TI-004    Expansion Joint Questionaire
The TI-004 Spec with our expansion joint questionnaire provides the support needed for a proper design layout for our expansion joints

How it shouldn’t be done!

How you can save money
Incorrect interpretation due to missing information Professional Design

Wrong designed belt type expansion joint without pre-formed convolution
Incorrect pre-insulation leads to premature damage to the expansion joint: Service life only three weeks Professional design:
Belt type expansion joint with pre-formed convolution and application-specific pre-insulation: Service life 6 years
The complete specification of all operating parameters guarantee a correct design layout.
In the video: Unknown pressure fluctuations / pulsations on a tissue expansion joint, which can lead to premature wear.

The expansion joint questionnaire TI-004 provided by the RAL Quality Assurance Association will help you with your inquiry / order and will ask all relevant operating parameters.

TI-008   Bolting connections for soft material Expansion Joints

The TI-007 gives you the necessary information for the correct Bolt requirements

How it shouldn’t be done!

How to save money

Tightening torques for bolts not followed: Therefore loose screw connections!
This leads to leaks and leakage of medium.		 Observing the correct tightening torques is a prerequisite for achieving sufficient tightness.

TI-008   Storage, Packaging and Transportion of soft material Expansion Joints

For proper storage, packaging and transportation information, see TI-008.

How it shouldn’t be done!

How to save money
Wrong storage:
Not following the proper storage instructions:
Store absolutely dry and remove shortly before installation.
Professional Storage

Remove packaging just before installation!
Be sure to follow notes and pictograms !!
Lifting of soft material expansion joints only at the designated attachment points, not at the mounting brackets! (In this example the crane eyelets were not used.) Using suitable load handling equipment and in compliance with the relevant safety regulations.

TI-009   Planning of Assemblies – soft Material Expansion Joints
All the necessary information for proper planning the assembly ,see TI-009

How it shouldn’t be done!

How to save money
Missing holes in the corner radius and Bent steel parts can lead to leaks. Holes in the corner radius achieve optimum tightness.
Error during the assembly:
Support touches the expansion joints. Possible premature failure of the expansion joint.		 Good organization and planning of the assembly ensures a smooth assembly process and that everything is available at the right time.
Support touches the expansion joint

TI-010 Assembly of soft material Expansion Joints

Correctly installed back up bars (diagonal or straight version is permitted)

How it shouldn’t be done!

How to save money
Orientation of the screws, distance of the terminal strip segments and clamping bars
without an impact plate		 Proper orientation of the screws.
Correct Distance of back up bars.
Back up bars with shims underneath.
Holes and Fasteners in the proper horizontal location with each other
Burning of a mounting bracket – causing damage to the expansion joint Correctly installed back up bars (diagonal or straight version is permitted)
Damage caused by heat and fire
Screws are installed in the wrong direction!
Back up bars without shims.

TI-011 Insulation requirements for soft material expansion joints

The TI-011 can protect you from damage caused by incorrect or faulty installed insulation in the expansion joint area.

How it shouldn’t be done!

How to save money
Wrong protection against touching the expansion joint.
Insulation prevents heat dissipation.		 Touch protection with proper
Convection and heat dissipation
After removing the touch protection: Wrong connection for already existing insulation Professional execution:
New insulation connection all the way up to the flange, free convection
Semi-insulated fabric expansion joint. This prevents convection and heat accumulation.
Additional risk of damage from sharp-edged sheets.
Heat radiation can lead to damage to the soft material expansoin joint due to incorrect installed external insulation.

TI-012 Maintenance work on soft material expansion joints as part of the plant overhaul

The TI-012 can help you increase the life expectance of the soft material expansion joints and protect you from premature failure.

How it shouldn’t be done!

Chaos during installation can lead to damage to the expansnoin joint

TI-013 Tolerances for connection parts and installation dimensions for soft material expansion joints

How it shouldn’t be done!

How to save money

Lateral misalignment already incorporated by the manufacturer reduces stress and increases service life. For this, the offsets must be measured as accurately as possible.
Überschreitung der lateralen Exceeding the lateral mounting tolerances

TI-015   Safety management of soft material Expansion Joints

The TI-015 gives you important information about the safe handling of expansion joints

How it shouldn’t be done!

How to save money
Mounting point is not secured with proper scaffolding.
As a result, there is a high risk of accidents and injury.		 Assembly site is equipped with proper scaffolding. Workers wear their personal protective equipment PPE.
This ensures a safe, quick and correct installation.
This saves time, money and nerves
Risk of falling!
