熱力管道直埋保溫管 聚乙烯外護(hù)套價(jià)格
高密度聚乙烯外套管
聚乙烯外套管采用高密度聚乙烯材料制成，具有極高的機(jī)械強(qiáng)度和優(yōu)良的耐腐蝕性能，可以保護(hù)管材在運(yùn)輸、安裝及使用過程中避免因外界因素而造成的破壞。
制造外套管應(yīng)添加抗氧劑、紫外線穩(wěn)定劑和碳黑等。
公司擁有廠房面積6000平方米，廠區(qū)配有24m龍門吊兩臺(tái)，車間配有20m行車兩臺(tái)，HDPE夾克管生產(chǎn)線十條，具備年產(chǎn)HDPE夾克管800Km、預(yù)制聚氨酯直埋管400Km、玻璃鋼聚氨酯直埋管300Km、預(yù)制鋼套蒸汽直埋管100Km的生產(chǎn)力。
