Karlsen, Ø., & Lemu, H. G. (2021). Questionnarie-based survey of experiences with the use of expanding PIN systems in mechanical joints. Results in Engineering, 9, 100212. 10.1016/j.rineng.2021.100212Abstract
In this paper, experiences with the use of expanding pins in mechanical joints in different equipment are investigated through a questionnaire-based survey, where six different sections are highlighted; Size of company, Company profile, Experience with expanding pins, Market and equipment, Pin source and Effects and consequences of applying expanding pin solutions. The responses on the survey came from 10 different countries, with the main segments being Offshore oil & gas, Maritime/ships and Construction/earth moving. In total 256 potential responders received the questionnaire, divided into 140 Norwegian based companies and 116 non-Norwegian. Expanding pin systems are clearly seen as technically better pin solutions which protect better both people and equipment, and the non-Norwegian companies are reporting better experiences with expanding pins, in general, compared to the Norwegians, and recognize more the importance of the economic effects of applying expanding pins, compared to standard cylindrical pins.
