鋼塑管
詳細介紹:

  石油天然氣管道涂層復合鋼管,是國內新近發展的一種新型管道材料,采用內外均有涂塑保護層,中間位增強焊接鋼管或無縫承壓鋼管的復合結構,克服了鋼管本身存在的易生銹、腐蝕、高污染及塑料管強度低、易變形的缺陷,整合了鋼管和塑料產品的共同優點,屬于國家推廣使用的環保產品。石油天然氣用復合鋼管的材質均選用國標產品,涂敷改良后的特制環氧樹脂粉末。其工藝技術專門針對石油天然氣管道特殊的環境條件研發,產品符合SY/T0315-2005和CJ/T120-2008相關標準,具有耐腐蝕、使用壽命長、有效增強安全性等諸多優勢,是替代傳統管材的理想產品。

塑復合鋼管的性能特點是1、承壓高機械性能優異:涂塑鋼管延續了鋼管的優點,其機械強度和高承壓性能好,對沖擊、彎曲等外界因素影響具有很強的承受能力,可以承受苛刻的使用條件,安全性高。2、耐化學腐蝕性能突出,系統整體防腐效果好:涂塑鋼管的塑料具有很強的耐酸堿性、乃土壤腐蝕及耐候性能,適用于石油天然氣管道以及其他腐蝕性介質的流體。產品可帶法蘭涂裝,三通、彎頭等各種管件均經過內外涂塑防腐處理,確保整體管路的防腐效果,使用壽命可數倍于普通鋼管。3、涂層附著力強:涂塑鋼管采用物理深度處理工藝,前處理達到Sa2.5標準,錨紋深度在40μm~100μm范圍內,選用環氧樹脂粉末涂料或添加極性基因,采用微電腦全自動預熱控制,自動化生產,科學合理的工藝及先進的設備保證了涂層質量,其附著力明顯高于國家標準。4、不結瘤、不結垢、流體阻力。和克茕摴軆韧獗砻嫱繉又旅,具有潤滑不結瘤、結垢,磨阻系數和粗糙系數均小于普通鋼管,同管徑流通能力可提高15-30%,節約輸送動力15%,屬于經濟環保性價比較高的產品。5、耐溫性能高:具有良好的耐溫性能、涂層復合管可根據輸送介質溫度不同,選用石油天然氣專用環氧樹脂或聚乙烯材料,輸送介質溫度高可達260℃。6、安裝方便快捷:重量輕、運輸、安裝方便,涂層復合鋼管不需考慮鋼管腐蝕余量,根據壓力需要選用壁薄的鋼管(可根據設計要求選用薄壁焊管或無縫鋼管),可選用卡箍式快速接頭、法蘭等連接方式。
