Specification :

1.Type of thread:tubing NU/EU/IJ casing STC/BTC/LC
2.Grades:API J55;API K55;API N80;API L80; API P110
3.OD:Tubing1.05"~4 1/2"casing 4 1/2-13 3/8
4.WT:tubing 2.87~16.00mm casing 5.21-22.22
5 length:R1/R2/R3
6.Tubing is used to extracting petroleum and natural gas from a well
Casing serves as wall of a well

7. Pipe end :thread with one side coupling and protected by the plastic hat
8.Application:Oil Well Engineering,Oil Gas Engineering,Chemical Engineering,thermoelectric Enginering,Water Delivery Engineering,Ship Engineering.
9 Internal and external surface of the casing is not folded, hair pattern, separation, cracking, rolling, folding and scarring.These defects have been completely removed,clear the depth of no more than 12.5% of the nominal wall thickness.
10.Casing and threaded coupling surface should be smooth, does not allow burr, tear and impact strength sufficient to interrupt threads and other defects in tight junction
11.In order to assure product quality.our company has established inside QC lab with advanced chemical and physical inspection equipment.such as metallographic microscopes,and NDT testing equipment and so on.
