Slotted pipe works as a separator to filtrate the sand in oil or gas well, the main function is to control sand. Different grade and type (slotted, perforated, wire-wrapped and so on) of pipes will be applied for different stratum during oil and gas exploration.
Performance: API SPEC 5CT standard.
Slotted width: (0.1-4)mm±0.03mm;
No. of slots: No limit;
Slot scheme: Parallel, interlaced, spiral;
Distance between slots on surface: No limit.
Diameter of perforation: (12~12.7)mm±0.1mm;
Perforation scheme: Parallel, interlaced;
Feature of product:
Slotted pipe is processed using casing pipe which has high yield strength and difficult to be deformed. Rectangularity of pipe end is good, cutting surface is smooth and has no burrs, slots and perforations are distributed uniformly. Area of flux is relatively much higher than the flux area of casing with same dimension, which is good for fluid flowing. It has higher performance while applied in horizontal well and deviated well. Anti-corrosion coating is also can be applied to slotted pipe to form a compact protection layer, which enhances the anti-corrosion performance and abrasive resistance, service life can be extended effectively. Slotted pipe can be applied for the sand control situation of which the diameter of sand is larger than 0.3mm. Operation and application is easy and convenient, inner drift diameter is large which is easy for serial pipe connection.
