The main feature of Mero system is that it has holes at both end of pipe to let the bolt get into the cone after full hot-dip galvanized processing which the cone itself has been welded to the pipe. Thus, the cross section caused by the hole portion will reduce the pipe area of 15% - 25%. In engineering analysis, the pipe size should be enlarged according to the loses at cross section of hole area.
Space.co._Steel Bottle-Ring Connector System
Space.co._Steel Bottle-Ring connector system is designed to avoid making hole on pipe. After hot-dip galvanized processing, the bolt will come along with MR-nut that locked by conical spring (original Apora’s design) and inserted into plate from outside of pipe.
The MR-nut is made of steel AISI 1045 and pass the hardened process to reach the Grade 8.8 with yield strength of 5600 kg/cm2. Laboratorium testing showed that MR-nut was much stronger than the bolt in carrying tension.
