Perforated Casing Pipe Used in Oil Well for Oil Easy Flowing

Perforated casing pipe creates a channel between the pay zone and the wellbore to make easy flow of oil and gas to the wellbore. Manufactured by N80, J55 or 13Cr110 which are confirmed by API casing or tubing specification, our perforated liners are featured by high strength and anti-deformation. Punched holes with diameters from 3/8" to 1/2" are arranged in straight or staggered conditions. Upon requests, holes and their configurations can be customized to satisfy diverse applications.
To guarantee the smooth operation, internal and external burrs are deburred according to API standards.
Distribution Pattern of Perforations
Punched holes are distributed in straight line or staggered forms. For staggered holes, the percentage of open area is higher than straight. You can choose any type according to your specific conditions.
Three hole-distribution patterns of perforated casing pipes: non staggered, spiral staggered, and staggered.

Perforated Square Tube for Making Telescoping Tube, Sign Post

图片
Perforated square tubing  is cost effective choice of manufacturing square sign post and telescoping square tubing, which provide easy installation and savings in time and labor cost. One prominent advantage is its unique telescoping feature. Smaller sizes fit smoothly and snugly into the next larger size, which is possible by the help of high-frequency resistance welding. Road signs, warn signs and billboards are amounted to the tubing back-to-back. Square perforated tubes  are fabricated with a wide range of hole sizes and wall thicknesses for the application of mechanical and structural. Galvanized steel and aluminum alloy is the frequent used metal alloy. They can hold much more weight than wood or plastic tubes. In addition, owing to its special structure, it is easy to replace old broken tubing. Product descriptions: Material:  plate steel; Finish:  hot-dipped galvanized; Sheet metal gauge:  12 and 14; Width:  1-1/2"; Height:  1-1/2"; Length:  8' and 10&
