J55 P110 Q125 V150 Oil Casing Carbon Steel Tube / Galvanized Carbon Steel Pipe

High quality oil and gas round square pipeline seamless carbon steel pipe

Description:

Carbon steel pipe can be divided into seamless steel pipe, straight steel pipe, spiral steel pipe, high frequency welded steel pipe and so on.Carbon steel seamless steel pipe is a kind of long steel.
The pipe has a hollow section and is used in a large number of pipelines for fluid transportation, such as those for oil, natural gas, gas, water and some solid materials.
Generally, the outer diameter of hot-rolled seamless pipe is greater than 32mm, the wall thickness is 2.5-75mm, the outer diameter of cold-rolled seamless pipe can be up to 6mm, the wall thickness can be up to 0.25mm, and the outer diameter of thin-walled pipe can be up to 5mm, the wall thickness is less than 0.25mm, and the precision of cold rolling is higher than that of hot rolling.
General carbon steel pipe: it is made of 16Mn, 5MnV and other low-alloy structural steels, such as 10, 20, 30, 35, 45, 45 etc.Seamless pipes made of mild steel such as 10 and 20 are mainly used for fluid transportation pipes.The seamless pipe made of medium carbon steel such as 45 and 40Cr is used to make mechanical parts, such as mechanical parts of cars and tractors.Carbon steel tubes are generally used for strength and flattening tests.The hot-rolled steel pipe is delivered in the hot-rolled or heat-treated condition;Cold rolling is delivered as heat treatment.

Specification:

Technical standards:
API 5CT: specification for casing and tubing
API Spec 5B: specification for machining, measuring, and inspection of casing, tubing, and pipe threads
API TP 5C3: formulas and calculations for casing, tubing, and pipes used as casing or tubing, and technical reports for casing and tubing performance tables
ISO 13678: petroleum and natural gas - evaluation and testing of threaded grease for casing, tubing, and pipe lines
Brand:ASTM steel tube can be divided into different steel grades according to the strength of steel casing, namely J55, K55, N80, L80, C90, T95, P110, Q125, V150, etc.
Different grades are adopted for different well conditions and depths.
The casing itself is also required to have corrosion resistance under corrosive conditions.
API seamless steel pipe also requires the casing to have impact resistance in the place of complex geological conditions.
Tubing specification:
OD WT 1.900 "~4.500" 0.125 "~0.630"
Casing specification:
OD WT 4.500 "~16.00" 0.205 "~0.660"
