Our company has developed together with the relevant scientific research organizations series filter products for petroleum chemical filtration: Oil sand control screen (anti-sand filter blocks), spiral welded stainless steel filter tube (spiral welded pipe), straight seam welded stainless steel filter tubes, well received by the oil field customers.
Product Property and Characteristics:
1.Unique design of filter ring
Grade sand control filter and exterior protection cover are welded with the side ring to form a unit. The times of welding between the filter structure and the center tube are reduced to the minimum, hence greatly reduce the effect of the welding to the sand strength.
2.With side opening exterior protection cover (optional)
During transport, the protection cover can protect the grade sand control filter layer, protect the sand control filter layer from punctured or damaged during the procedure of entering the well . In the oil and gas wells production, using of it can effectively prevent the direct erosion and damage of the fluid to the grade sand control filter layer and it can extend the service life of Screen.
3.Center tube has unique spiral pattern
Center tube has high precision perforated tube with standard oil and glove tubes. The spiral perforating form of the center tube reduces the opening area of the tube cross section and maintains the strength of the center tube to the maximum. The sand is blocked outside of the perforated screen while the oil, gas or water goes through the perforated opening then enters into the screen.
4.Easy for installation, less work time.
Small external diameter, light weight, easy to move in the long-distance horizontal level
