We utilize various grades of carbon steel, ensuring suitability for different applications:

ASTM A36/SS400: For general purpose storage of non-corrosive chemicals at ambient temperatures and pressures. These are commonly used for fuel storage and water treatment applications where specific internal corrosion is managed.

ASTM A283 Grade C: Offering improved tensile strength and ductility, suitable for more demanding applications.

ASTM A516 Grades 60/70: These are Pressure Vessel Quality (PVQ) plates specifically designed for moderate and lower temperature service where improved notch toughness is required, and suitable for higher pressure applications. These grades are ideal for pressure vessels that operate under more demanding conditions or require enhanced material integrity for safety, particularly important in regions with temperature variations or seismic activity.

For enhanced corrosion resistance, which is important given Nepal's humid monsoon season and potential for varied atmospheric conditions, robust external and internal coating systems are crucial for the longevity of carbon steel tanks. Externally, multi-layer industrial-grade epoxy or polyurethane paint systems, often with suitable primers, are applied to protect against humidity, UV radiation, and general atmospheric corrosion. Internally, if the stored chemical is corrosive or requires high purity, specialized internal coatings or linings (e.g., epoxy, phenolic, vinyl ester, or rubber linings) are meticulously applied. These coatings provide a critical barrier against chemical attack, significantly extending the tank's service life and minimizing maintenance requirements. Our coating specialists work diligently with clients to recommend and apply the most suitable protective layers, tailored to the specific chemical environment and operational temperatures.

Design and Fabrication:

Our engineering team utilizes advanced design software, ensuring strict compliance with international standards such as API 650 (for atmospheric and low-pressure storage tanks), ASME Boiler and Pressure Vessel Code (BPVC) Section VIII Division 1 (for unfired pressure vessels), and other relevant industry codes. Our fabrication facilities are equipped with state-of-the-art welding equipment and employ highly skilled, certified welders. We adhere to rigorous welding procedures, ensuring structural integrity and longevity:

Submerged Arc Welding (SAW): For high-speed, high-quality welds on thick plates, often used for tank shell seams, providing excellent mechanical properties and efficiency.

Gas Metal Arc Welding (GMAW) / MIG: Versatile for various applications, offering good penetration and deposition rates.

Shielded Metal Arc Welding (SMAW) / Stick Welding: For field welding and repairs, offering flexibility in various positions, which is advantageous for installations in geographically diverse and sometimes remote locations across Nepal.

All welding processes are subject to stringent quality control, including non-destructive testing (NDT) methods such as radiographic testing (RT), ultrasonic testing (UT), magnetic particle testing (MPT), and liquid penetrant testing (LPT) to ensure weld integrity, detect any defects, and verify material soundness. Post-weld heat treatment (PWHT) may also be performed for specific pressure vessel applications to reduce residual stresses and enhance material properties, particularly important for seismic resilience.
