聚乙烯夾克管
聚乙烯外套管采用高密度聚乙烯材料制成，具有*的機械強度和優(yōu)良的耐腐蝕性能，可以保護管材在運輸、安裝及使用過程中避免因外界因素而造成的破壞。
制造外套管應添加抗氧劑、紫外線穩(wěn)定劑和碳黑等。

、說 明 A.聚乙烯管易老化，如露天存放宜用篷布等物遮蓋，堆放處應遠離高熱源和火源，制成保溫管后，禁止暴曬、驟冷，否則聚乙烯管易開裂，影響產(chǎn)品性能和使用壽命。 B.運輸和穿管過程中，應避免野蠻裝卸，掛鉤過細、過硬、用力過猛，否則易造成聚乙烯管摔壞、劃傷或撕裂。 C.管材壁厚可調(diào)整，壁厚、顏色可按用戶要求生產(chǎn)，因管材壁厚不同，保溫層厚度為約數(shù)，應按實際厚度計算。 D.與管材配套的支架、塑料塞、兩頭法蘭盤，焊條、焊槍、熱縮帶等齊全。 E.表中的允許偏差是按CJ/114-2000行業(yè)標準制定的。 計算公式為：外徑≤400mm時，上下偏差之和=0.1×公稱壁厚+0.2 外徑≥400mm時，上下偏差之和=0.15×公稱壁厚+0.2 |
