摘要：The aim of the study was to compare the welded and adhesive joints made of polypropylene pipes. The pipes werebutt jointed. Two pipe diameters were used: ø20 mm and ø25 mm. The welded joints were made by hot gas weld-ing, while the adhesive joints were made by two epoxy adhesive compositions. The base for both compositionswas Epidian 6 epoxy resin, which was mixed with IDA and TFF curing agents in the recommended quantitativeratios. The experimental tests consisted in determination and comparison of the strength properties of the madejoints; therefore, the analyzed joints were subjected to the destructive strength tests, which determined their tensilestrength in accordance with the ISO 527–1 standard. On the basis of the obtained results, it was observed thatwelded joints obtained the highest average strength. The lowest strength was characteristic for the adhesive jointsmade with Epidian 6/TFF/100:27 adhesive. The obtained results were subjected to a statistical analysis, whichshowed that the strength of ø20 mm diameter pipe joints did not differ significantly from the strength of ø25 mmdiameter pipe joints, comparing the results for each type of joint with the assumed level of confidence α = 0.05.
