HDPE Yeeb Nkab & PVC Yeeb Nkab Hauv Kev Txhaj Tshuaj thiab Streamline System

Hauv kev lag luam xws li roj thiab roj, tshuaj, thiab cov dej haus, kev xaiv ntawm cov kav dej ncaj qha cuam tshuam rau kev ua haujlwm thiab cov nqi ua haujlwm ntev. HDPE yeeb nkab (high-density polyethylene yeeb nkab) thiab PVC yeeb nkab (polyvinyl chloride yeeb nkab) ua lub luag haujlwm tseem ceeb hauv Kev Txhaj Tshuaj thiab Flowlines ua cov neeg nqa khoom tseem ceeb, ua tsaug rau lawv cov txiaj ntsig kev ua tau zoo tshwj xeeb. Tsab xov xwm no yuav nkag mus rau hauv cov yam ntxwv ntawm ob qho tib si thiab muab cov lus qhia xaiv rau cov ntawv thov kev ua haujlwm los pab koj ua kom zoo dua koj qhov project tsim.

Kev ua tau zoo thiab cov ntawv thov zoo li qub ntawm HDPE yeeb nkab

1. Zoo heev tshuaj tsis kam

HDPE yeeb nkab muaj ib tug ntom molecular qauv thiab yuav tiv taus lub yaig ntawm muaj zog acids, muaj zog alkalis thiab ib tug ntau yam ntawm cov organic kuab tshuaj. Nyob rau hauv tshuaj txhaj tshuaj, nws yog feem ntau siv los thauj corrosive media (xws li acid thiab alkali tov, tshuaj neeg sawv cev), nrog ib tug kev pab cuam lub neej ntawm ntau tshaj tshaj 50 years, heev txo txij nkawm nqi vim corrosion xau.

2. High saj zawg zog thiab cuam tshuam tsis kam

HDPE yeeb nkab muaj ib tug elongation ntawm so ntawm dhau 350% thiab yuav hloov mus rau deformation tshwm sim los ntawm geological subsidence los yog kub hloov nyob rau hauv oilfield streamlined systems, tshwj xeeb tshaj yog haum rau complex av scenarios xws li subsea pipelines thiab trenchless yeeb nkab jacking kev tsim kho. For example, ib tug DN400 HDPE yeeb nkab tau siv nyob rau hauv ib tug offshore oilfield project thiab ntse tiv thaiv cov dej ntws cuam tshuam nyob rau hauv ib tug cua daj cua dub ntawm quab yuam 12.

3. Tsawg kev sib txhuam coefficient thiab lub zog txuag kev ua tau zoo

Puab phab ntsa smoothness ntawm HDPE (roughness coefficient 0.009) yog qhov zoo dua li cov yeeb nkab hlau thiab tuaj yeem txo cov kev siv hluav taws xob ntau dua li 30% hauv cov dej ntev. Ib qho kev sib piv ntawm ib txoj haujlwm xa dej hauv nroog qhia tau hais tias HDPE yeeb nkab noj 25% less electricity than traditional steel pipes at the same flow rate, saving over a million yuan in operating costs annually.

Typical application cases

– Water injection systems in oil and gas fields: High pressure resistance (PN16 grade) and anti-scaling properties extend the lifespan of water injection Wells

– Industrial wastewater reinjection pipeline: Resistant to hydrogen sulfide corrosion and prevents seepage contamination

– Geothermal energy transmission: Stability at -60 ° C to 60 °C

Core characteristics and application areas of PVC pipes

1. Economic and lightweight advantages

PVC raw material costs about 20% less than HDPE and has a density of only 1.4g/cm³, making it easy to install in low-voltage streamline systems. For example, Kev siv Φ110mm PVC yeeb nkab hauv kev ua liaj ua teb irrigation tej yaam num nce qhov ua tau zoo ntawm phau ntawv nteg los ntawm 40% thiab tshwj xeeb tshaj yog tsim nyog rau cov phiaj xwm me thiab nruab nrab nrog cov peev nyiaj tsawg.

2. Zoo heev huab cua tsis kam thiab rwb thaiv tsev ua tau zoo

PVC yeeb nkab nrog ntxiv UV stabilizers tuaj yeem siv sab nraum zoov rau lub sijhawm ntev thiab tau siv dav hauv cov tshuab cua hauv cov nroj tsuag tshuaj lom neeg thiab ua sheaths rau cov kab hluav taws xob. Cov kua qaub pos huab tso tawm yeeb nkab ntawm cov tshuaj lom neeg cog siv SCH80 PVC thiab tau ua haujlwm tsis tu ncua rau 8 xyoo tsis muaj kev laus lossis tawg.

3. Cov xwm txheej xav tau kev txhawb nqa cov qauv txhav

Lub elastic modulus ntawm PVC yeeb nkab (3000 MPa) yog 10 lub sijhawm ntawm HDPE thiab ua tau zoo dua hauv cov kav dej uas yuav tsum tau tiv taus khoov, xws li cov kav dej hauv chav kuaj, kom tswj tau cov duab ncaj yam tsis tas yuav tsum muaj kev txhawb nqa ntxiv.

Typical application cases

– Kev txhaj tshuaj qis qis siab: thauj cov kua qaub thiab alkali tov nrog cov concentration ntawm ≤30%

– Txias dej ncig raj xa dej: Kaw-voj ncig scenario nrog kev ua haujlwm kub ≤45 °C

– Mine drainage network: Lub teeb yuag tsim txo cov nqi thauj mus los

Kev sib piv ntawm cov ntsiab lus tseem ceeb ntawm HDPE thiab PVC yeeb nkab thiab cov tswv yim xaiv

Selection decision tree

1. Medium characteristics: Transporting highly corrosive fluids → Preferred HDPE; Weak acidic or alkaline environment → Consider PVC for cost reduction

2. Qib siab: Demand ≥PN16→HDPE; ≤PN10→ Comprehensive cost assessment

3. Installation environment: Geologically unstable/trenchless →HDPE flexibility; Fixed bracket exposed →PVC rigid

4. Life cycle: Design over 50 years →HDPE; Short-term projects of 10-20 years →PVC
