Usage:

钢管无处不在，可以在地下和住宅墙壁，实验室以及商业和工业结构中找到。无缝的钢管运输液，包括水，天然气，废物和空气。存在三种生产钢管的制造方法。

seamless steel pipes are produced using an extrusion mold. Welded steel pipes are produced by rolling a sheet of steel into a tube and welding the seam. Seamless steel pipes are less expensive. The third method is casting. Molten steel is poured into a casting mold.

在以下条件下，我们的钢管和管是过程的首选：

• high temperatures
• aggressive media (e.g. acid and lye)
• 和/或高压

我们有一个经验丰富的专业人士团队，拥有多年的制造经验。
