Sealing

Validation and optimization of sealing joints

Pioseal® stands for comprehensive sealing solutions for industrial applications. As an overarching product range, Pioseal® covers all sealing-related topics and combines the key areas of sealing concepts, leak testing, and predictive engineering. Pioseal® combines development, validation, and technical customer consulting into an integrated approach – with the aim of systematically improving sealing points and taking them into account early on in the product development process. 

The sealing function of a joint depends, among other things, on the geometry, material properties, and manufacturing tolerances. Targeted testing and optimization strategies can prevent critical leaks and ensure the long-term reliability of the connection.

The market’s demands

  • Sealing validation 
  • Minimal sealed surface 
  • Corrosion resistance 
  • Sealing as a safety feature 
  • Maximum sealing performance despite minimal permitted surface pressure 
  • Multi-material mix 
  • Flexible adaptability to differing ambient conditions 
  • Repeatability of assembly

ARNOLD provides the solution

Individual sealing systems and testing options

The technical advantages of our testing equipment

  • Individual technical consultation
  • Standardized forms (no exact target leakage required from the customer in advance; internal estimation of the acceptable range available on request)
  • Detailed test report including all necessary parameters
  • Early joint optimization
  • Definition of customized sealing concepts
  • Identification of weak points during leakage detection

Commercial advantages

  • Sealing elements as combination parts
  • Increased product reliability
  • Verifiable improvement in the quality of the joint connection
  • Lower total operating costs through reduction of downtime
  • Minimization of costly rework
  • Reduction of scrap production
