This paper indicates the requirements of non-destructive testing for pressure vessels in-service,researches the propagation characteristics of the acoustic emission(AE)wave that transmits in different
The floor of large atmosphere storage tank is detected by magnetic flux leakage testing instrument.The evaluation method of the function of instrument is lacked.The process of different thickness of f
Vibration in reciprocating compressors and piping systems occurs commonly,especially the one caused by pulsating gas flow,which may bring about failure problems.Based on the acoustic transmission char
The lattice dome,instead of the ribbed structure,has been popularized used in large crude oil tanks.The deformation and stress distribution of lattice dome under local differential settlement is studi
Reciprocating compressor auxiliary vibration usually caused by gas pressure pulsation.This paper studied the dynamic characteristics of gas pressure pulsation in constant-section long straight pipe of
Plastic pipe reinforced by cross helically wound steel wires(PSP)is a new plastic-matrix steel composite pipe developed in China recently.To understand the stress of PSP under internal pressure,a fini
Plastic pipe reinforced by cross helically wound steel wires(PSP)is a new plastic-matrix steel composite pipe developed in China recently.To understand the stress of PSP under internal pressure,a fini
Experiments detected the phenomena of electromagnetic emission induced by the failure process of concrete.In this paper,coupled stress-electricity.model had been established and the interaction proces
To study sealing properties of a reactor flange connection in the S-Zorb unit,the thermal-structural coupling analysis was carried out using ANSYS software.The sealing properties of the flange connect
The model of derrick crane was build and anlyzied by the software ANSYS,and the stress distribution of derrick crane under the typical conditions were calculated in this paper.The results showed that,
