Perforated /Slotted Casing and Tubing
The screen pipe is installed at the bottom of seamless or welded steel pipes in oil well, water wells, geothermal wells, brine wells, etc for the separation of liquid and gravel in formation. Due to the differences in formation structure, gravel granularity, and liquid viscosity, the screen tube required also varies in the hole and slot size and shape.
In recent years, the demand for this product increasingly grows with the rapid development of oil and mining industry, the maturing of oil well drilling technology in desert regions, the rise of large-scale offshore oil production, as well as the booming development of geothermal wells, brine wells, and deep wells.
The traditional well drilling, casing laying and blasting perforation technology cannot adapt to the complex terrain and meet the needs of high efficiency and high return modern drilling and production. Our screen pipe has been widely applied to underground liquid exploitation in the mining industry. It overcomes the difficulty in cutting hole and slot and meets the high precision requirements of hole and slot size and shape.
The product is widely used in oil exploration for effective sand prevention in old wells, newly drilled oil wells, exploration(test) wells, offshore oil exploration wells, horizontal wells, sidetrack wells, etc. It can also be found in geothermal wells, brine wells, and daily water wells. The general vertical shaft adopts circular slotted or perforated screen pipe instead of blasting perforated type which may lead to many troubles. Our product is preferred by customers both at home and abroad.
Our company is a specialized screen pipe manufacturer and supplier in China. We offer an extensive line of products, including API casing, API tubing, PUP joint, API coupling and more.

Slotted Pipe
The slotted pipe uses a variety of methods to cut many longitudinal or spiral slots of certain specifications in the line or staggered pattern. This product is made using special thin blade cutting and laser cutting. The cross section of slot is available in rectangle, trapezoid(trapezoid angle of 3-8°)， and other special shapes. It can guarantee a permeability of 0.5％-10％. The slot can be processed according to user requirements.
- This screen pipe is mostly processed based on the body of J55 or N80 oil casing, which has high strength, and is not easy to deform.
- The product enjoys good verticality of slot edge, smooth cut edge with no burrs, and uniform slot.
- The 2 7/8” slotted pipe has 300 slots per 1.5m. It achieves an open area of 72㎡ which is 2.4 times larger than the tubing of the same specification. This is beneficial to fluid flow.
- It has more distinct superiority in deviated and horizontal wells.
- Due to the entire antiseptic treatment, a dense protective layer is formed on the surface. This improves the corrosion and abrasion resistance, and effectively extends the service life of the slotted pipe for underground work.
- It is suitable for sand retention in the well with the sand particle size greater than 0.3mm.
- The product is easy to use and large in inner diameter, which also facilitates the configuration of pipe string.
- Material: Carbon steel, stainless steel.
- Pipe type: Oil casing, tubing.

Perforated Pipe
- The perforated pipe uses J55 or N80 oil casing as the processing body. This ensures high strength and no distortion.
- The hole is uniform, smooth and has no burr.
- The overall anticorrosive processing results in a dense protective layer on the surface of screen pipe, so as to improve its corrosion and wear resistance, and effectively prolong the downhole working life.
- The perforated pipe comes with simple use. Due to big inside diameter, it also brings convenience for pipe string configuration.
- The type of hole can be freely selected by the customer.
