A slotted pipe is a metal pipe with precisely cut longitudinal or spiral slits, commonly used in oil fields, water wells, and other applications requiring controlled fluid flow. These pipes are manufactured by cutting multiple staggered or straight slits of specified dimensions into oil casing pipes or tubing using ultra-thin cutting sheets or beam cutting technology. The slit width typically ranges from 0.2mm to 0.5mm, with cross-sectional shapes including rectangular, trapezoidal (with angles of 3-8 degrees), or custom-designed perforations (e.g., round holes). This design ensures permeability rates of 0.5% to 10%, and the slit pattern can be customized according to user requirements.

Advantages of Slotted Pipe
One of the key benefits of slotted pipes is their excellent corrosion resistance. During the manufacturing process, special anti-corrosion materials are incorporated to ensure durability, preventing chemical reactions even after prolonged exposure to air. Additionally, these pipes are highly durable and can withstand harsh environments without compromising performance.
Key Features of Slotted Pipes
- Effective Sand Control
Suitable for wells with sand particle sizes greater than 0.3mm, preventing blockages while allowing fluid flow.
- Precision Cutting
The slits have smooth, burr-free edges with excellent verticality, ensuring uniformity.
- High Flow Capacity
A 27/8” slotted pipe with 300 slits per 1.5 meters provides 2.4 times the flow area compared to oil pipes of the same specification.
- Enhanced Corrosion Resistance
Overall anti-corrosion treatment improves resistance to wear and extends the pipe's underground service life.
- High Strength & Durability
Manufactured using J55 or N80 petroleum casing, offering superior strength and resistance to deformation.
- Optimized Inner Diameter
The large inner diameter facilitates easy configuration of pipe strings, enhancing operational efficiency.
Slotted pipes offer a reliable solution for industries requiring high-strength, corrosion-resistant pipes with optimized fluid flow capabilities. Their customizable design and durability make them an essential choice for oil extraction, water filtration, and other specialized applications.
