Abstract

The invention provides an oil-gas pipeline restraint simulator and a testing method thereof. The oil-gas pipeline restraint simulator comprises a first fixing plate, a second fixing plate, a rigidity restraint support, a first sample pipe fitting, and a second sample fitting, wherein the first fixing plate and the second fixing plate are oppositely arranged, the rigidity restraint support, the first sample fitting and the second sample fitting are arranged between the first fixing plate and the second fixing plate. The testing method includes setting the rigidity restraint support, welding the sample pipe fittings, cutting the testing sections, and testing data. As shape and size of the sample pipe fittings can be tested according to the full size of the oil-gas pipeline in actual operation, size is free of limit, and through the simple pipe fitting welding structure, restraint simulation testing of the oil-gas pipeline can be realized. The oil-gas pipeline restraint simulator can simulate high restraint and restraint stress and is wider in application range and more accurate in testing.

Description

technical field

[0001] The invention relates to the field of oil and gas pipeline welding, in particular to an oil and gas pipeline restraint simulation device and a testing method thereof. Background technique

[0002] The degree of restraint indicates the degree of restraint of the weldment during welding, and is an important mechanical parameter for the quantitative study of welding cracks. With the rapid development of my country's oil and gas pipeline projects, the production of pipeline steel has been greatly increased. A large number of welding work is involved in oil and gas pipelines. The crack problem caused by excessive welding restraint in the welding process is becoming more and more serious. Therefore, In order to improve the problem of cracks in the welding process of oil and gas pipelines, it is particularly important to test the welding restraint degree of oil and gas pipelines during the construction period.
