LSAW Steel Pipe para projetos de infraestrutura
setembro 28, 2022n80-tubo de revestimento
Outubro 13, 2022N80 oil casing and N80 tubulação de aço sem costura are important equipment for oil drilling, e seu equipamento principal também inclui tubo de perfuração, tubo de núcleo e revestimento, colar de perfuração e tubo de aço de perfuração de pequeno diâmetro.
There are three lengths specified in the API standard for N80 oil casing and N80 seamless steel pipe: R-1 is 4.88~7.62m, R-2 is 7.62~10.36m, and R-3 is 10.36m to longer.
API 5CT N80 Casing:
N80 Casing is placed downhole to provide structural integrity to the wellbore and must withstand external-collapse pressure from rock formations and internal-yield pressure from fluid and gas. Também deve manter sua própria inércia e resistir à pressão de torque e transaxial colocada nele durante a execução do downhole.
API 5CT N80 Tubing:
N80 Tubing is placed within the casing. Ele é usado para o transporte de petróleo e gás da rocha fonte para a cabeça de poço.
N80 oil casing and N80 seamless steel pipe are mainly used for oil well drilling for the support of the well wall during drilling and after completion to ensure the normal operation of the drilling process and the entire oil well after completion
The types and packaging of N80 oil casing and N80 seamless steel pipe are divided into two types: short threaded casing and its coupling and long threaded casing and its coupling according to SY/T6194-96 “óleo invólucro”. According to SY/T6194-96, domestic casing should be bundled with steel wire or steel belt. Each sleeve and the exposed part of the clamp thread should be screwed with a protective ring to protect the thread.
N80 oil casing and N80 seamless steel pipe according to SY/T6194-96. The casing and its couplings are of the same steel grade. The sulfur content < 0.045%, and the phosphorus content < 0.045%.
N80 oil casing and N80 seamless steel pipe are taken according to the provisions of GB222-84 for chemical analysis. Chemical analysis is carried out in accordance with the provisions of the relevant part of GB223.
N80 oil casing and N80 seamless steel pipe American Petroleum Institute ARISPEC5CT1988 1st edition regulations. Chemical analysis according to the latest version of ASTME59 preparation, according to the latest version of ASTME350 chemical analysis.
