NoticedCouplingThe calculation formula for the cost-effective material is different for different materials. This point is ignored by many customers. The large benefit derived from decimals, the machinery factory sincerely informs: (1) The calculation formula for No. 45 steel is "diameter x diameter x length x 0.00617. 2" The unit is millimeters, which is a kilogram of one meter. (304) 0.00623 stainless steel material is "diameter x diameter x length x XNUMX" which is the weight of one meter of stainless steel.Don’t look at the ten-thousandth place after the decimal point, which is not worth mentioning. It directly affects the big benefits. Its data is directly related toThe cost of the couplingFor example, in the same lesson, the difference between No. 45 and 304 stainless steel materials of one meter is 1.2 kilograms.Plum coupling,smallFlange coupling,smallDiaphragm couplingAnd other products.Welcome customers to come and discuss!
