C110 Seamless Pipe Material Grade API Spec 5CT
Forwell Energy Equip stocks a variety of sizes in tubular form for this grade category even higher such as 13CR etc.
The following terms and definitions are used in this part.
3.1 Wellhead blowout preventer, BOP
In drilling operation, a pressure-bearing mechanical device used to control the fluid and drilling fluid pressure of oil and gas wells. 3.2 Braze
A welding method that fills the gap between materials to be welded with low melting point nonferrous metals by capillary effect.) 3.3 Carbon steel
Carbon content is less than 2wt%, manganese content is less than 1.65wt% and other elements, but excluding those iron-carbon alloys that intentionally add a certain amount of elements (usually silicon and/or aluminum) as deoxidizers.
Note: The carbon content of carbon steel used in the petroleum industry is usually less than 0.8%. (3.4 Christmas tree
Equipment for controlling fluid production or injection at the wellhead. 3.5 Cold work
The process of plastic deformation of metal at a certain temperature and strain rate to produce strain hardening. It is usually (not necessary) completed at normal temperature.
3.6 Corrosion-resistant alloy, CRA
It is an alloy used to resist uniform and local corrosion in oilfield environment. In this oilfield environment, carbon steel will be corroded. 3.7 Ferrite ferrite
A body-centered cubic crystal in iron-based alloys. 3.8 Ferrite steel
At room temperature, the microstructure of steel is mainly ferrite.
