Continuous Casting The continuous casting process adopts rectangular billets with a production specification of 350 mm × 470 mm. During production, it is ensured that the tundish preheating time exceeds 2 hours and the tundish temperature is maintained above 1150°C. Proper drying and moisture-...Read more -
Introduction to the Classification of Sleeve Stabilizers
1.Mechanical sleeve stabilizer Mechanical sleeve centralizer is one of the most common sleeve centralizers, which mainly consists of a bracket and two movable fixtures. The fixture can be adjusted according to the size of the wellbore and can accommodate sleeve of different diameters. It usual...Read more -
oil drilling tooling
In oil drilling, the drilling tool is driven to break the rock, drill underground, drill out of the wellbore at a specified depth, and supply the oil or gas producer to obtain oil or natural gas. A commonly used oil drilling rig is mainly composed of eight parts, including power machine, conve...Read more -
The Role of the Hardfacing of the Non-Magnetic Stabilizer
Petroleum non-magnetic stabilizer is an accessory used for oil field extraction, mainly used to reduce friction between drill pipe and hole wall, prevent drill pipe bending, and ensure that the drill bit drills at the designed angle and trajectory. Non-magnetic stabilizers are usually made of ...Read more -
Structural features of drill bit
1. Floating bearing structure is adopted, and the floating element is made of new materials with high strength, high elasticity, high temperature resistance and high wear resistance, and the surface is treated with solid lubricant. While reducing the relative linear velocity of the bearing pai...Read more -
