The bundles manufactured by us meet the requirements of PN-EN ISO 10961:2012, ADR 2017, requirements of Directive 2010/35/EU, are designed in accordance with the guidelines contained in PN-EN 13480 and other industry standards
Bundle baskets are made of hot-rolled profiles and sections, joined by MAG and TIG welding, where all welds meet at least the acceptance level C according to PN-EN 5817: 2007. In addition, the welds in the basket and the collector are subjected to non-destructive visual, magnetic/powder and X-ray examinations, thanks to which the structure of the basket as well as the cylinder collector are characterized by high quality of workmanship, which is constantly controlled and supervised throughout the production process.
As a standard, the baskets are protected against corrosion by hot-dip galvanizing, and on customer's request they can be powder-coated in any color from the RAL palette.
Cylinder bundle collectors
Cylinder bundle collectors are made of 304/304L grade stainless steel pipes and fittings and from brass as standard. On customer's request it is possible to make collectors from other steel grades, e.g. 316, 321.
The pipe joints are welded orbitally, which guarantees high quality and almost 100% repeatability of the joints.
For orbital welding we use closed heads and welding sources from the renowned company Orbitec. Our qualified staff has extensive experience and the necessary authorizations to perform this type of work, which guarantees the highest quality of the collector.
Each collector is subjected to a hydraulic strength test and the course of the test is recorded using a measuring device with current calibration certificates. The tests are performed and supervised by qualified personnel with extensive experience and appropriate authorizations to perform such tests.
After the hydraulic tests, the whole collector is dried, and at the customer's request, we carry out a dew point measurement and attach an appropriate protocol from the measurements.
In addition, we perform pneumatic pressure tests for the finished bundle at a pressure equal to the working pressure of the bundle, i.e. 200 or 300 bar, depending on the bundle model.
All test and measurement results are included in the protocols which are attached to the passport of each bundle.
