self-compensating pressure system: Automatically adjusts the expansion margin

Qr code traceability: Scan code to obtain welding parameter history

Operation five-step method:

1. Scrape off the oxide layer (depth 0.1-0.2mm)

2. Install positioning fixture (deviation < 1°)

3. Scan code to activate welder parameters

4. Intelligent step heating (39V±2V)

5. Cool naturally for 120 minutes

Data verification criteria:

Flanging height ≥ 10% of pipe wall thickness

The resistance wire is fully embedded in the melt

Cooling shrinkage < 0.3%

3. Mechanical Joints

Applicable scenarios

Temporary works (construction site/emergency repair)

Dissimilar material transition (HDPE with steel/cast iron pipe)

Innovative seal construction

Triple locking system:

  1. Stainless steel clamp (304/316L optional)

  2. EPDM wedge seal ring (temperature -40℃~120℃)

  3. Anti-slip tooth design (anti-axial displacement)

Installation precautions

The bolts should be tightened three times in diagonal order

Final torque value: DN100 pipe fitting 35N·m±10%

The elasticity of the seal ring should be tested annually.
