This Order contains some large diameter and heavy 904L seamless pipes and A182 904L slip-on flanges according to B16.5 CLASS 150. Flanges were finished within 15days, and most pipes were finished within 30days because we have sufficient ready stock 904L round bars in ready stock. But our factory had a accident when produced the large and heavy 904L seamless pipes with 323.8 outside diameter and 12.7 mm wall thickness. The mother pieps pierced from round bars are with cracks, so they are rejected and we have to prpare new round bar to make mother pipes, it makes us 20days' delay of delivering the pipes, And makes our valued customer get their shipment date on LC revised. We feel sorry for the delay, sometimes delay happens due to some unpredictable reasons. Then the frequent update report from factory is very important for customers.

Pipe Marking

Thanks to our workers overtime working during the National Day Holiday, we finished the larege pipe 323.8*12.7 and catched the latest vessel. Production is a complex thing, especially for the not regular size and materials. When delay comes, the first thing we have to do is to let customer now the situation, and to help us to confront the situation together, I think most of the time customer will stand with us if we show our sincerity to solve problem.
