Our drill pipe are manufactured in according to or exceeds the
requirement of API 5DP. The features are introduced as below:
1. The residual elements such as sulphur and phosphorus are
strictly controlled in the pipe body and tool joints material
during the steel making process, which makes the kind of material
with high physical properties.
2. Heat Treatment is a decisive process in the production of tool
joints and pipe body. Heat treatment must be uniform and deep
enough to ensure required physical properties full length,
especially in the critical sections of the connection and weld
zone. Heat treatment programs are established on the basis of the
actual chemical analysis of each heat of steel to ensure the
materials meet or surpass the requirements of API Specification.
3. The drill pipe undergo a full-length inspection that checks the
defects; especially the strict inspections on weldneck/upset region
are preformed with our both manual and automatic inspection
equipments to ensure the high quality.
4 The thread is the most important factor for drill pipes. All
threads would be machined with CNC Lathes and inspected with
related thread gauges in conformance with API Specification. All
threads would be phosphated or copperized and the roots are cold
rolled to improve the resistance of galling during initial break-in
and drilling operation. Upon the customer’s request, The Break-in
process is conduced to economize the rig handling time. All
Connections would be equipped with pressed steel or plastics steel
5. Besides SYBH's logo, API monogram, serial number of the finished
drill pipe and tool joints and size of the connections are painted
or stamped according to the requirements of API Standard
SYBH provides a full range of inertial friction welding drill pipes
in nominal sizes from 2-3/8” to 6-5/8” OD and various steel grades
(E-75, X-95, G-105, S-135), which are manufactured in according to
API 5DP Latest Edition and meeting the customer’s specified
