The InspecTech® Off-Line UT Weld Inspection system is normally integrated with the
material handling equipment used at the finishing floor.
This UT system requires an overhead transport system with drive and logic controls
such that when product is presented with the weld line accurately positioned, the
test head can travel the length of the weld area to perform the test.
Product must be straight within specification, and the transport system must be aligned
precisely for the equipment to function properly.
Welding defects that are detected, cause alarms to sound and the affected spot can
be spray marked immediately adjacent to defect areas. An alternate arrangement stops
and re-tests any suspect areas and requires operator intervention to decide accept/reject
InspecTech can offer a basic UT system that consists of the test head, the electronic
system and the travelling interconnect cables & hoses. These items, when supplied
by InspecTech are ready to install on the customer's existing overhead track and
Alternatively, InspecTech can also provide an extended system, including overhead
truss, track, carriage and carriage drive system, plus all the required logic controls
and the operator's console. The operator's console in this instance includes all
of the switches and indicators that are needed for the pipe handling equipment, ready
for wiring to the customer's own handling system.
Test systems can include 4, 6, 8 or more transducers, arranged in any combination
to detect longitudinal, transverse or lamination defects, using shear wave or longitudinal
wave methods as appropriate. Choice of the number and arrangement of transducers
is between Supplier and Customer, and it is often governed by code requirements.
Optionally, transducers for Ultrasonic End Zone lamination detection may be installed
on the same off-line test head, or work in conjunction with other test heads working
in parallel on the same overhead truss.
The scope of supply can include all of the items required, or just some of them,
and customers can choose to configure their own test track systems. InspecTech can
provide design and engineering for local fabrication of structural elements upon
InspecTech® Off-Line Ultrasonic Test Systems are specially designed and configured
to inspect the entire length of a weld seam in a tubular product. This form of testing
is normally required for code compliances such as API and ISO.
Testing is similar to InspecTech's On-Line Test System, but the test head is configured
differently and more mechanization is required.
This test unit an overhead carriage, which travels above a stationary pipe. This
arrangement is the usual method of choice. An alternative method, involving a stationary
test head with the pipe being conveyed underneath is also available.
