The paper provide the site welding technology on the hot wall hydrogenation reactor vessel made of 2.25Cr-1Mo-0.25V steel for Xinjiang Dushangzi Petrochemical Company 60×104 t/a hydrocracking installation. Meanwhile, it mention the main quality control points in every working processes, such as the site assembly, welding, non-destructive testing, post weld heat treatment and hydraulic pressure test.
It is suggested that specified NDT quality management model should be established according to GB/T19000 family standards to put NDT system control into practice effectively.
Analyzed and compared are the NDT items between the three commonly-used steel linepipe standards namely,API Spec. 5L-2000,GB/T9711.1-1997and GB/T9711.2-1999(SAW parts)in a bid to guide production,inspection and purchase of steel tubular products.
If the transverse modulus is determined by non-destructive testing with vibration tests, including a mathematical identification procedure, no significant influence of the fibre treatment can be observed.
In X-ray diffractometry, a method from non-destructive testing, we want to recover the stress tensor of a specimen with the help of X-ray measurements.
Korolev, the oldest worker of the Central Research Institute for Heavy Machinery (TsNIITMASh), has told about some episodes on the initial stages of the ultrasonic NDT development.
Taking medium density fiberboards (MDF) as samples, the feasibility of the applications of wavelet analysis in a nondestructive test is discussed in this paper.
The effects of grain angle, thickness of face veneer, and shelling ratio on dynamic modulus of elasticity (E) of veneer-overlaid particleboard composite (VOP) were examined by using nondestructive test.
