we normally export to other customers around 30-50 containers per month.
Since 2001 year, we established our factory and make different cylinders . And we have more than 10 years experience producing and export.Our most customers are from asian and middle east country.
We always keep high quality as our first aim, so we use thicker valve and thicker cylinder than others. Thicker valve and high quality valve is very important to keep the cylinder safe and long time life. Cylinder thicker also the most important to keep the pressure . Thicker brass valve and lighter valve prices differ much.
For top rank qualified cylinders most important process is Normalizing treatment , burst press test and hydraulic and tightness test. etc
