We have over 50,000sqft of state of the art, in-house (covered) manufacturing facilities where we process all orders in full compliance with our ISO 9001:2012 business management system.
Process equipment from stainless steel, alloy C276 (Hastelloy), titanium and many other materials and grades is manufactured in-house to exacting international quality standards including ISO, BSEN, DIN EN ISO 28-721 and ASME VIII.
We conduct rigorous inspection regimes throughout the manufacturing process, starting with recieving the raw material and ensuring full material traceability throughout the manufacturing process.
S2 has developed a skilled fabrication workforce certified to the latest ISO and ASME standards who are capable of manufacturing and fabricating products to tight tolerances and international welding specifications. Our coded welders create the base fabrication which is then expertly finished to ensure no surface imperfections.
After fabrication and machining, all welds are subjected to Non-Destructive Testing (NDT) in accordance with latest ASME and international pressure vessel standards, to ensure joint integrity.
S2 has in-house CNC laser cutting machines to ensure accurate profiling and cutting of materials prior to bending and shaping.
High precision, laser cut sheet steel helps to ensure fabricated panels align perfectly, which in turn helps to ensure welded joint integrity.
S2 has a range of in-house semi automatic presses, bending machines and forming tools to accurately produce large cylindrical and curved components as found in vessel design.
This shaping and forming equipment, together with our CNC laser profile cutting machine, helps to ensure excellent material/part fitment for high quality joint/welding integrity.
After fabrication, depending on the complexity of the product or as outlined in the design specification, the product can be then stress releived/normalised using the in-house heat treatment facilities of S2's sister company.
Our in-house/group heat treatment capabilities include two very large CNC furnaces and two smaller furnaces each capable of operating at temperatures to over 1000 degrees C. As this process is within control of S2, we can reduce delivery lead times and ensure high quality stress relieving of products is conducted correctly, as and when the products design/operational quality plan dictates.
Afterwards, the product is then shot-blasted/de-scaled to ensure all the surfaces are clean for polishing/buffing to cGMP standards.
S2 conduct 100% inspection on all manufactured vessels and pressure containing equipment.
Our inspection process is fully detailed in our ISO 9001:2012 Quality Management System and adhered too at all times given the service criticality of the products we make.
We also welcome client inspection hold points during the manufacturing process, where, at pre-agreed times, client quality engineers can inspect the partly-manufactured products. This is typically required where inspection can not be undertaken when the product is in its final stages (i.e. reviewing the surface finish inside a welded/sealed vessel could be a requested client inspection hold point for example).
