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. PCP-2:  Perforation Patterns. PCP-3:  Stainless steel perforated casing pipes.

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.

Straight seam welded perforated pipe   is manufactured by perforated metal sheet which is cut to desired size and then rolled and welded into a tube. It is mainly used in high pressure applications where spiral tubes can't reach the working pressure. Straight seam welded tube  can be made of carbon mild steel, stainless steel and aluminum alloy. The tubes are fabricated with diverse  patterns of perforation , hole shape and end margins.  Product description: Material:  stainless steel 304, 316L; mild steel, aluminum alloy; Hole diameter:  3/8"; Wall thickness:  up to 0.06"; Outside diameter:  up to 10"; Length:  up to 10'; Hole shape:  round, square and slot. SWT-2:  Stainless steel straight welded perforated tube.

Perforated metal tubes are mainly manufactured by two methods - welded or lock seam of perforated metal sheet.  Straight lock seam perforated tubes   are designed for light duty applications like oil and lube filtration industries. Main materials are carbon steel, aluminum alloy and stainless steel. They are designed with diverse patterns including perforation patterns, hole shapes and end  margin forms . Product Description: Material:  stainless steel, aluminum and carbon mild steel; Hole size:  up to 1/2"; Thickness:  up to 0.05 inch; Hole shape:  round, slot and square; Length:  up to 10'; Outside diameter:  as required. SLP-2:  Straight lock seam perforated pipe with margin.

Spiral welded perforated pipe  is helically formed and automatically welded of continuous sheets of perforated metal based on high precision and high quality of welding. Compared with straight welded tube, spiral welded tubing is approximately 15% stronger. Spiral metal tube does great job in holding high pressure and high impacts. Spiral welded tubing has been processed by centerless grinding, plating, sand blasting, deburring and buffing. These finishes will make subsequent operations smooth and cost-efficient. Welded spiral perforated tube is available in various margin and  end patterns . See them in  technology section . SWP-1:  Spiral welded steel perforated pipes. SWP-1:  Spiral welded mild carbon steel perforated pipes. Product Descriptions: Materials:  Mild carbon steel, stainless steel. Thickness:  0.024" to 0.165". Hole diameter:  3/8". Open area:  up to 65%. Hole Shape:  round, slot and square. Holes Distribution:  straight line, staggered

Lock seam perforated pipe  is made by folding up the overlapping edges against each other, then folding them over in the same direction a number of times. It has flush surface outside and lock seam inside. This type perforated tubing is the popular option of fluid filtration like center tube in the filter house. Mild steel and stainless steel are common materials of manufacturing spiral perforated tubes. For generally applications, carbon steel is available to serve. However, for corrosive work conditions, stainless steel perforated pipe is a cost-efficient choice in the long terms. Note:  End forms,  margin patterns  and holes distribution are bespoke.

Product Description: Material:  mild carbon steel, stainless steel or as ordered; Hole diameter:  no less than 0.06"; Open area:  up to 65%; Thickness:  0.10" to 0.06"; Outside diameter:  1" to 8"; Length:  up to 60". SLT-1:  Stainless steel spiral lock s

Aluminum perforated tube  is extensively used as screens, filters, shields and guards of engineering, construction and material handling industries. It is especially suitable for low-temperature applications when its strength increases and ductility retains. However, when its working temperature reach 400 °F, aluminum tube tends to lose some strength. One advantage of using aluminum perforated pipe depends on its ideal corrosion resistance and strength-to-weight ratio. For some applications, weight should be kept in a low level to ensure smooth operation. Under this condition, aluminum tubing is the best choice. It not only provides enough strength but weight less than other metals like stainless steel or mild steel. Note: Available in various end margin forms and  perforation patterns . See  more . Fabrication options: Straight or spiral welded; Straight or spiral lock seam; Product description: Material:  aluminum alloy; Hole diameter:  3/8"; Thickness:  up to 0

Stainless steel perforated pipe  is great alternative for exhaust tubing of automotive applications. Owing to its excellent corrosive resistance and overall properties, stainless steel perforated tubing is completely recycled. Perforated stainless steel pipe are manufactured with  various shapes of holes  - round, slot and square in straight or staggered forms. You can choose  lock seam  or welded fabrication for your perforated pipe. Hole size can be customized according to your requirement. Stainless steel perforated tube is widely used in harsh environments where common carbon steel is easy to get rust or fail. SPT-1:  Stainless steel perforated tubing.

Perforated steel tube  (either hot rolled or cold rolled) is more cost-efficient compared with the other two types like stainless steel tube and aluminum tube. Though carbon steel is subjective to corrosion and rust, external protective coating will remedy its shortcomings. The frequent method to resolve corrosion problems is hot-dip galvanization, electro galvanization or other powder coated. These finish options greatly improve their service time and recyclability.
