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

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 o

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.

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.

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.

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.

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.

Perforated filter disc, made of stainless steel, aluminum, low carbon steel, copper, brass, has different shapes such as triangle, round. With high accurate filter precision and high anti-corrosion performance and rust resistance.
