Three-sealing screws calculate how many customers the price at the time of purchase seal screw, usually thought about this question: sealing screw price is how to calculate it? In fact that is difficult is not difficult, as long as the seal screw split open view, but it is still a good calculation. We all know about the screw seal is divided into two: the old-fashioned three-sealing screws and screw seal, in fact, the principles are the same algorithm. Let's look at the old sealing screw, screw sealing old prices, mainly composed of three parts: a light pole, sealing sheet, positioning pieces (including electricity, welding, manual, etc.), in which the sealing screw price from the determining factor is the diameter and length of the light bar. Three-sealing screws price, is largely composed of three parts: the inner and outer pole, sealing films and female connectors (including electricity Yancheng pull the screw on the supply of labor, etc.) Yancheng for pulling the screw, in which the three-sealing Screw play a decisive role in the internal and external diameter and length of the rod. Of course, this price refers only to seal the screw itself Yancheng price for pulling screw specifications, are not included in the price of nuts and freight, taxes, etc., so the costing of time, to consider all aspects of a comprehensive, minimize cost overruns the occurrence. This article comes from sealing screw manufacturer - Nanjing shuangxing screw strength of concrete pouring, etc. 50% after the start of the screw loose screw inside and outside to take  strength of 100% after cutting the ends of the screw. Cut the tip of the screw should be preceded by a drill to screw seal sealing the ends of the plastic ring chiseled. Then start cutting screw. Du decided not reached due to the strength of the concrete to form removal or cutting the seal screw loose screw and pull the screw on the wholesale price of Yancheng later affect seepage, screw site. After the end of the screw rod seal cut end with a rust screw ends of brush twice, watering wet grout brush twice with 1:2 waterproof cement mortar fill the screw holes twice, one week conservation. Inspection and acceptance: After sealing screw installed, should be self-test, check there are no welds is not full of the Department, does not meet the requirements of rework processing. Whether the screw in the correct position. After passing the examination, inspection and acceptance report supervising engineer.
