Category Gateways
BTPS manufactures two primary categories of industrial cylinders. The DA series utilizes a highly specialized porous mass for safe acetylene storage, while the RG series is optimized for diverse refrigerant containment at varying pressures. Both series conform strictly to BIS standards.
Dissolved Acetylene (DA) Cylinders
SERIES A-900 | IS 7312
Welded and seamless DA cylinders integrated with monolithic calcium silicate porous mass (90–92% porosity) and Acetone solvent for stable gas containment at 16 kgf/cm² working pressure.
Refrigerant Gas (RG) Cylinders
SERIES R-200 | IS 3196 (PART 2)
Two-piece and three-piece welded containers constructed from JSW IS 6240 or IS 15914 high-tensile steel, engineered for eco-efficient refrigerants up to 70 kgf/cm² hydrostatic test pressure.

📘 What standards govern BTPS Dissolved Acetylene and Refrigerant Gas cylinders?
📘 What standards govern BTPS Dissolved Acetylene and Refrigerant Gas cylinders?
Dissolved Acetylene (DA) cylinders are manufactured under Bureau of Indian Standards IS 7312, while Refrigerant Gas (RG) cylinders adhere to IS 3196 (Part 2) using IS 6240 or high-test IS 15914 steel. All models receive mandatory statutory approvals from PESO / CCOE, Government of India.
🧪 What is the hydrostatic test pressure difference between Standard and HT Refrigerant cylinders?
🧪 What is the hydrostatic test pressure difference between Standard and HT Refrigerant cylinders?
Standard RG cylinders (5.6L to 68L) possess hydrostatic test pressures between 45 and 50 kgf/cm² for gases like R-134a and R-22. High Test (HT) series cylinders utilize micro-alloyed IS 15914 steel to achieve a 70 kgf/cm² hydrostatic test pressure and 46.67 kgf/cm² working pressure for eco-efficient refrigerants like R-410a, R-32, and R-290.
