ISO11439 STANDARD / 145L & 200L / 250 BAR / NATURAL GAS VEHICLE TANK / CNG-1 STEEL CYLINDER FOR CNG VEHICLE FUEL STORAGE

QUICK DETAILS:

Working pressure 250 bar, higher than 200 bar of common CNG cylinders

Very high storage capacity

Special shape design to withstand higher pressure

Made of all 34CrMo steel, strong and safe

Corrosion resistant, high anti-aging ability, strong UV durability

Much higher fatigue lifetime cycles than ISO11439 standard

Meet special requirement of customers from Indonesia

WHY OUR CYLINDERS ARE SAFE:

1. The best raw material: Custom-made steel tube, optimized steel element content ratio

2. The special cylinder bottom & neck design: saucer shape, can withstand higher pressure

3. Steel tube with much more uniform wall thickness, to get rid of extra weight

4. The most advanced heat treatment technology: three times higher fatigue cycles than standards
5. Innovative plastic powder spray technology: stronger and smoother cylinder surface

STRICT QUALITY CONTROL:

We do below to eliminate leakages & other defects:

* Regular inspections & tests required by international standards
* 100% Cylinder bottom leakage test

* 100% Finished product leakage test

* Advanced digital threading machine

* Milling threading technique

* QC inspection after threading

We do below to eliminate cracks & wrinkles

* Cylinder bottom UT detection test

* Cylinder bottom thickness measurement

* 100% wrinkle inspection by endoscope
