PURPOSE: A block assembly for indicating the kind of gas in gas pipes and maintaining the distance are provided to keep the gas pipes at constant intervals by inserting the gas pipes in openings of circular section. CONSTITUTION: A block assembly for indicating the kind of gas in gas pipes and maintaining the distance comprises an indicator block(130), a plurality of top and bottom blocks(120,110), and a plurality of vibration-proof sheets. The indicator block indicates the name of gas flowing in each gas pipe(200). The top block has a insertion groove(125) in which the indicator block is detachably inserted, a first semicircular section grooves(126), a first coupling groove, a through-hole(124), and a handle groove(123). The bottom block has a second semicircular section groove(116) and a first coupling projection. The vibration-proof sheet is attached to the peripheral surfaces of the first and the second semicircular section groove in order to dampen the vibration of the gas pipes by gas flow.
