Oil Drill Pipe 4-1/2 API SPEC 5DP with Higher Tensile Performance Straightness
Oil drill pipe
We can supply all kinds of drill pipes that are consistent with API
SPEC 5DP or SY.
Drill pipes can be made as customers' requirements and be equipped
with the same type of tool joints.
Advanced drill pipe production lines can transfer the welding
parameters to the best position to ensure the quality of welding
zone; the heat treatment process with the feature of internal and
external cooling at the same time can make a more reliable and
stable mechanical character. Application of automatic weight,
length measurement and automatic spray records can ensure products'
traceability. Application of thickening and heating lines and 1250
tons of upsetting machine can ensure the thickening size meet the
standard of API SPEC 5DR Using of CN furnace for whole pipe body
heating and quenching, tempering machine's advanced heat treatment
process can ensure the pipe's mechanical character. Tube hydraulic
straightening machine ensures the straightness and coaxiality of
pipe body.
