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 thread protectors.
KINGWELL 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
1,Drill Pipe Body
KINGWELL drill pipe performs a strict
quality control on manufacturing and inspection process from the initial
material selection to final inspection to meet the requirement of the customer.
The drill pipe is manufactured with top-quality alloy steel, which SYBH will
perform the strict mechanical and chemical re-inspection. The advanced
inspection system can precisely detect the defects and check the dimensional
tolerance to ensure API required 87.5 minimum percent wall thickness, and even
provide 95 percent minimum wall thickness in every pipe.
KINGWELL tool joints are made of AISI
4137H premium alloy steel fully Q&T with IPSEN furnace imported from Japan.
All tool joints should be inspected by fluorescence magnetic particle and
The threads and Bevel shoulders
are machined by CNC Lathe and gauged to API specification, which provides
interchangeability between various types of connections. All threads are
phosphatized or coppered to reduce the possibility of connection
