Elastomers and thermoplastics are commonly employed in oil and gas applications as seals, gaskets, flowlines, pipe liners and are expected to perform reliably for 20 years or more once in service. Therefore choosing the right polymeric material which can withstand and perform under such harsh environmental conditions is a primary requirement for anyone who supplies these materials to the Oil & Gas sector.  


Element offers a wide range of testing for the qualification and compatibility of polymeric materials (elastomers, thermoplastics and composites) exposed to production fluids at high pressure and high temperatures (HPHT) from our world class polymer testing facilities in Hitchin, UK and Houston, TX, USA.  

The testing services we offer include: 

  • Exposure to sweet and sour fluids, brines and other treatment fluids 
  • Rapid Gas Decompression (RGD) (also known as explosive decompression) under both sweet and sour environments 
  • Accelerated thermal and chemical ageing 
  • Service life estimation using Arrhenius and time temperature superposition (WLF) approaches 

With over 90 dedicated test stations offering autoclave/pressure vessels with remote control and monitoring of temperature and pressure, Element is in a unique position to provide quick turn around and short lead times to its clients. 

The HPHT exposure service is complemented by Element’s fully equipped mechanical testing and thermal analysis testing facilities to characterize the material behaviour both pre- and post-exposure, to quantify the influence of exposure on material performance.  

The mechanical tests (tension, compression, creep, stress relaxation and fatigue) we offer can be performed up to loads of 250 kN and across a temperature range of -190 to 250°C.  

Thermal analysis Differential Scanning Calorimetry (DSC), Dynamic Mechanical Analysis (DMA), Thermo Mechanical Analysis (TMA), Thermogravimetric Analysis (TGA), Gas Chromotography (GC) and thermal conductivity measurement capabilities and services are also available from both our Hitchin and Houston laboratories. 

Tests can be performed to the ISO, ASTM, API and EN standards.


SERVICE

Sour Fluid Testing Services

Element has unique Sour Gas Laboratories capable of pressurizing sour gas mixtures to 300 bar, with dedicated sour boosting pump and performing sour gas exposure of elastomers, thermoplastics and composites. These tests give insight into the performance of materials and how they degrade in the chemically hostile sour fluids encountered in the Oil &Gas Sector.

SERVICE

Sweet Fluid Testing Services

Element has a comprehensive range of Sweet Fluid Testing Service that provide detailed insight into the performance of elastomeric and thermoplastic materials and how they change in a variety of both liquid and gaseous environments in the Oil & Gas sector
