The pipes are with thin wall, plywood cases packing could prevent damage

EN 10216-5 is a Eruopean standard for stainless steel seamless pipe, it is similar to American standard ASTM A312, but with more strict tolerance on sizes and testings, and the chemical composition requirements is a little bit different with A312, generally our products could meet the requirements of both standards at the same time.

These pipes are ordered according to dual standards, EN 10216-5 and ASTM A312, material 1.4539 according to En 10216-5 is with P below 0.030%, Cu 1.2%-2%, N below 0.15%, and A312 requires P below 0.040%, Cu 1%-2%, N 0.1% and below, others are the same, our material could meet both standards.

The pipes are 8" OD, and Sch10S wall thickness, it is thin to 8" inch pipes, the pipes are produced by cold rolling processes, finished pipes are with very even thickness and good surface. We could produce even more large pipes with cold rolling machines, up to 20 inch, your are welcomed to send inquiries with large diameter and thick wall pipe and tubes, and you will be catered with good quality and very good prices.
