ISO 9001, ISO 14001 and ISO 45001 certificates renewed to 2028

Jiangxi Wanlong Industrial Co., Ltd. has renewed its three management system certificates. ISO 9001 for quality management, ISO 14001 for environmental management and ISO 45001 for occupational health and safety are now valid from 18 June 2025 to 17 June 2028.

Registration numbers

• ISO 9001 (quality management): 01725Q10433R2M
• ISO 14001 (environmental management): 01725E20277R2M
• ISO 45001 (occupational health and safety): 01725S10249R2M

All three certificates run from 2025-06-18 to 2028-06-17.

What the certificates cover

The ISO 9001 scope lists the work buyers most often send us:

• Fabrication of steel structures and space frames
• Manufacture of Class D (medium- and low-pressure) fixed pressure vessels
• Production of SF double-wall underground fuel tanks
• Production of skid-mounted units
• Installation of GC2 industrial piping
• Construction work under our Grade 2 qualifications for building construction, building decoration and mechanical and electrical work

The ISO 14001 and ISO 45001 scopes cover the same activities and add petrochemical engineering construction and foundation work, both at Grade 2.

How to use the scope when you evaluate us

A certificate number on its own does not show whether the system applies to your order. Check that the product on your purchase order appears in the scope. Then check that it is also covered by the matching licence:

• Pressure vessels: special equipment production licence TS2236612-2027, fixed pressure vessels, Class D, valid to 2027-08-27. The licence notes that vessel design is outsourced.
• GC2 industrial piping: licence TS3836019-2027, valid to 2027-04-14.
• Construction: qualification D236A02207 for petrochemical engineering, building construction and mechanical and electrical general contracting, Grade 2, valid to 2030-02-14.

What stays the same on your order

The renewal does not change how equipment is built. Plate is checked against mill test reports before cutting. Welding follows qualified WPS/PQR. Welds are inspected by RT, UT, MT and PT, with radiography in our own RT room. Pressure vessels are hydrostatically tested at 1.25 × design pressure with a 30-minute hold. Each shipment leaves with its data book.

The certificates apply to our single site at No. 2666 Jinxian Avenue, Jinxian Economic Development Zone, Nanchang, Jiangxi. The site covers 133,000 m², with a 30,000 m² vessel workshop, an annual capacity of 50,000 t and 180 staff, 45 of them engineers and technicians.

Copies of the three certificates can be sent with any quotation.
