Leading pipe supplier to the Central Asia-China pipeline project
PJSC Khartsyzsk Tube Works, founded in 1898, is involved in the manufacture of pipes
for oil, gas and water pipelines. The company’s production range includes pipes from
406mm to 1,422mm in diameter with wall thickness from 7mm to 32mm. There is a
capability for external anticorrosion polyethylene and internal flow and anticorrosion
epoxy coating.
Khartsyzsk operates a management system certified according to ISO 9001, OHSAS
18001 and ISO 14001. The main preoccupation of the company’s plant is the project
for construction of the Central Asia-China gas pipeline. This project requires pipes with
1,067mm in diameter and wall thickness of 15.9mm and 19.1mm.
In order to carry out this order, the company use high-quality process materials and
advanced technologies both for pipe manufacture and the application of external and
internal coating. A monitoring system for the technological parameters is installed in the
shops to ensure optimum management of all production areas.

Bronx/Taylor-Wilson awarded contract
for pipe finishing equipment
Brushes for pipeline
weld cleaning
Osborn International, Germany, is the
manufacturer of brushes and abrasives
for use in industrial applications. Steel
wire brushes are an ideal solution for the
cleaning of welded seams.
Wire brushes are a cost effective and
practical method for removing welding
cinder and beads that prevent the next seam
from being applied. The use of cellulose
and alkaline electrodes are insignificant,
as a brush will carefully remove all types of
cinder.
A rotating wire brush will provide a clean
welded seam without having to remove up
to 30 per cent of the welding material, as is
inevitable with a grinding disc. Any defects
in the weld seam also become immediately
visible, enabling any rework to be carried
out promptly.
The use of steel wire brushes reduces
the number of seams by a claimed 30-50
per cent, and additional time needed for
resoldering work can be avoided. Osborn
pipeline brushes can be used for weld
cleaning, internal or external cleaning, bevel
end cleaning, removal of insulation coats
and rehabilitation work. They enable long
life, optimal brushing results and safe work.

Bronx/Taylor-Wilson, USA, a leading
manufacturer of straightening and
hydrostatic testing equipment, has recently
won a number of contracts. The company’s
state-of-the-art equipment can be used to
process cold and hot pipes of over 600°C,
thin or thick walled tubes of over 50mm,
and low or high yield strength alloys of over
1000MPa.
The latest contract won by Bronx is from a
new joint venture between a SouthAmerican
company and a Japanese company. As part
of the decision process, stringent testing
required pressures that have never been
accomplished on such high yield equipment
for API standard 5CT/5L product diameter
ranging from 177.8mm to 406.4mm.
The hydrotesters will be designed to
withstand an end load of 8043KN for
406.4mm OD casing. This end load is the
highest of any product that will be tested at
such diameters. The hydrostatic pipe tester
will include the main machine and auxiliaries
and will incorporate the Bronx/Taylor-Wilson
proven collapsing sealing between the tube
and testing head which has a lifetime of
10,000 testing times per piece.
The tester is enclosed in a safety protective
hood that includes lifting devices for tool
changing and equipment with the possibility
to place the tools outside of the protective
hood. The controls are equipped with
a pressure recorder to store the entire
procedure of the testing from water filling to
pressure build up, to pressure-to-pressure
releasing and the time of pressure testing.
The data can be stored digitally and on paper,
and individually sorted according to the
time, lot, shift, product standard, outer dia-
meter, wall thickness, and steel grade (steel
type). The fully automatic machine can also
be manually operated by push button.
The hydrostatic pipe tester will be equipped
with an automatic self-checking function,
fully automatic control, communication
with upstream and downstream equipment
and interfaces for checking signals. The
machine has functions to transfer the
necessary information of production and
process to an upper level computer.
Bronx/Taylor-Wilson will also supply two
6.CR.11 pipe-straightening machines.
These machines will process a diameter
range of 177.8mm to 406.4mm diameter
at yield strengths above 165,000psi. This
particular design of straightening machine
is an example of the design that BTW offers
to the market.
The Bronx/Taylor-Wilson 6.CR. 11 six-roll
design is used to straighten the top quality
API and GOST quality pipes in the most
arduous of mill conditions. The machines
offer features including a hydraulic lift for
ease of tube entry and electronic pressure
sensing load cells for an accurate indication
of straightening loads. In addition, the
machines are supplied with the patented
Compass computer aided setting system.
