Perforated Pipe

Stainless steel is also called corrosion-resistant steel or CRES when the alloy type and grade are not detailed, particularly in the aviation industry. Stainless steel does not readily corrode, rust or stain with water as ordinary steel does, but despite the name it is not fully stain-proof, most notably under low oxygen, high salinity, or poor circulation environments.

Stainless steels contain sufficient chromium to form a passive film of chromium oxide, which prevents further surface corrosion and blocks corrosion from spreading into the metal’s internal structure, and due to the similar size of the steel and oxide molecules they bond very strongly and remain attached to the surface.

Stainless steel perforated casing pipes are manufactured according to standard API 5CT and 5B, material includes: ASTM SS304/304L, SS316/316L, etc.

Perforated casing liner providing customized service for special order

Perforated liner with punched holes in staggered pattern

Perforated casing pipe

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.

Uses: used in filter of automobiles internal-combustion engine, sieving of mine, Medicine, grain, sound insulation of room, ventilate of grain depot, etc.
