High-tech enterprise (2023) with 16 patents; potable-water hygiene licence and MA mining safety mark; full in-house testing from chemistry to hydrostatics.
Government recognitions and product certificates actually held — scan copies available with our quotation.
Purchased with the SAW lines and coating lines — not outsourced, so results come with the pipe, not weeks later.
Weld-seam radiography on spiral and straight-seam pipes.
Pressure test up to 1000-tonne class holding per standard.
Heat-by-heat chemical analysis of incoming coil and weld metal.
Surface and near-surface defect detection.
Hardness checks on base metal and coating systems.
Toughness verification for low-temperature duties.
Tensile and bend tests on base metal and welds.
Magnetic thickness gauge, paint-film impact tester, spark leak detector, alcohol-lamp combustion box, motorized pressure pump.
Mill certificates checked; spectrometer chemistry on every heat.
Forming, welding and coating parameters logged per shift.
X-ray on welds, spark testing on coatings, dimensional gauging.
Hydrostatic test, hardness, impact and final visual before packing.
Heat-number traceable certificates dispatched with each shipment; site support on call.
Diameter, wall thickness, length and ovality checked pipe by pipe against the order contract. Results are recorded and traceable back to the coil heat number.
For key projects our engineers stay on site: arrival acceptance with the owner and supervisor, welding and joint-coating guidance, and after-sales follow-up until the line is commissioned.
