Contract
Leak Testing Service for Production Parts
Do
you need a part leak testing?
TQC is able to offer
contract leak testing services for production parts where the investment
in instrumentation is not justifiable. TQC do not carry out site
testing of large tanks and pipe work. Our resourceful engineering
staff can develop and write test specifications and procedures to
cover any critical testing requirement.
| The
service is used by Clients who: |
|
|
- Are only
producing a small batch of parts
- Produce
regular batches of small parts that do not want to make
the investment in an in-house system
- Need to
prototype and develop the design of products requiring sealing.
- Are required
to test products to a specific leak test standard beyond
that of the equipment at the Client.
|
|
 |
| Typical
examples are: |
|
|
- Machined
components - pressure & leak testing
- Fabrications
that need helium testing.
- Medical
devices in development.
- Small quantities
of exhaust pipes for specialist vintage cars.
- Bottle closure
development.
- Under bonnet
and engine parts. High performance racing brake parts.
- TQC can
also provide technical guidance and advice on sealing techniques
and sealing materials

TQC standard equipment
includes a full set of calibrated, traceable leak testing instrumentation
(NIST, NAMAS) available for leak testing small quantity batches
of parts. Our capability covers an extensive range of pressures
from high vacuum to 6 bar. Typically, using air decay, leaks of
10 mm3.sec-1 can be found, using helium leaks down to 1x10-8 mbar.l.sec-1
can be identified.
Higher proof test pressures
of up to 1095 bar can be accommodated by special arrangement and
review of safety.
The techniques available
are differential pressure air decay and helium tracer gas testing
services. These techniques include helium spraying and helium sniffing
to locate leaks.
In simple terms, the
sample parts need to be connected to a test instrument. TQC has
equipment available for this including standard connectors and test
chambers and the ability to manufacture sealing plates and bespoke
sealing arrangements as required.
- Connectors. TQC
have a range of standard automatic connectors to connect up to
ports and stub pipes. TQC also has an extensive range of standard
fittings on hand to connect up to and blank off parts for testing.
- Sealing plates
and sealing fixtures. TQC has an in-house workshop able to manufacture
special connectors and bespoke sealing arrangements.
- Test chambers.
TQC has a number of overpressure and vacuum chambers available.
- Leak testing instrumentation
and apparatus. TQC has a range of pressurising and vacuum generation
equipment available.
- Pressurised air
and helium on hand
- Experienced leak
test technicians.
- Providing test
and calibration reports where necessary.
- Leak location
and rectification is available.
Where possible TQC will
use standard reusable parts to make the test as economical as possible.
Typically it takes a couple of weeks to assemble the parts and perform
the first tests, this can be shorter if all the equipment is standard
but a little longer where special parts have to be manufactured.
