Basic knowledge and uses of seamless steel pipes, oil casings and pipes

Knowledge of oil casing Basic knowledge Oil casing is a large-diameter pipe that acts to fix the wall or bore of oil and gas oil wells. The casing is inserted into the wellbore and fixed with cement to prevent the wellbore from separating the rock formation and the wellbore from collapse, and to ensure the circulating flow of drilling mud to facilitate drilling and exploitation. Different types of casings are used in oil production: Surface oil casingprotects the well from contamination by shallow water and shallow gas layers, – supports wellhead equipment and maintains the weight of other […]

Seamless Steel Pipe Wall Thickness Variation Control Technology

Reducing the amount of variation, or achieving more wall thickness consistency, can be the difference between meeting a customer’s requirements or not. It also helps to reduce or even may eliminate the customer’s need for subsequent processes such as machining. Seamless tube typically is manufactured on a two-roll piercer mill. In some cases this step alone is sufficient to produce tube that satisfies the customer’s requirements. ومع ذلك, if wall thickness consistency needs further improvement after piercing, يمكن لمنتج الأنبوب استخدام معدات إضافية وخطوات معالجة. نوعان من المعدات هما مطحنة استطالة متقاطعة (المعروف عنه […]
