Perforated Casing Pipe Used in Oil Well for Oil Easy Flowing

图片
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 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&

Straight Welded Perforated Tube for High Pressure Applications

图片
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.

Spiral Welded Perforated Pipe with Various Perforation Patterns

图片
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

Spiral Lockseam Perforated Pipe Used in Fluid Filtration Fields

图片
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. Click  here  for more information. 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".
