PSP steel-plastic composite pipe is a new type of metal plastic composite pipe, which is formed by rolling steel strips into steel pipes and subjected to argon arc butt welding. It has plastic layers inside and outside, and a multi-layer composite structure with reinforced welded steel pipes in the middle. It overcomes the defects of easy corrosion, pollution, bulkiness, short service life, low strength, large expansion, and easy deformation of plastic pipes, as well as the common advantages of steel pipes and plastic pipes, For example, it has good oxygen isolation, high rigidity and strength, and is easy to detect when buried.

  The PSP steel plastic composite pipe uses advanced and mature "online forming process" to shape the steel pipe and plastic pipe simultaneously, with low internal stress. PSP steel plastic composite pipe has sub arc welding process forming, welding joints, no protruding plastic composite pipe, and no stress cracking points. Unique production process, reliable and fast connection; Improve surface corrosion and create a beautiful and elegant appearance; Outer pipe wall thickness, reasonable design; Lined with plastic pipes to ensure a reasonable wall thickness through diameter; Save energy and protect the environment, with outstanding development potential.

  PSP steel plastic composite pipes are suitable for public buildings and residential water supply pipelines, and can be widely used in fields such as building water supply engineering, petroleum, chemical, pharmaceutical, food, mining, gas, highway threading, etc.

PSP钢塑复合管是一种新型金属与塑料复合的管材，采用钢带辊压成型为钢管并进行氩弧对接焊，内外均有塑层，中间为增强焊接钢管的多层复合结构，克服了钢管存在的易锈蚀、有污染、笨重、使用寿命短和塑料管存在的强度低、膨胀量大、易变形的缺陷，而又具有钢管和塑料管的共同优点，如隔氧性好、有较高的刚性和较高的强度，埋地容易探测等。

        PSP钢塑复合管运用先进成熟的“在线成型工艺”，塑造钢管和塑料管的形成过程同步内应力小。PSP钢塑复合管具有子弧焊工艺成型，焊接接缝，没有任何突起的塑料复合管，没有应力开裂点。独特的生产工艺，可以可靠和快速连接;改善表面腐蚀，美观大方;外管壁厚，设计合理;内衬塑料管，以确保通过直径为合理的壁厚;节约能源和保护环境，发展潜力突出。

PSP钢塑复合管适用于公共建筑，小区供水管道，可广泛应用于建筑给水工程，石油，化工，制药，食品，矿山，燃气，高速公路穿线等领域。
