Here pictured is a job of 4 units of vent stake used for a compressor station
in petroleum transmission pipeline，each size at Out diameter of 1.1m，Height of
30m， and weights at 14tons.
The client has designed it to compliant with ASME SEC.Ⅷ DIV.1-2015, and a special metal material –SA516 Gr65(HIC) is used, it has a very low content of P and S, in order to give the vent stack enough corrosion resistance to hydrogen induced cracking (HIC), and good performance of anti-impact and anti fatigue.
We undertook the job for a Singapore customer and satisfied them with quality control and delivery deadline. They are very satisfied with our custom metal fabrication service.
