We have been in business since 1912. Over the years, we have acquired both expertise and hands-on experience. As a result, we know how to comply with international regulations and offer advice on the optimal design code or material type for your process.
All process equipment is tailored to meet your specs.
In addition to your specs, we mechanically engineer in accordance with many design codes. These include:
Thermal design complies with HRTI regulations; we re-mark materials per LRQA’s G0304 certificate.
Furthermore, we ensure optimal quality by extensively testing our products. For instance, we x-ray the weld seams of our products and perform hydrostatic tests up to pressures of 600 barg.
We also hold several international certifications, including:
Inspections are performed by LRQA, TUV, ABS and Bureau Veritas, among others.
Please note that this list of design codes and certifications is not complete. For more information, read about our Quality System.
Testimony to our customised products is the range of materials we work with. Among these are:
For optimal quality, we separated the work with stainless steel and non-ferrous materials on the one hand and carbon steel on the other. These are carried out in 2 separate hangars.
All materials are processed using multiple specialised welding techniques, including:
The wall thickness of our materials is more varied than that of others, including other Rootselaar Group companies. Combined with our specialised welding techniques, we offer such technical expertise that we are regularly called upon by other Rootselaar Group companies.
