Why can we guarantee the quality of our products:
The cylinder passed the inspection of the state department.
We have advanced cylinder handling equipment, one-time heating to remove moisture, vacuum and other work.So the purity of the CF6 gas is 99.99% in the cylinder.
The filling weight is sufficient.We have filling report for every cylinder.This report will be sent to the customer together with the gas test report.
We have precision testing equipment,and promised every cylinder and gas will be test before the delivery.
