API 5L Pipe Specification (Updated on 2020) Octal Steel

API 5L steel line pipe adopts different steel grades, generally are Gr. B, X42, X46, X52, X56, X60, X65, X70, X80. Some manufacturers are capable of manufacturing steel grade up to X100 and X120. As the steel line pipe grades higher, more strictly control on the carbon equivalent control, and higher mechanical strength performances.Inconel Alloy 625 for Submarine PipelineThe Inconel alloy 625 clad steel pipe is used in submarine pipeline for transportation of natural gas or petroleum exploited. The Inconel 625 alloy provide corrosion resistance while the API 5L X65 or X70 backing steel pipe provide mechanical strength. It is manufactured by CRA weld overlay as per API 5LD.Application of welded pipe in submarine pipeline China The outer diameter of the welded pipe used in the South China Sea Liwan 3 1 deepwater submarine pipeline is 762 mm, the steel grade is X65 / X70 Mo, and the wall thickness is up to 31.8 mm, so as to increase the transportation capacity.

Carbon Steel Pipe Specificatoin Octal Steel

Typical carbon steel pipe material grades in API 5L Grade B, X42 to X70, ASTM A106 B, ASTM A53 B, ASTM A252 Grade 3 and ASTM A333 Grade 6 etc. Octal offers various of carbon steel pipes including seamless, welded (ERW EFW, LSAW, SSAW) steel pipes for the mining industries.Transmission electron microscopy of martensite/austenite The fine structure of martensite/austenite (M/A) islands in pipeline steel X70 was investigated using transmission electron microscopy. It was shown that the microstructure of the steel undergoing Effect of Reheating and Deformation Processes on DWTT The 30.9mm heavy gauge pipeline steel plate was industrial produced and the X70 UOE welded pipe with dimension in 1219×30.9mm was manufactured. The DWTT 85%FATT (fracture appearance transition temperature) of pipe body is as low as 20°C.

TOBO GROUP sales head offce in Shanghai. We are one of the Professional manufacturers Exporter Pipeline products in China .Our company was established in 1998, the plant covers 550, 000 square meters and a construction area of 6,8,000square meters, existing 260 workers and 45 technicians.Response of submarine pipelines to impacts from dropped Material properties and geometries of the submarine steel pipe are in the common ranges for the oil and gas offshore pipelines. A linear isotropic strain hardening model has been considered in the plasticity model of the steel material. This proves to be more suitable for quasi static monotonic loadings.Influence of Coastal Soil Environment on Local Corrosion The direct cause for the explosion accident occurred by Dong Huang pipeline is that the corrosion of pipeline was enhanced by coastal soil, which in turn resulted in thinning and then cracking of the pipe. Because localized corrosion cracking in coastal soils is a serious threat to the integrity and security for the pipeline, the effect of the coastal soil environment on localized corrosion
