Nondestructive testing of large diameter and thick wall anticorrosive spiral steel pipe
In the process of spiral steel pipe production, the function of nondestructive testing is mainly two points. First, it provides continuous and real-time process quality control for raw materials, semi-finished products and wind, and the two is the defects of small welded pipe to be qualitative, quantitative and accurate, thus providing guidance for the common disposal; and three is based on the undirected acceptance standard. Quality classification of spiral welded pipe.
Nondestructive testing technology enables us to produce and use spiral welded pipe products in a safe and economical way. In the field of NDT, there are dozens of NDT methods that have been applied effectively. The commonly used NDT methods in the field of spiral welded pipe manufacture are RT, UT, MT, FP and so on.
