Oil and Gas Maintenance
On Line Leak Sealing Services
,under pressure leak sealing services are provided by the
process, using asbestos-free compounds specially formulated to
suit many different products, has successfully solved leak
problems at oil refineries, oil and gas platforms, chemical
plants, nuclear and conventional power stations, iron and steel
works, pulp and paper mills, food and drink processing plants,
marine and many other industries.
Leaks can be
sealed while plant continues to operate at normal line pressure
and temperature, ranging from 100m bar vacuum to 350 bars.
Specialist techniques which have been developed include methods
for dealing with the particularly difficult problem of oil leaks
from transformers and other equipment, including those from
main, turret and top joints, as well as intricate valves and
irregularly shaped flanges.
On Site Machining
furniture on-site machining services provides portable machines
and skilled technicians to meet a variety of plant maintenance
requirements which call for in-situ machining operations.
Applications covered include flange facing up to 6,096mm (240");
pipe cutting any diameter, pipe end profiling and weld
preparation; drilling in excess of 203mm(8") in diameter and
1,016mm (40") in depth; milling keyway milling and fly cutting;
journal turning over a wide range of diameters on journals with
stepped diameter profiles and ring grooves; tyre grinding on
large diameter rotating plant; line boring in excess of 1,524mm
(60") in diameter; and boring for core removal or machining out
worn pins. Trepanning to larger diameters is also available
using our standard range of equipment.
Safety and Relief Valve Testing
Valve Testing is
patented hydraulic system for on-line testing of safety and
relief valves in steam, water, air, gas and process systems
while the plant continues to operate at normal pressure and
temperature. On-line Valve Testing can also test valves 'cold' when there is
no line pressure.
A remote, multi-pen recorder provides a date marked certified
print-out of the lift pressure. Line pressure at the valve or
valve displacement can also be recorded. Results achieved with
the On-line Valve Testing system are normally within +/- 1% of set pressure
when the valve is tested on-line.
An intrinsically safe On-line Valve Testing unit is now also available which
has been specifically designed for safe operation in potentially
hazardous plant areas.
