Shandong with the Swiss mining technology limited production of W steel strip is made of rigid PVC and high density polyethylene as raw material, through extrusion molding for the strip, and then through the winding unit are wound into a tube, high-strength alloy plate cold pressed, and all kinds of bolt joint is formed using a common supporting union.

   W steel has the general plastic pipe all good corrosion resistance, small flow resistance characteristics, at the same time using a special A type rib structure, and adopts W shaped steel reinforced. It also has excellent rigidity and good strength and toughness, light weight, strong impact resistance, easy to damage characteristics.

   W strip bending section mould increased 54 times, W steel strip in the cold press process of hardening effect can improve the tensile strength of 28-46%, W steel strip connecting mode can adopt multiple styles, reliable connection can be made to achieve zero leakage of pipeline.

   Prestressing hollow anchor the effective realization of pressure grouting, not only can improve the overall stability of the surrounding rock, give full play to the stability of surrounding rock, also can effectively prevent moisture inside rock, prevent water damage and weathering, maintain the mechanical properties of rock.

   W steel reinforced pipe wall smooth little conveying resistance, anti fouling ability, steel reinforced pipe manufacturing, using the latest and shaping process, smooth inner wall than steel, equivalent absolute roughness is 0.08mm, and the inner surface of steel pipe equivalent absolute roughness 0.20mm under the same conditions, the flow is more than 30% higher than steel, resistance scaling ability is more than 20% higher than steel, is especially suitable for hard water quality in the region of the conveying water medium.
