Experienced manufacturer of high-pressure expansion joints for industrial applications
High-pressure expansion joints made of stainless steel are essential components in piping systems as they absorb thermal expansion, vibrations and mechanical movements. Especially in high-pressure applications, their reliability is crucial to minimize operational and safety risks. Comprehensive quality assurance begins with a visual inspection, during which surface defects, weld seams and corrosion points are checked. Dimensional accuracy is also checked to ensure that the expansion joint meets the exact specifications and can be optimally integrated into the pipe system.
HOW CAN WE ASSIST YOU?
Flexible high-pressure expansion joints to reduce vibrations
In addition to structural checks, material testing plays a central role. Spectrochemical analyses are used to determine the alloy composition, while hardness tests and microstructural examinations provide information about the resistance. This is followed by pressure tests to verify the load-bearing capacity of the expansion joint. Here, the component is tested with water or gas above the operating pressure in order to detect leaks or deformations at an early stage. These tests ensure a high level of operational safety in demanding applications.
High-pressure expansion joints for industrial applications
Non-destructive testing methods are used for final quality assurance. Ultrasound and X-ray examinations make internal defects visible, while magnetic particle tests reveal surface cracks. These comprehensive test procedures are essential to ensure the longevity and performance of the high-pressure expansion joints. Manufacturers like HELS rely on these rigorous testing processes to meet the highest standards and deliver reliable solutions for industrial high-pressure systems.
High-pressure expansion joints for power generation
High-pressure expansion joints are essential components in piping systems that compensate for thermal expansion and vibrations under extreme pressure conditions. They are made of high-quality materials such as stainless steel or special alloys to withstand the high loads in various industrial applications. Thanks to their flexibility, high-pressure expansion joints can compensate for axial, lateral and angular movements and thus significantly extend the service life of pipelines.
High-pressure expansion joints for extreme temperature differences
High-pressure expansion joints made of stainless steel play a central role in piping systems by compensating for thermal expansion, vibrations and mechanical loads. Their high load-bearing capacity is particularly essential in high-pressure applications, as failure poses serious safety and operational risks. To ensure consistent quality, these components are subjected to a comprehensive visual inspection and dimensional check. The material analysis includes spectrochemical tests to determine the alloy composition as well as hardness and microstructure tests to assess resistance. Hydrostatic and pneumatic tests are used to validate pressure resistance, simulating loads in excess of the operating pressure. In addition, non-destructive testing methods such as ultrasound and X-ray inspections are used to detect internal and external defects at an early stage. These stringent test procedures ensure a high level of operational reliability and durability in industrial high-pressure applications. Manufacturers such as HELS rely on state-of-the-art testing methods to meet the highest quality and safety standards.

LET US ANSWER THE FREQUENTLY ASKED QUESTIONS
What are the most important areas of application for high-pressure expansion joints?
High-pressure expansion joints are mainly used in piping systems in the petrochemical, power generation, chemical and mechanical engineering industries to reliably absorb movements and pressure peaks and protect system integrity.
Which materials are suitable for the manufacture of high-pressure expansion joints?
High-pressure expansion joints are often made of stainless steel (e.g. AISI 304/321) or special alloys that can withstand high pressure and temperature loads as well as corrosion.
What is the difference between an axial and a lateral high-pressure compensator?
An axial high-pressure expansion joint primarily absorbs longitudinal movements, while a lateral expansion joint is designed for lateral movements in a pipe system in order to meet different requirements.
Why are inner sleeves (liners) important for high-pressure expansion joints?
Inner sleeves protect the bellows of the expansion joint from abrasion by the liquid flow, reduce turbulence and thus contribute to a longer service life and higher efficiency of the expansion joints.
What maximum pressure and temperature limits can high-pressure expansion joints reach?
Depending on the design and material, high-pressure expansion joints can handle pressures up to PN16 and temperatures from -80 °C to +427 °C, with specialized expansion joints available for even higher requirements.
