Industrial Materials & Components from China’s Top Mills
Hicool supplies raw materials and finished components for shipbuilding, ship repair, offshore construction, and industrial projects. Every item ships with material test certificates (EN 10204 3.1 or 3.2) and dimensional inspection reports. We source from mills and foundries in Jiangsu, Zhejiang, and Shandong — China’s core industrial manufacturing region.
Piping Materials ASTM A106/A333 ASTM B467 (CuNi)
Seamless and welded carbon steel pipe (A106 Gr.B), low-temperature carbon steel (A333 Gr.6), stainless steel (TP304/316L), duplex (S31803/S32205), and CuNi 90/10 piping for seawater systems. Sizes from 1/2" to 24" NPS, schedules 10S to XXS. All piping supplied with mill certificates and hydrostatic test reports.
Flanges & Fittings ASME B16.5 ASME B16.47 EN 1092-1
Weld-neck, slip-on, blind, socket-weld, and threaded flanges in carbon steel, stainless steel, and CuNi alloys. ANSI Class 150 to 2500, DIN PN10 to PN100. Pipe fittings: elbows, tees, reducers, and caps in butt-weld and socket-weld configurations. Every flange shipped with marking, material certificate, and dimensional check report.
Gaskets & Sealing ASME B16.20 ASME B16.21
Spiral wound gaskets (304/graphite, 316L/PTFE), ring-joint gaskets (R/RX/BX), and non-metallic sheet gaskets for ASME and DIN flange connections. Material and pressure-class matched to your flange specification.
Fasteners & Hardware ASTM A193/A194 DIN 931/934
Stud bolts (B7/2H, B8/8M), hex bolts, nuts, and washers in carbon steel, alloy steel, and stainless steel. Hot-dip galvanized and PTFE-coated options for offshore and marine environments. Supplied with batch certificates and hardness test reports.
Material Quality Assurance Process
We take material traceability seriously. Every shipment is traceable from raw material heat number to your receiving dock.
Specification Verification
Cross-check your material specification against ASTM/ASME/DIN standards. Confirm grade, size, schedule, end preparation, and test requirements before sourcing.
Mill Selection
Source from pre-qualified mills with valid certifications (ASME, PED, AD2000). Priority given to mills with stock for urgent orders.
Inspection & Testing
Dimensional inspection, visual check, and documentation review. Third-party inspection (BV, SGS, TÜV) arranged on request. PMI testing for alloy grades.
Documentation & Packing
EN 10204 3.1 material certificates, inspection reports, packing lists. Heat number stamped on each piece. Export-grade packing with moisture protection.
