Steel pipes and fittings from Turkey
Borşen Boru, Turkey, is a distributor of steel pipes, valves and fittings, and a
manufacturer of TIG welded stainless steel pipes. The company is the Turkish
representative and single distributor of Ham-Let for valves and fittings, as well
as of Alfa-Laval for sanitary flow equipment.
Since January 2006, the company has manufactured TIG welded stainless
steel pipes in its own facilities, and uses manufacturing processes such
as tricathode TIG welding, outside and inside bead removal, in-line bright
annealing, straightening, surface finishing and tube-end deburring.
Borşen Boru’s test
laboratory is an
important part of its
quality assurance
process.
The company’s
production line uses
two eddy current
systems. The first
test system is used
to detect defects of
incomplete welding;
the second is used
to test whole pipe
sections after the
annealing process.
The company is focused on continuous quality control and improvement.
Some of the standard tests in its new non-destructive and destructive quality
control test laboratory include chemical analysis by spectrometer, surface
roughness test, hardness test, tensile test, shear strength test, flattening test,
flaring test, reverse bending test and hydrostatic test.
Stainless steel tubes produced by Borşen have a producer test and analysis
report according to EN 10204 / 3.1.
Steel grades used include 304, 304L, 316L and SAF2205 (1.4462).
The outside diameter range for pipes is 19-76.1mm, with wall thickness from
0.5 to 4mm, tolerance of D4/T4, and length tolerance of 3-12m.

fitting the tubing ends (two spanners
often need to be used on competitive
valves to ensure that the inserts do not
move).
The 20K H-Series needle valve has
a multi-turn action, which provides a
fine flow control mechanism. Parker’s
Tru-Loc mechanism is used to secure
an integral gland adjuster. The valve’s
metal seat allows operation over a
wide temperature range from -54°C to
+200°C (-65°F to +392°F).
The new valves are available with the
new Phastite connector. Compared with
cone and thread ends, a valve fitted with
Phastite connectors provides a number
of benefits.
It reduces assembly time, as a seal is
made in seconds by simply pushing the
Phastite collar along the tube using a
hand-held hydraulic tool.
As the collar moves, it forces profiles on
the internal sleeve to bite, providing a
high-pressure,leak-tightseal.Incontrast,
cone and thread fittings require time-
consuming precision thread cutting and
coning operations to prepare the tube
for assembly, as well as subsequent
testing. However, conventional cone and
thread style fittings are also available if
required.
Phastite tube ends also allow material
cost and weight savings to be made,
as the connections do not require more
expensive tubing with extra thickness
to accommodate the thread. Phastite
is also resistant to vibration, and does
not require an additional anti-vibration
accessory like cone and thread fittings.
Many applications for the new high-
pressure valves can be found on the
topsides of today’s offshore platforms.
These include hydraulic systems for
wellhead control, emergency shut
down, chemical injection, pumping
packages, gas booster systems, and
test equipment.
