Dedicated to EPC contractors, industrial plants, and energy projects across Vietnam, Philippines, Indonesia, and Malaysia. From rigorous mill vetting and 100% dimensional testing to on-site live video surveillance, we eliminate cross-border sourcing risks.
Pipes are the structural spine of your industry. Beyond basic brokering, ADK deeply audits Chinese mill capacity to make overseas procurement feel like local supervision.
Eliminating shell brokers and phantom capacities. We perform on-site factory audits, license checks, and rolling line assessments to guarantee Tier-1 origin.
Preventing negative tolerance cheating and fake test certs. We conduct digital caliper OD/WT checks, positive material identification (PMI), and MTC validation.
No need to station staff in China. ADK provides rolling, coating, beveling, bundling, and container loading multimedia records directly to your engineering team.
Engineered milestone management. We lock raw material rolling dates, manage buffer stock, and synchronize port logistics to prevent EPC project penalties.
Compliant with ASTM, API 5L, ASME B16.9, EN, and DIN standards for high-pressure fluid handling, petrochemicals, structural columns, and corrosive environments.

Our resident quality engineers perform structured checks at every stage, providing cloud-accessible MTCs, PMI readings, and high-resolution visual logs.
Verification of Chinese steel billet heat numbers, chemical composition spectroscopy, and mechanical yield strength checks before pipe forming.
Continuous ultrasonic (UT) weld seam testing, hydrostatic pressure holding (100% tested), and digital wall thickness gauge logging.
Verification of 30°-35° pipe end bevels, black paint / 3LPE coating thickness gauge tests, plastic end caps, and heat-stamped markings.
Moisture barrier desiccant placement, heavy seaworthy steel strap bundling, timber blocking in containers, and dispatch to loading ports (Tianjin/Shanghai).
We facilitate SGS, BV, TÜV, or Lloyd's Register inspections at Chinese mills prior to final bill of lading dispatch.
Deep technical understanding of distinct pressure, temperature, and corrosion demands across Southeast Asian industrial capital projects.
High-pressure transmission, refinery processing units, and storage tank farm connections requiring API 5L PSL2, A106, and ASTM A335 alloy steel.
Superheater, reheater, and heat exchanger tubing operating under elevated thermal and steam stresses with strict grain size compliance.
High-chloride, acid-resistant piping loops employing austenitic stainless steel 316L and Duplex 2205 for continuous municipal & industrial flow.
Heavy hollow sections, foundation piling tubes, and HVAC fluid distribution networks requiring accurate straightness and certified welding.
Transparent execution logs, mill test validation, and zero-defect records across energy and manufacturing projects.
Supplied 180 MT of ASTM A312 316L seamless pipes with custom ASME B16.5 flanges. 100% PMI verified on-site prior to port dispatch.
Coordinated rolling and ultrasonic testing of ASTM A335 P22 alloy pipes. Solved negative wall thickness risks through continuous resident auditing.
Integrated package of 450 MT ERW & LSAW pipes with 3LPE external anti-corrosion coating and matching weld fittings.
Clear, transparent answers on mill sourcing, payment terms, and quality control.
We maintain full physical inspection presence. Our resident engineers visit the fabrication site, verify Chinese business licenses, evaluate rolling line tonnage and hydrostatic test logs, and check heat batch certificates directly against billet suppliers.
Yes, 100%. We routinely coordinate witness points for SGS, Bureau Veritas, TÜV, DNV, and client representatives at Chinese mills. Dispatch only occurs once the official inspection certificate is signed and approved.
Our standard technical response SLA is 2 hours to acknowledge and clarify project parameters, followed by a detailed technical quotation within 24 hours including steel grades, mill origin options, pricing, and shipping schedule to ASEAN ports.
All carbon steel pipes receive anti-corrosive black vanish or light oiling. Pipe ends are fitted with plastic bevel protectors. Small-to-medium pipes are bundled with heavy steel strapping and nylon slings for break-bulk or container loading with desiccants.
Whether you are an EPC procurement director with active Bill of Quantities (BOQ) or an industrial manufacturer seeking steady long-term supply, our China engineering desk will review and return your full pricing breakdown within 24 hours.
Rapid review of wall schedules, steel grades, standards, and port terms (FOB/CIF).
Includes verified mill certificates, delivery schedule, and tolerance guarantees.
Support for live video streaming of mill tests and digital MTC document verification.
A dedicated project manager will be assigned to your case immediately.
