When international buyers evaluate a pipe fittings and flanges manufacturer, certifications are usually the first checkpoint. For procurement teams in oil & gas, petrochemical, power, marine and offshore projects, a supplier must demonstrate not only production capacity, but also traceability, quality management discipline, and compliance with internationally recognized standards.
Hebei Jinhang Pipeline Equipment Manufacturing Co., Ltd. operates as a manufacturer of steel pipe fittings, flanges, forged components, and related pipeline products, with quality system registrations and third-party attestations that support export-oriented project supply.
Quality Management and HSE/Energy System Certifications
Hebei Jinhang holds a range of system certificates covering quality, environmental, occupational health and safety, HSE, and energy management. These include:
*API Spec Q1, 10th Edition – Registration No. Q1-5323
Scope: Manufacture of Steel Pipe Fittings and Connectors for the Oil and Gas Industry.
Effective: April 2, 2025; Expiration: April 2, 2028.
Note: The certificate confirms API Q1 quality management system registration; Design is excluded under this registration.
*ISO 9001 Quality Management System
*ISO 14001 Environmental Management System
*ISO 45001 Occupational Health and Safety Management System
*HSE Management System Certificate
*Energy Management System Certificate conforming with GB/T 23331-2020 / ISO 50001:2018 and RB/T 119-2015
These system certificates help support consistent production control, document management, internal audit discipline, corrective action tracking, and continuous improvement across the manufacturing scope.
PED / CE Compliance Attestation
The company also holds an EU Attestation of Compliance / AB Uygunluk Onayı related to 2014/68/EU Pressure Equipment Directive requirements.
From the submitted compliance document, the attestation covers pressure-related accessories such as pipe fittings/pressure accessories for carbon, stainless and alloy steel, with reference to QA system requirements for materials under Annex I, para 4.3, and Category II pressure accessories.
This type of documentation is often requested for European projects or international EPC contracts that reference PED/CE compliance as part of their quality and pressure-equipment documentation package.
ASME Authorization
Hebei Jinhang holds an ASME Certificate of Authorization. Based on the provided certificate, the authorized scope is:
*Manufacture and assembly of power boilers at the above location only
*Authorized: December 02, 2024
*Expires: December 02, 2027
*Certificate Number: 62030
Pipe fittings, flanges and forgings are manufactured to applicable ASTM/ASME material and dimensional standards, but the ASME authorization scope shown is specific to power boilers, not a general statement covering all fittings or pressure-vessel stamps unless separately confirmed by additional ASME certificates.
BV Mode II Scheme Recognition
The company holds Bureau Veritas Marine & Offshore Recognition for BV Mode II Scheme, Certificate No. SMS.W.II/149674/A.0, expiring 24 Dec 2028.
The recognition summary covers:
*Flange – G0230
*Forging – G0247
*Pipe / Tube and Fittings – 0479
Product scope includes items such as pipe flanges, forgings, and pipe fittings in carbon, C-Mn, alloy, austenitic stainless, ferritic-austenitic stainless and low-temperature service materials, within the stated sizes, pressure classes and thickness ranges defined in the schedule.
This BV recognition supports supply into marine, offshore and classified-project environments where BUREAU VERITAS approval or acceptance is required.
DNV Approval of Manufacturer
Hebei Jinhang also holds DNV Approval of Manufacturer Certificates for:
*Steel Pipes and Fittings – Certificate No. AMMM00003D1
*Steel Forgings – Certificate No. AMMM00003CY
Both certificates were issued from Hamburg on 2025-12-09 and are valid until 2028-12-08. They are based on DNV rules/class programmes such as DNV-CP-0252 Steel pipes and steel pipe fittings and DNV-CP-0247 Steel forgings, with application to ships and marine/offshore-related structures and equipment.
The approvals cover piping fittings and forgings in carbon/C-Mn, alloy, austenitic stainless, Cr/Ni/Mo, duplex and ferritic-austenitic materials, with manufacturing methods including hot-formed/seamless-based piping fittings and open-die/closed-die forgings, subject to the grade, size, weight and heat-treatment conditions listed in the schedules.
Material Standards and Grade Coverage
The company’s product and material documentation references a wide range of ASTM/ASME and EN standards, including:
*ASTM A105, A106, A234, A213, A240, A312, A320/A320M, A333, A335, A350, A351/A351M, A387, A403, A420, A515, A516, A671, A672, A691
*ASME SB-165, SB-166, SB-167, SB-168, SB-423, SB-424, SB-425
*BS EN 10216-2
*Duplex and stainless-related UNS grades such as UNS S31803, UNS S32750, and nickel-alloy/austenitic grades as listed in approval schedules.
This material coverage supports [carbon steel elbows], [butt weld pipe fittings], [flanges], [pipe fittings] and related items for oil & gas, water, steam, structural, low-temperature and corrosive-service applications, subject to project specification.
How to Verify a Supplier’s Certifications
Before placing an order, procurement teams should check:
*Certificate validity – issue and expiry dates, with no gaps in coverage.
*Registration or license number – cross-check via the issuing body’s official database or verification link where available.
*Scope of approval – confirm it covers the product type, size range, material grade, and service condition.
*Exclusions – for example, API Q1 registration here excludes Design.
*Traceability documents – mill test reports, material certificates, heat numbers, and inspection records.
*Third-party inspection – ability to accommodate SGS, TÜV, BV, DNV or client-appointed inspectors at agreed witness points.
Frequently Asked Questions
Q1: Do you have API certification?
Yes. Hebei Jinhang holds API Spec Q1, 10th Edition registration, No. Q1-5323, for the manufacture of steel pipe fittings and connectors for the oil and gas industry. This is a quality management system registration; it is not an API Monogram license unless separately confirmed.

We hold an EU Attestation of Compliance related to PED 2014/68/EU, covering relevant pressure accessories in carbon, stainless and alloy steel. Specific project scope should be confirmed against the current certificate and client requirements.
Q3: Can you provide material traceability certificates?
Yes. Mill test reports / material certificates with grade and heat-number traceability can be provided per order, subject to product type and project documentation requirements.
Q4: Which third-party inspections can you support?
We can accommodate independent inspection and testing witness points, including dimensional checks, NDT, hydrostatic testing, PMI and documentation review, as specified by the buyer or EPC.
Q5: What is the ASME scope?
The ASME Certificate of Authorization shown covers manufacture and assembly of power boilers at the registered location. Fittings and flanges are produced to applicable ASTM/ASME standards, but ASME stamp scope should be confirmed from the current certificate.
