Supply metal collars for drilling shafts will API certificate.


Standard Drill Collar Features &

Options

API pin stress relief groove and box boreback

An API pin stress relief can be used on all drill collars and downhole tools. It

is a recommended option in situations where fatigue can occur as a result of

bending. By removing any unengaged threads in the high stress areas of the

drill collar connection, it is less likely to crack due to fatigue because the bending will take place in the area of the connection with smooth surfaces that are free of stress concentrations.

Internal bore treatment

This option generates a compression level of at least 60, 000 PSI at a given

depth. This provides the collar with an excellent resistance to stress corrosion

cracking.

The company is the first to get the ISO9001-2000 quality management system certificate and has also attained the certification of CCS, GL and KR.The products have been exported to korea, Japan and Euramerican countries and also sold to domestic large-scale enterprises, which have a good reputation among the customers.
