Specification 5C3 of the American Petroleum Institute standardizes 14 casing sizes from 4.5 inches (11.43 cm) to 20 inches (50.80 cm) outside diameter ('OD'). Up to 2 7/8″ OD (42″ mandrel) d-3/32″ 3 1/2″ to 8 5/8″ (6″ mandrel) d-1/8″ 9 5/8″ to 13 3/8″ (12″ mandrel) d-5/32″ Straightness: 4 1/2″+ 0.2% end-to-end (PE),.125″ in 5′ at each end: Length: Range 1 casing: 16-25′ Range 2 casing: 25-34′ Range 3 casing: 34-48′ Range 1 tubing: 20-24′ Range 2 tubing: 28-32.
L80 belongs to steel grades group of corrosion-resistant casing. L80 API oilfield casing pipe includes L80-1, L80-9Cr, and L80-13Cr. L80-1 is used in the H2S environment, while L80-9Cr and L80-13Cr are used in the CO2 environment. In the corrosive environment in which carbon dioxide predominates, Super 13Cr has a higher corrosion resistance than L80-13Cr.
With relatively high price, the product applies to more complicated geological conditions, and runs down deeper into the well. In the exploitation of oil and gas, the use of L80 is less frequent than J55, N80 and other materials.
Specifications
Inspection
Physical properties are checked and each length hydrostatically tested, normally to only 3,000 psi in the plain end (unthreaded) condition. The following are also checked:
- Dimensions
- Weights
- Straightness
- Lengths
Part of this inspection is to drift all lengths.
Despite all the American Petroleum Institute (API) specifications and testing, some tubing defects are still found after delivery; thus, some operators do further inspection.
Inspection Method
- Size and surface inspection
- NDT and pressure test and third party certication
- Hydrostatic
- Drifting test
- Physical and chemicail analysis
- Hardness and pressure test.
- Electromagnetic
- Magnetic particle
- Ultrasonic
