Usage: Oil and Gas Well Casing
Our API 5CT casing pipes are designed and manufactured in full compliance with international oil and gas standards. They are widely used to line the boreholes of oil and gas wells to support the well walls, prevent collapse and protect formation zones. Manufactured from high-quality carbon or alloy steel, these casing pipes are available in various grades, such as J55, K55, N80, L80 and P110, to suit different well conditions and depths.
With precision-controlled wall thickness, excellent mechanical properties and a range of end finishes (plain end, threaded or coupling), our casing pipes deliver high performance in both standard and high-pressure applications. Surface treatments include black paint, anti-corrosion coating and customisation upon request.
We offer comprehensive customisation, third-party inspection and fast delivery to meet the needs of drilling contractors and oilfield service providers worldwide.
