Flexible pipe

Our company”The right connection...

STENFLEX compensators areused for

■ compensation of movement

■ vibration absorption

■ noise absorption and

■ tension reduction

in pipeline systems.

Furthermore, they can be used as

■ compensators for installationinaccuracies

Our phone, fax and e-mail are always available to process urgent orders

and queries, or deal with possible problems that may arise.

We want you to know more

Our experts will gladly pass on their expertise about flexible pipe con-

nections in seminars and training courses at STENFLEX or the client’s

premises.

Only adequate planning will ensure that equipment and machinery can

work perfectly - avoiding costly downtimes. Our training courses and

seminars can help to ensure that

your project planners and engi-

neers are up-to-date with state-of-

the-art engineering.

It's best to make sure

STENFLEX flexible pipe connec-

tions: top-grade products that are

practically maintenance-free; safe

and dependable – with a long ser-

vice life.

One of our STENFLEX services:

regular inspection of installed

compensators within your plant.

This will promote the efficiency

and safety of your equipment.

Early indicators of change can be identified. If component replacement

is indicated we shall make a firm quotation. This will ensure that only

STENFLEX original replacement parts - subject to strict quality control

and testing - are used.

Through our international subsidiaries and agencies we can guarantee

quick on-site help and prompt spare parts delivery.

On delivery our products are accompanied by detailed installation

instructions in various languages. Furthermore, our consignments are

provided with labels, special instructions and warning notices.

Engineering and planning bureaus can access our article data, product

range and price list on disk as a data record at an early project stage.

Clearly this will simplify your choice of STENFLEX flexible pipe connec-

tions.

STENFLEX offers regular inspections to ensure

reliable plant operation
