amtec Test Rigs for Gaskets

The function of gasketed joints is significantly determined by the properties of the gasket. These are necessary for both the selection of a suitable gasket and the required proof of tightness and integrity. Additionally, these characteristics are required for quality assurance purposes by the gasket manufacturers.

The most important properties are summarized in a set of (standardized) gasket factors.

AMTEC developed a series of test rigs to determine gasket properties – accurately and cost-effectively. Tests can be performed according to national and international standards as well as according to user-defined procedures.

multifunctional test rig TEMES fl.ai1 (all in one)

Our multifunctional gasket test rig TEMESfl.ai1 provides

  • compression tests
  • compressive creep testing
  • creep/relaxation testing
  • leakage testing

at room temperature or elevated temperature, as well as under load or internal pressure.

The test rig can be operated both manually and fully automatically – which represents a decisive advantage for long testing periods.

test rig for creep/relaxation testing: TEMES fl.relax

We developed the TEMESfl.relax test rig especially for creep/relaxation testing to shorten the time-consuming investigation of various parameters (load, temperature, stiffness) by using several test rigs.

test rig to investigate gasket quality: TEMES ta.luft

The TEMESta.luft test rig is designed for component testing of real flanged connections to investigate gasket quality in terms of the TA Luft (the German Clean Air Act). Here, the sealing behaviour is determined after a previous exposure to temperature.

testing device to test flange joints and valves for their fire resistance: TEMES fire.safe

The testing device TEMESfire.safe is engineered to test flanged joints and valves for their fire resistance. With this device, user-defined test procedures or tests according to EN ISO 10497, BS 6755-2, API 607, API 6FA or API 6FB can be conducted.

KLINGER Test Rigs

Klinger test rig

 
In 2006, we officially took over the support for Klinger testing presses. We carry out maintenance and repair and we offer upgrading of testing equipment with modern hardware and software.

Test Rigs for Packings

Integrity and tightness of stuffing box packings (valve stem seals) has to be safeguarded during the entire life cycle.

The first step to achieve this is done by selecting the materials. Regarding the selection of the most suitable packing material, material characteristics have to be known in detail. Additionally, material characteristics are required to determine the prestress which has to be applied during assembly (tightening torque) and for tightness analysis as well as for the calculation of the friction forces.

Characteristic material properties of packing materials are:

  • deformation behavior
  • tightness behavior
  • friction behavior

and:

  • resistance against wear
  • resistance against corrosion
  • long-term performance

amtec NA developed test rigs for all relevant characteristics of stuffing box packings. These test rigs are ideal tools for product development and quality control for packing material developers and for end users who operate a lot of valves in their plants.

TEMES fl.ai1

Universal test rig for stuffing box packings

The test rig TEMESstb.freak provides

  • friction tests at room temperature as well as at elevated temperatures
  • leakage tests
  • long term tests

The test rig can be operated manually and fully automaticly - an advantage regarding long test duration

The core of this test rig is the simulation of a stuffing box packing / valve stem interaction.

 

Testing Equipment for Valves

Integrity, function and tightness valves have to be safeguarded during the entire life cycle.

After the selection of suitable packing materials for the stem seal and suitable sealing materials for the body seal, the fully assembled valves must be subjected to various measuring, testing and qualification procedures. There are different test standards for this, which pursue different goals. like

  • classification and qualification procedures for type testing or
  • production-accompanying acceptance tests

We have developed test benches for these valve tests. These test benches represent an ideal, sophisticated tool for various approval tests or, more generally, for quality control purposes.

 

TEMES fl.ai1

Universal Valve Test Rig

TEMESvalve.teq allows you to carry out experiments with

  • mechanical cycles,
  • temperature cycles and
  • leak tests.

The test stand can be run manually and fully automatically – a crucial advantage for long test times.

Standardized test procedures such as e.g. according to

  • API and ISO standards

can be carried out in this test rig, both with helium and with methane as the test medium.
