We can produce the lower-temperature Steel Pipe according to the ASTM A333 and ASME SA333 standards, and the and the production diameter from 8" to 48" in OD and wall thickness from 9.53 mm up to 140mm. We have been sold the GR.6 steel pipe about 20000 tons to date and the property of -45℃ impact value is about 100J, better than the standard`s requirements.
Yangzhou Chengde has the full capability to do every test in-house, from mechanical testing, chemical analysis, PMI, UT/Hydrotest etc. Chengde`s lab is qualified to ISO 17025 and CNAS standard, being proven the repeatability of accurate testings.
Each alloy pipe is subject to PMI before dispatch. The INNOV-X system performs non-destructive chemical analysis via simultaneous detection and quantification of fluorescent x-rays of multiple elements in test sample.
