Standards and Technical Conditions for Supply:API Spec 5CT – Specification 5CT/ISO 11960, Specification for Casing and Tubing, Eighth Edition, Petroleum and natural gas industries-Steel pipes for use as casing or tubing for wells
Tubing are used as pipe to transport crude oil or natural gas from layer of the oil to surface, can hear better pressure during oil or gas production, and have smaller diameters.
Description
Tubing is a relatively small-diameter pipe that is run into a well to serve as a conduit for the passage of oil and gas to the field surface facilities for processing. Tubing must be adequately strong to resist loads and deformations associated with production and workovers. Further, tubing must be sized to support the expected rates of production of oil and gas.

Description
Slotted pipe are used for oil and gas wells. Steel casing pipes and tubing are applied to furnishing and installing cased tunnels, where they indicate to pass other utilities or obstructions without open excavation. Steel casing pipes and tube have smooth wall and a minimum yield strength of 35,000 psi. Corrosion-proofing water-based paint is applied on the outside pipe surface to protect against atmospheric corrosion during transportation and storage.

Description
Drill pipe: is hollow, thin-walled, steel or aluminium alloy piping that is used on drilling rigs. It is hollow to allow drilling fluid to be pumped down the hole through the bit and back up the annulus. It comes in a variety of sizes, strengths, and wall thicknesses, but is typically 27 to 32 feet in length (Range 2). Longer lengths, up to 45 feet, exist (Range 3).
Drill pipe wear belt with its certain wear resistance, protect the drill pipe and casing from strong wear. The main products in the market are ARNCO 100XT, 200XT, 300XT and 400XT.
Heavy weight drill pipe (HWDP) is usually run in between the drill collars and the drill pipe in order to prevent fatigue of the drill pipe in the vertical drilling industry. Heavy weight drill pipe is also utilized in the horizontal directional drilling (HDD) industry for added strength in high stress situations. Heavy weight drill pipe (HWDP) may be used to make the transition between the drill collars and drill pipe. The function of the HWDP is to provide a flexible transition between the drill collars and the drill pipe.
