Recently, HNHY Special Steel Pipe Technology Group received the A333 Gr6 low-temperature offshore engineering pipe certificate issued by the headquarters of the Bureau Veritas (BV), which means that HNHY is ahead of its Chinese counterparts in the professional field, and the international market space has been expanded again.
This certification lasted for two years and was the first extension of HNHY's single steel classification society in the state of full group spacing and full delivery.
As one of the 12 official members of the International Association of Classification Societies, Bureau Veritas is a world leading inspection and certification group.
This certification will help HNHY to further develop the deep-sea market of low-temperature pipeline pipe varieties, establish the advantage of leading domestic peers, and provide high-quality products for global offshore pipeline customers.
