♦ 較強(qiáng)的耐腐蝕性
♦ Stronger corrosion resistance
聚乙烯為惰性材料,除少數(shù)強(qiáng)氧化劑外,可耐多種化學(xué)侵蝕,無電化學(xué)腐蝕,無需做防腐層。
PE belongs to inert material, and it can resist erosion of lots of chemical substances except few strong oxidants. It has no electrochemical corrosion and requires no corrosion resistance layer.
♦ 的韌性
♦ Unrivalled tenacity
聚乙烯燃?xì)夤芸嫌械娜犴g性,當(dāng)?shù)厮慊虻卣鸢l(fā)生時(shí),能隨之產(chǎn)生一定程度的變形而不致斷裂,避免燃?xì)庑孤强沟卣鹦詢?yōu)異的管道。
PE gas pipe features excellent tenacity. In case of differential settlement or earthquake, it can deform to a certain extent accordingly, thus avoiding fracture and gas leakage, so it has excellent earthquake resistance.
♦ 高抵抗刮痕的能力
♦ High scratch resistance
抗刮痕能力使之適用于非挖管道的鋪設(shè)和作為承插管插入舊管道中實(shí)現(xiàn)舊管網(wǎng)修復(fù)。
Scratch resistance makes it suit laying of trenchless pipe and be used as socket pipe to be inserted into old pipe to have old piping network repaired.
♦ 的抗應(yīng)力開裂性
♦ Excellent stress-cracking resistance
聚乙烯管的抗應(yīng)力開裂性能優(yōu)于鋼管,在工程應(yīng)用中可以大小減少管道的泄漏和爆管幾率,增加燃?xì)廨斔偷陌踩浴?/span>
Stress-cracking resistance of PE pipe is better than that of steel pipe. PE pipe can reduce pipe leakage and explosion probability and increase gas transportation safety.
♦ 長久的使用價(jià)值
♦ Long-term service
聚乙烯管材的環(huán)向抗拉強(qiáng)度已被長期靜液壓實(shí)驗(yàn)所證實(shí),使用壽命長。地埋管在-20℃-40℃溫度范圍內(nèi)安全使用50年以上。
Circular tensile strength of PE pipe has been confirmed by long-term hydrostatic test. PE pipe has long serve life, and it can be safely used for more than 50 years when buried at the temperature of -20°C to 40°C.
♦ 較大的輸送流量
♦ Larger flow rate
管壁平滑,能提高介質(zhì)流速,增大流量,與相同的金屬管道相比,可輸送更大的流量,節(jié)省動(dòng)力消耗。
Smooth pipe wall of PE pipe can enhance flow speed of medium and enlarge flow amount. Compared with the same metal pipe, PE pipe can transmit larger flow and save dynamic consumption.
♦ 顯著地經(jīng)濟(jì)效益
♦ Remarkable economic benefits
成本低,投資少,與金屬管道相比,可減少工程綜合投資1/3左右,可盤卷的小口徑管材,可進(jìn)一步降低工程造價(jià)。
The cost and investment are low. Compared with metal pipe, it can reduce overall engineering investment by 1/3. Coiled small-diameter pipe can further reduce engineering cost.
♦ 方便的施工性能
♦ Convenient construction
管道質(zhì)輕,同體積PE材料僅是鋼的1/8,易搬運(yùn),易彎曲,焊接工藝簡單,土方量少,施工速度快捷。
