Take on the role of the primary responsible person! ---------------------------------------------- The past decade has seen significant development in China’s chemical industry, with the emergence of many new processes, products, and equipment. China’s chemical processing equipment has also experienced substantial progress, which has contributed to the rapid growth of the petrochemical sector. Here, we have compiled a list of the achievements and breakthroughs made by Chinese equipment manufacturers in terms of larger-scale production and localization of equipment. Everyone is welcome to share, discuss, and exchange ideas; let’s cheer for Made in China and support the development of chemical processing equipment! ------------------------------------------------------ On December 16, 2016, a giant \"mushroom cloud\" rose at the China Petroleum Pipeline Breakage Control Test Site, located over 100 kilometers southeast of Hami City in Xinjiang. This marks the first successful full-scale natural gas blasting test of X90 steel pipes in our country, further enhancing our country’s research capabilities in fracture control for high-grade, large-diameter, high-pressure pipes.
As the demand for natural gas continues to rise, the use of large-diameter, high-grade steel pipelines capable of withstanding high pressures has become the standard in global natural gas transportation technology. This has led to increased attention being paid to the safety issues associated with natural gas transportation, and full-scale gas explosion testing is currently the most advanced method for obtaining data on pipeline performance. For a long time, full-scale gas blasting tests in our country have had to be commissioned to other organizations; this approach is costly and time-consuming, and it is not possible to obtain certain key experimental data. In 2012, CNPC designated the pipeline fracture control test site as a key field test project under major scientific and technological initiatives. In October 2015, China’s first pipeline fracture control test site was established in Hami, Xinjiang, where full-scale blasting testing technology for steel pipes was developed, filling a gap in domestic capabilities. On November 16 of the same year, the test site became an important part of the **Key Laboratory of Service Behavior and Structural Safety of Petroleum Pipeline Materials and Equipment** under the Ministry of Science and Technology. Over the past year or so, this testing facility has completed full-scale explosion tests on OD1422 X80 straight-seam pipes at 12 MPa and OD1422 X80 spiral pipes at 13.3 MPa for natural gas use, providing strong technical support for the construction of the China-Russia East Gas Pipeline.
Compared with the previous two blasting tests, the steel pipe used in this test was of a higher grade, namely X90； The pipe wall thickness is thinner, at only 16.3 millimeters (21.4 millimeters in the previous two cases), and the crack resistance of straight-seam pipes and spiral pipes was verified. Concurrently with this full-scale blasting experiment, the degree of damage and impact caused by the blasting of one pipeline on another pipeline laid in the same trench was also studied. The results provided a basis for testing and support for the design standards for laying natural gas pipelines in the same trench. The studies on the harmful effects such as blast waves, seismic waves, and thermal radiation resulting from gas pipeline explosions conducted during the same period in the pipeline fracture control test facility will also provide important technical support for the construction and safe operation of large-capacity, high-pressure, high-strength gas pipelines in China.
Haven’t seen it before, right? It looks really stunning
