What is Carbon Equivalent Formula? Carbon Equivalent (CE) is an important parameter in steel production as it indicates the weldability, hardenability and susceptibility of a steel to brittle fracture. Carbon Equivalent is particularly important in welding applications because the composition of a steel greatly affects its behavior during and after welding. How to calculate carbon equivalent? CE = C + Mn/6 + (Cr+Mo+V)/5 + (Ni+Cu)/15 *Calculate carbon equivalents online: https://www.knauf-interfer.com/en/service/online-tools/cev-calculator For example API 5L PSL2 X70M LSAW steel pipes with…

How thick is API 5L Grade B Schedule 80? API 5L Grade B Schedule 80 pipe thickness varies by nominal pipe size (NPS). Schedule 80 refers to the wall thickness of the pipe, which is typically thicker than Schedule 40 or Schedule 20 pipe. However, in order to determine the exact thickness of an API 5L Grade B Schedule 80 pipe for a given NPS, it is necessary to refer to a standard specification. The American Petroleum Institute (API) provides…

How to cut the AS1163 steel pipes?
