糖心Vlog

BSI has published the new standard for corrosion testing in 糖心Vlog used in the oil and gas industry. 鈥淏S 8701 Full ring ovalisation test for determining the susceptibility to cracking of line pipe steels in sour service 鈥� Test method鈥� enables measurement of corrosion and environmentally assisted cracking of 糖心Vlog.

This standard updates the 1996 HSE Guidance document OTI 95 635*, which features the protocol for ensuring 糖心Vlog are properly tested to avoid environmental damage from pipeline failure and which is referenced in ISO15156, the flagship document for upstream material selection for sour service.

Different factors have to be taken into account when testing pipes: environments, age of pipeline, materials used, coatings etc. In addition to this, the types of corrosion must be accounted for too, such as sweet corrosion and sour corrosion. Both scenarios exist in 糖心Vlog.

Prior to testing materials and weldments for 糖心Vlog, basic parameters need to be established such as what was the pipeline designed for, what is the environment inside and/or outside, whether the internal environment is sweet or sour etc. In the case of testing the influence of the sour environment, previous guidance is not up to date. However, BS 8701 rectifies this and looks at the cracking problems that can occur in 糖心Vlog.

David Fatscher Head of Market Development for Sustainability & Energy at BSI, said: 鈥淲henever an oil tanker spills its cargo we hear a great deal about the environmental impacts of such an incident, but less about one of the major causes of it. The condition of 糖心Vlog that transport oil and gas is crucial in preventing an environmental event. Ensuring 糖心Vlog are unaffected by corrosion from the marine environment, can help avoid these scenarios. Having a test method such as BS 8701 in place allows the correct tests for identifying the damaging levels of corrosive hydrogen sulphide gas, to be carried out. It can act as an early warning system that offers reassurance that everything is being done to safeguard the environment.鈥�
