Characteristic of casing pipe

Date: 2019-10-14

Characteristic of casing pipe Casing is important to oil drilling equipment, and its main equipment includes drill, core pipe and casing, drill collars and drilling small diameter steel pipe and so on. The casing is used to support oil and gas wall of the pipe, to ensure that the drilling and completion of the process of the normal operation of the wells. Depending on the drilling each well depth and geological conditions, to use several layers of casing. Casing cementing go down after using it with tubing, drill pipe are different, can not be reused, a one-time consumable materials. Therefore, the total consumption of the casing is 70% of the oil well pipe. Casing can be divided according to usage: catheter, surface casing, casing and production casing. Casing is a large-diameter pipe, play a fixed oil and gas wells, or wellbore wall effect. The casing is inserted into the well hole, fixed with cement to prevent the formation and borehole spaced borehole collapse and to ensure circulation of the drilling mud to the drilling mined. Casing is mainly used for drilling oil wells during drilling and after completion of the support wall to ensure that the conduct of the drilling process and completion of the wells after the regular oil casing normal operation. OCTG mainly used for oil and gas well drilling and oil and gas transportation. It includes oil drilling pipe, oil casing, pump tubing. Oil drill pipes are mainly used to connect the drill collar and drill and pass drilling power. Casing is mainly used for drilling and completion of the right wall of the support, to ensure that the conduct and completion of the drilling process after the normal operation of the wells. Pumping wells at the bottom of the tubing will mainly oil, gas transported to the ground. Casing is to maintain the wells run lifeline. As different geological conditions, underground complex stress state, pulling, pressing, bending, torsional stress acting on the combined effect of the tube, which the casing itself, the quality of the higher requirements. Once the casing itself is damaged for some reason, could lead to the whole production wells, or even scrapped. Post time: Oct-14-2019

How to Choose Stainless Seamless Steel Pipe for High-Temperature Applications

High-temperature piping requires more than simply selecting a stainless steel grade,As temperature increases,material strength,corrosion behavior,thermal expansion,pressure resistance,and long-term stability become increasingly important,For this reason,stainless seamless steel pipe should be selected against the complete service condition rather than temperature alone,
How Stainless Seamless Steel Pipe Is Manufactured: From Billet to Finished Pipe

Stainless seamless steel pipe is used in chemical processing,oil and gas,power generation,water treatment,food processing,and other applications where material performance and pressure integrity matter,But a finished pipe does not become reliable simply because it is made from stainless steel,Its quality is built through material control,forming,heat treatment,dimensional control,inspection,and traceability,Understanding how stainless seamless steel pipe is manufactured gives engineers and technical buyers a better way to evaluate suppliers beyond price,surface appearance,or a product catalogue,
LSAW Steel Pipe Maintenance: Extend Pipeline Service Life

Installing a properly specified LSAW steel pipe does not eliminate the need for pipeline maintenance,Once a pipeline enters service,corrosion,coating deterioration,mechanical loading,ground movement,operating changes,and environmental exposure can gradually affect its condition,For large-diameter pipelines,a practical maintenance program should focus on identifying changes early and taking corrective action before a manageable condition develops into an integrity problem,The objective is not simply to inspect the pipe,It is to understand the condition of the complete pipeline system and respond based on evidence,
How LSAW Steel Pipe Performs in High-Pressure Pipeline Systems

High-pressure pipeline systems place demanding requirements on pipe material,dimensions,weld integrity,inspection,and operating conditions,For large-diameter pipelines,LSAW steel pipe can be an effective solution because its manufacturing process allows large outside diameters and substantial wall thicknesses to be produced from steel plate,However,selecting LSAW steel pipe for pressure service is not simply a matter of choosing a thicker wall,The pipe specification needs to match the actual design pressure,temperature,fluid,diameter,applicable code,and service environment,
How to Prevent LSAW Steel Pipe Corrosion in Water and Buried Pipeline Systems

LSAW steel pipe is widely used for large-diameter water transmission,buried pipelines,and other infrastructure projects where strength,dimensional control,and long-term service reliability are important,However,pipe strength alone does not prevent corrosion,For buried or water pipeline systems,corrosion protection should be considered from material selection and coating through transportation,field welding,installation,and long-term inspection,A coating system should also be selected according to the actual operating environment rather than simply by initial cost,
