1. Other glass steel pipes
1.1. FRP pipes for oil fieldsBecause FRP pipes have excellent corrosion resistance and high pressure resistance, they have been widely used in the petroleum industry. Compared with other anti-corrosion measures, they have significant technical and economic benefits.
The application of FRP in oil fields mainly includes 5 aspects: 1) production tubing of shallower wells; 2) oilfield surface pipelines containing corrosive media: oilfield surface pipelines include oil and gas pipelines, gathering and transportation pipelines, pipelines that require water quality, Brine pipelines, sewage reinjection pipelines, pipelines in sewage treatment stations, buried pipelines with severe external corrosion, pipelines for corrosive media in refineries, etc .; 3) injection pipes for enhanced recovery; 4) FRP casings; 5 ) Pipes for offshore platforms. The pressure level of high-pressure glass steel pipe can reach 34.5MPa.
