PRODUCTS DETAILS

Casing and tubing widely used for oil and gas develop, Casing and tubing are essential components in the oil and gas industry used for the extraction and transportation of hydrocarbons (oil and natural gas) from underground reservoirs to the surface. They play crucial roles in ensuring the safety, integrity, and efficiency of drilling and production operations. Tubing is a kind of pipeline used to transfer the crude oil and natural gas from the oil layer or gas layer to the ground after the drilling is finished. Tubing can allows the pressure generated during the extraction process. Tubing produced as the same way as casing, but the process called "upsetting" is additionally needed to thicken the tubing pipe. Casing is used to protect the boreholes that have been dug into the ground for oil. Used same as the drill pipe, oil well casing pipes also allow the axial tension pressure, so high-quality high-strength steel is required. OCTG casings are large diameter pipes that are cemented into the borehole.The packaging method for steel pipes involves cleaning, grouping, wrapping, bundling, securing, labeling, palletizing (if necessary), containerization, stowing, sealing, transportation, and unpacking. Different kinds of steel pipes and fittings with different packing methods. This comprehensive process ensures that the steel pipes shipping and arrive at their destination in optimal condition, ready for their intended use.

♦ Nominal linear masses, threads and coupling (col. 2, 3, 4) are shown for information only. ♦ The densities of martensitic chromium steels (L80 types 9Cr and 13Cr) are different from carbon steels. The masses shown are therefore not accurate for martensitic chromium steels. A mass correction factor of 0,989 may be used. ♦ Non-upset tubing is available with regular couplings or special bevel couplings. External-upset tubing is available with regular, special-bevel, or special clearance couplings.
