Casing with Screen Jacket: High-Performance Wire-Wrapped Screen Pipe for Oil & Gas Filtration In the demanding world of oil and gas extraction, effective sand control and filtration are critical to maintaining well integrity and maximizing production efficiency. We are proud to introduce our premium Casing with Screen Jacket, a high-performance wire-wrapped screen pipe engineered specifically for crude oil filtration applications. Manufactured to meet API 5CT standards, this advanced downhole solution combines decades of metallurgical expertise with precision engineering to deliver reliable sand control in even the most challenging reservoir conditions. Product Specifications At the core of our offering is the 4-1/2″ OD, 11.6 PPF, K55 grade casing with BTC R3 thread connection, featuring a precision wire-wrapped screen jacket. The K55 steel casing body provides exceptional mechanical strength and collapse resistance, while the wire-wrapped screen layer is manufactured using tightly controlled winding technology to achieve consistent slot openings tailored to specific formation sand particle sizes. Parameter Specification Outer Diameter 4-1/2 inches (114.3 mm) Weight 11.6 PPF (pounds per foot) Material Grade K55 Carbon Steel per API 5CT Connection Type BTC (Buttress Thread Casing), R3 Screen Type Wire-Wrapped Screen Jacket Certification API 5CT Compliant Application Crude Oil Filtration & Sand Control Key Features & Advantages Our Casing with Screen Jacket delivers a comprehensive set of performance advantages that set it apart in the global oilfield equipment market: Superior Filtration Precision — The wire-wrapped screen jacket is manufactured with exacting slot size control, ensuring precise sand particle filtration and minimizing sand production that can damage downhole pumps and surface equipment. Exceptional Corrosion Resistance — K55 grade steel, combined with proprietary surface treatment processes, provides outstanding resistance to corrosive downhole fluids, significantly extending operational service life. Extended Service Life — The robust construction and high-quality materials translate to longer well completion intervals and reduced workover frequency, lowering the total cost of ownership for operators. High Mechanical Strength — The K55 casing body with 11.6 PPF wall thickness offers excellent collapse and burst ratings, making it suitable for medium to deep well applications where formation pressures demand reliable casing integrity.
