Outer Diameter (OD): 219mm – 3048mm (8" to 120")
Wall Thickness (WT): 5.0mm – 25.4mm
Length: 6m – 12m (Customized lengths up to 35m available)
End Finish: Beveled ends (30°/35°) for on-site welding or plain ends.
External: 3PE (Three-Layer Polyethylene), FBE (Fusion Bonded Epoxy), or Coal Tar Epoxy.
Internal: Liquid Epoxy (conforming to AWWA C210 for potable water) or Cement Mortar Lining.
Surface Standard: Compliant with DIN 30670, CAN/CSA Z245, and ISO 21809.
100% Hydrostatic Test: Every pipe is tested under pressure to ensure zero leakage.
Real-time X-Ray & UT: Online ultrasonic testing and final X-ray inspection of weld seams to identify any internal defects.
Dimensional Precision: Strict control over out-of-roundness and pipe-end diameter to ensure seamless field welding.
Third-Party Inspection: We welcome SGS, BV, Lloyd's, and ABS for on-site witness and 3.2 Certificate issuance.
Nesting (Pipe-in-Pipe): We can nest smaller diameter pipes (e.g., 600mm) inside larger ones (e.g., 1200mm). This maximizes shipping space and can save you up to 35% on freight.
End Protection: Heavy-duty steel or plastic caps prevent bevel damage during transit.
Professional Loading: We provide detailed lashing and loading plans for both Bulk Carriers and Container shipping.
