3Cr Corrosion Resistant Tubing and Casing

In general, 3Cr series corrosion resistant tubing and casing employs special sealing screwed connector. It is applicable in oil and gas wells containing acid medium (like CO2 and Cl).

1. 3Cr corrosion resistant tubing and casing is with good CO2 corrosion resistance.
2. JST 3Cr anti-corrosion tubing and casing is manufactured under the unified quality assurance and quality control standard. During every production link from raw material to finished product, advanced untrasonic, swirl, flux leakage and other nondestructive testing equipment and methods are adopted to control and ensure high quality standard.
3. All our equipment technology is based on contemporary steel smelting, cold and hot processing, hydraulic sensing, electronic control, computer, information communication and other advanced technology.
4. 3Cr corrosion resistant tubing and casing is made of pure billet steel, which features stable ingredient, exquisite surface finish quality, high geometric dimensional precision, excellent mechanical property and technological performance.

CO2 corrosion is closely related with material Cr content and CO2 partial pressure and temperature in oil and gas wells. Cr is the most effective element to prevent CO2 corrosion because it can rapidly form a dense and thin Cr203 passivation film on the metal surface. As the Cr content increases, the CO2 corrosion resistance effect of this anti-corrosion steel pipe is enhanced. CO2 partial pressure is the main factor to affect the corrosion rate. CO2 corrosion rate accelerates with the increase of CO2 partial pressure. In general, as the temperature rises, the corrosion rate of materials also increases. The chemical composition of JST 3Cr corrosion resistant tubing and casing meets the following table:

Package 1. 3Cr corrosion resistant tubing and casing should be packaged into bundles for transportation.
2. Tubing is packaged by plastic steel packaging frame or packaging frame with similar materials.
3. Transportation container is specially designed so that 3Cr anti-corrosion tubing and casing have no direct contact with transportation container.
4. The tube bundles are fastened tightly in the container to prevent the collision between tube bundle and container or bundle.
5. The metal binding tapes will be separated from 3Cr corrosion resistant tubing and casing by rubber cushion or something similar.

PaymentEstablished in 1984, Jiangyin Changjiang Steel Tube Making Factory has been engaged in manufacturing seamless steel pipes for about 30 years. We mainly supply structure pipe, fluid pipe, high pressure boiler pipe, API pipe, marine pipe, alloy pipe, tubing, casing, line pipe, etc. Our products are extensively used in metallurgy, port, ship-breaking, manufacturing, real estate, chemical engineering, transportation and other industries. Our 3Cr corrosion resistant tubing and casing (3Cr anti-corrosion tubing and casing) are well appreciated for their advanced design, sophisticated manufacturing, excellent quality and full service.
