ISO9809 standard CNG steel cylinder is produced from seamless steel pipe, and is designed with high working pressure up to 250bar, so it can be assembled into cascade, used for CNG storage in CNG filling stations, and mobile gas supply module for factories and other places that need natural gas but without underground gas supply. Its low cost makes it the most perfect idea for CNG ground storage applications.
All of our ISO9809 standard natural gas storage cylinders are manufactured and tested 100%, and third party inspection is available if customers need it.
We have more than 15 years manufacturing experience, and can design any kind of CNG cascade according to customers' requirements. Just advise your technical requirement and we will provide you the best CNG cascade solution.
Why Our Cylindersfe Are Safe:
1. We require tailored steel tube, to ensure perfect steel element ratio and mechanical properties of the CNG tanks.
2. We perform several times experiments and verifications to develop unique heat treatment
temperature for each batch of steel tube, in order to have excellent heat treatment performance
3. > 10 items of extra tests and inspections beyond international standards
4. Internal QC criteria stricter than international standardstrict QC Standards:
