A+ supplier credit rating on the Sinopec EPEC procurement platform

Jiangxi Wanlong Industrial Co., Ltd. has been rated A+ in the legal-entity credit evaluation of the Sinopec EPEC procurement platform. The certificate number is 20240102063. It is valid for three years from July 2024.
What the rating is
EPEC is the Sinopec procurement platform. Its legal-entity credit evaluation rates a supplier's credit standing as a company. It is a credit rating, not a product approval: it does not replace the licences and test records that apply to each piece of equipment.
The certificate can be checked on the EPEC platform by its number.
Why it matters to buyers
Before inviting a fabricator to quote, procurement teams on energy and petrochemical projects usually check two things: whether the company is sound, and whether it is licensed for the equipment. The A+ rating speaks to the first question. Our licences answer the second.

- Pressure vessels: special equipment production licence TS2236612-2027, fixed pressure vessels, Class D (medium and low pressure), valid from 2023-08-28 to 2027-08-27.
- Pressure piping: special equipment production licence TS3836019-2027 for GC2 industrial piping installation, valid from 2023-04-15 to 2027-04-14.

The plant behind the rating
Wanlong was established in 2003 in Jinxian, Nanchang, Jiangxi. The site covers 133,000 m², with a 30,000 m² vessel workshop and an annual capacity of 50,000 t. Of 180 staff, 45 are engineers and technicians.
From this one site we fabricate pressure vessels, storage tanks, SF double-wall underground fuel tanks, steel structures and skid-mounted units. Plate is cut on CNC laser, flame and plasma machines, rolled on 3- and 4-roll benders up to 70 mm, and welded by SAW and GMAW to qualified WPS/PQR. Welds are inspected by RT, UT, MT and PT, with radiography in our own RT room.
Our energy and petrochemical references include SF double-wall tanks supplied under framework agreements to a national fuel retailer, and tank installation for a top chemical group's ethylene complex in Yantai.
