The hottest national standard steel barrel closer

  • Detail

National standard: steel drum closer (1)

normal align=left> preface

normal align=left> this standard is not equivalent to iso/dis:2000 steel drum part 3: embedded flange closer system, which revises gb/t steel drum closer for packaging containers and retains the steel bucket closer. The main technical differences between this standard and gb/t are as follows:

normal align=left>1. G41/2 series threads are added

normal align=left>2. TM series threads are canceled

normal a no calibration; ③ It has 8-channel door lock switch control. It has all the requirements specified in this standard, including the type, structural dimension, test method, inspection rules and other requirements of the closer. As a large number of steel buckets are used to contain dangerous chemicals and export products, these requirements are used to ensure the quality of steel buckets and transportation safety
