Company news, technical notes and industry observation — three sections, updated from the same plant that makes the pipe.
Diameter range, wall-thickness capability, weld seam length and economics — the four dimensions that decide a long-distance pipeline.
Epoxy + adhesive + polyethylene: three layers with three jobs. Field joint closure and holiday detection decide the service life.
County-level heating networks across northern China are being renewed. Work is squeezed into the non-heating season, which raises the bar on staged delivery and changeover without shutting down the heat.
Heat number, chemistry, mechanical properties, hydrostatic test, NDT — check these five and acceptance gets a lot safer.
High-salt, highly corrosive service demands more from coating adhesion and impermeability — the epoxy plus polyethylene structure delivers both.
Local standards, routine third-party inspection, and delivery time weighing more: competition in export orders is shifting from price to compliance and delivery.
Based in Puwa Industrial Park, Yanshan Economic Development Zone, Hebei; founded 2012, more than 110 employees, four product families: spiral, anti-corrosion, plastic-coated and pre-insulated pipe.
The site sits at about 4,500 m altitude; insulation thickness was set by the plateau heat-loss target, with end sealing and joint closures supplied together.
Belt and Road / CPEC water line for the Saindak mine: over 38,000 m of line, manufacturing supervised throughout, and a company representative stationed in Pakistan for 40 days until the line was closed.
Tell us the medium, diameter and design pressure — our engineers will answer with a specification, not a brochure.
