Certificate No.25389Multi-Component Liquid (MCL)
Field Joint Coating
P ipeline Induction Heat Ltd (PIH), a CRC Evans Company is a contracting company specialising in the onsite application of anti-corrosion coatings, heat treatment and other support rvices during construction of onshore and offshore oil, gas and product pipelines.
The pipeline industry is characterid by rapid advances in automatic welding and
factory-applied linepipe coating technologies. Anticipating the trends requires PIH
to undertake innovative rearch and development to provide practical solutions, which satisfy the stringent new standards. This has resulted in an expansion from PIH's traditional induction heating business, into diver activities involving the site application of sophisticated pipeline joint anti-corrosion, thermal insulation and infill coating systems.
As the most experienced independent field joint coating contractor, PIH fully understands the necess
ity for working alongside both main contractors and owners to provide a total project rvice for field joint coating of their pipelines. On time, on budget and to specification are key parameters in the PIH business philosophy. However, this is never allowed to overshadow the primarily important factor of health and safety on construction worksites. PIH places primary focus on achieving zero accidents both in the field and throughout the business operation. As concern within the pipeline industry
becomes ever more focusd on
environmental issues, PIH has worked hard
to develop new technologies and
application systems, which are more
efficient, reduce waste and po less of a
threat to the environment. Collaborating
with the main contractors, PIH has
developed automatic coating machines that
reduce over spray and coating material
loss during application hence reducing if
not eliminating any environmental impact.
Similarly, PIH automatic tape wrap systems
reduce the u of powder technology so
greatly reducing wastage and enhancing
operator safety.
For more than two decades PIH has worked
with more main contractors than any other
independent field joint coating contractor. PIH
has successfully completed millions of pipeline
field joints on every continent working in every
environment. Using skills and experience now
gained by the UK workforce and its partners,
PIH intends to face the future confident in their
无人机干扰
ability to drive the industry forward with new
and innovative techniques in a technology
driven ctor. Safer and more efficient field joint
coating systems being constantly developed
and implemented on projects worldwide with
the aim of providing clients with fully compliant
solutions while maintaining PIH as the world's
pre-eminent field joint coating specialist.
猪原由纪子Services to the Pipeline Industry
"PIH aims to provide the best
specialist pipeline 'field joint'
rvice worldwide, offering
a complete end-to-end
package of total in-hou
design, build and supervisory
control to today's onshore and
offshore pipelay contractor.
We strive to provide the
most reliable, cost effective
solutions within the rigorous
time scales demanded of the
春天的西湖industry, whilst maintaining the
highest quality results.”
There are many different urethane and epoxy bad liquids which offer particular properties appropriate for particular pipeline requirements. In general terms the urethanes produce a fast reacting and flexible coating which can be applied in most climatic conditions with the u of preheating and/or post heating. The liquids will be able to withstand operating temperatures of up to around 90 °C. T ar extended urethanes provide a very economical field joint coating system for u on both 3LPE and 3LPP pipelines. Epoxy bad liquids will offer higher operating temperature compatibility and are hence more widely ud in 3LPP applications.
In order to make the most of the technical benefits of the multi-component liquids available in the market, PIH has designed and developed a family of automatic coating machines. Not only do the
machines meter the individual components of the liquids in the
婚宴流程correct ratio to the spray head, but the on-pipe rotating spray ring applies the material in a consistently even and repeatable manner to the specified
thickness and band width. In this design the consumption of the liquid is reduced to
the absolute minimum since over spray and wastage is virtually eliminated with obvious HSE benefits.
Since the application thickness is directly related to the number of rotations of the machine, once the procedure is proven by pre-production testing, the machine will be pre-programmed for the project and can then be operated by trained personnel under the supervision of PIH technicians.Relatively small coating crews will be required consisting mainly of locally supplied labour, making the u of liquid field joint coating systems very commercially attractive. The equipment can be trace heated to assist with application in low ambient temperature conditions.
The system of automatic spray application of MCL's has proved so successful that the system was approved by T ransco (British Gas) in the UK, as early as 2000 for u on their major FBE coated ov
erland pipelines. Many projects have subquently been completed for T ransco as well as for international clients on major pipeline construction projects.
The PIH automatic system has been refined over many years and now offers very high production rates of up to 350 joints per day by a single crew applying liquids to an overall 1,000 micron thickness and overlap onto the factory coating of 50 mm - 75 mm.
One other advantage of the liquid system is that the backup anti-corrosion system (the cathodic protection system) will not be compromid, hence ensuring a continuous flow of current to any defect location along the pipeline length. Many other field joint coating systems do shield the CP system and hence defect may go undetected leading to rious failure in the anti-corrosion coating system.
