TPEP防腐鋼管--外TPEP內熔結環氧防腐鋼管【勝倉管業 袁經理18903175665  QQ1623133043】是在外單層聚乙烯內環氧復合鋼管的基礎上升級換代產品，是目前埋地長輸管線zui先進的鋼管防腐形式。公司自主開發的第四代大口徑管道新型防腐生產線，外壁采用熱熔結纏繞工藝底層環氧樹脂、中間層膠黏劑、外層聚乙烯形成三層結構的防腐層，內壁采用熱噴涂環氧粉末防腐方式，將粉末經高溫加熱熔結后均勻地涂敷在管體表面上，形成鋼塑合金層，簡稱TPEP鋼管，（T，三層英文Three的首寫字母，PE指聚乙烯，EP指環氧樹脂）。極大提高了涂層附著力及涂層厚度，增強了耐磕碰，耐腐蝕的能力。該產品于2009年獲取國家實用新型專利。2010年獲得國家火炬項目。TPEP鋼管填補了國內鋼管zui佳防腐的空白，價格與單層聚乙烯內熔結環氧復合鋼管相差無幾，耐腐蝕能力提高了3-5倍。

TPEP anticorrosive steel pipe - external TPEP internal melting epoxy anticorrosive steel pipe is an upgrade product on the basis of external monolayer polyethylene internal epoxy composite steel pipe. It is the advanced anticorrosive form of steel pipe in Zui of buried long distance pipeline. The fourth generation of large diameter pipeline production line is developed independently by the company. The exterior wall of the pipeline is made of three layers of anti-corrosive coating made of epoxy resin, adhesive and polyethylene. The interior wall of the pipeline is made of heat-sprayed epoxy powder. The powder is evenly coated on the pipe after being heated and melted at high temperature. On the surface, a steel-plastic alloy layer, referred to as TPEP steel pipe, (T, three English Three initials, PE refers to polyethylene, EP refers to epoxy resin). The adhesion and coating thickness of the coating are greatly improved, and the resistance to bumping and corrosion resistance is enhanced. The product acquired the national utility model patent in 2009. In 2010, he won the national Torch Program. TPEP steel pipe fills the domestic steel pipe Zui good anticorrosion blank, the price and single-layer polyethylene internal melting epoxy composite pipe almost the same, corrosion resistance increased by 3-5 times.
