Medium, temperature, soil condition and regulation decide the pipe. We match coating, insulation and jointing to each field's real duties — from potable water to mining gas drainage.
Potable-water hygiene licence certified coating for drinking mains; cement-mortar lined pipe for large transmission; TPEP for buried distribution networks.
Corrosive media and buried duty demand reliable internal lining and external coating; reuse and reclaimed-water lines in DN1600 class delivered.
PU pre-insulated pipe for buried heating networks; steel-casing steam pipe up to 350℃ for trunk steam lines — delivered to the Tibetan plateau and northern county heating upgrades.
3PE external coating to GB/T 9711 for buried gas mains; long-running supply to county gas-pipeline projects since 2015.
Inner-outer red coated pipe for sprinkler and standpipe systems; grooved joints for fast installation; galvanized pipe for small bores.
MA mining-safety certified dual-resistant (anti-static, flame-retardant) coated pipe for underground gas drainage and mine water supply/drainage.
Hot-dip coated conduit pipe for cable protection in power projects; socket joints for fast laying.
3PE / FBE / epoxy-tar systems for oil transmission and plant piping; heavy-duty coating for corrosive soils; Ningdong base drainage supply.
From medium to joint, one working day for a matched proposal.
