Production Notes of SSAW Steel Pipe

Date: 2023-04-03

Production Notes of SSAW Steel Pipe SSAW steel pipe in the production process, we need to pay attention to a series of matters. Except for the following test items, according to the API standard and other relevant standards and the special requirements of some users, but also the need for steel, steel pipe and other tests Destructive tests, including physical and chemical properties of the raw materials into the plant sampling, visual inspection of 100% steel . A. Oiled marking: steel after passing were oiled to prevent corrosion, and according to user requirements for marking. B. Leveling Milling: The flat steel anvil machine so that the original curl, and then through the edge milling machine for two-sided steel milling, so as to meet the requirements of the plate width, plate edge parallelism and groove shape. C. Shear molding: the steel plate production line along the outer edge of the spiral curl into a tube. D. Butt cut: double-sided submerged arc welding using advanced technology to pre-welding, internal welding, outside welding. The welded steel pipe using a plasma-foot cut to specification length.

How to Manage Oil Casing in Corrosive Well Environments

Oil casing in corrosive well environments must meet both mechanical design requirements and the demands of the service environment,Carbon dioxide (CO₂),hydrogen sulfide (H₂S),chlorides,water chemistry and temperature can influence corrosion behavior and material suitability,Choosing a casing grade based on strength alone may leave important risks unaddressed,
How to Choose the Right Oil Casing for Well Conditions

Choosing the right oil casing requires more than matching a nominal diameter or selecting a higher-strength steel grade,Casing must meet the well design,expected mechanical loads,connection requirements and service environment,For drilling contractors,EPC procurement teams and international buyers,confirming these requirements before ordering helps reduce specification errors,delivery delays and costly changes during project execution,
How to Identify Early Signs of Oil Casing Failure

Oil casing provides structural support and helps maintain well integrity throughout drilling and production,When casing or related well barriers deteriorate,the consequences may include leakage,operational interruptions and increased safety risks,However,casing damage is not always visible at the surface,and early warning signs do not necessarily confirm a failure,
How Is Oil Casing Quality Verified Before Delivery

Oil casing quality must be verified against the requirements agreed for the order,including steel grade,dimensions,connections,inspection scope and documentation,Before shipment,buyers need to know not only whether the product has been inspected,but also whether the required tests are complete,the results meet the specified acceptance criteria,and the records correspond to the supplied materials,
How to Reduce Casing Damage During Cementing Operations

Casing damage during cementing can complicate well construction,delay subsequent operations and raise concerns about well integrity,Although cementing helps support the casing string and isolate formations,the operation involves mechanical loads,fluid pressure and coordination between drilling and cementing teams,
