Construction and Design of Pressure Vessels

Design Craft LTD specializes in the engineering, design, and fabrication of high-performance pressure vessels tailored for a wide range of industries, including oil refineries, gas processing plants, petrochemical complexes, pharmaceutical facilities, food industries, power generation units, water treatment plants, and medical applications.

Our vessels are engineered with precision, safety, and long-term reliability, meeting the most demanding operational requirements such as high pressure, high temperature, corrosive environments, and cyclic loading conditions.

We design and manufacture all vessels in strict compliance with internationally recognized standards, including:

ASME Boiler & Pressure Vessel Code (BPVC Section VIII Division 1)

API 650 – Welded Tanks for Oil Storage

API 620 – Low-Pressure Storage Tanks

EN 13445 – Unfired Pressure Vessels

PD 5500 – Pressure Vessel Design Code

AWS D1.1 Structural Welding Code

Our engineering team applies advanced design methodologies, including stress analysis, FEA (Finite Element Analysis), nozzle load assessment, vibration checks, and saddle/skirt support design, ensuring the vessel performs safely under all intended operating conditions.

Air receiver tanks

Air receiver tanks (or compressed air storage tanks) are critical components in compressed air systems, serving as buffers to store compressed air and stabilize pressure fluctuations. They improve efficiency, reduce compressor cycling, and ensure a steady air supply.

. Common Applications

•Manufacturing & Automation (Pneumatic tools, assembly lines)

•HVAC Systems (Air control units)

•Construction & Mining (Jackhammers, drills)

•Food & Beverage Industry (Packaging, cleaning)

•Medical & Dental (Air supply for equipment)

Power Plants & Oil & Gas (Instrument air systems) Key Functions & Usages

Air receiver tanks serve multiple purposes:

A. Pressure Stabilization

•Reduces pressure fluctuations (“pulsation dampening”).

•Prevents frequent compressor cycling, extending its lifespan.

B. Condensate Separation

•Allows moisture and oil to settle, reducing contamination in the air system.

•Equipped with drain valves to remove accumulated liquids.

C. Emergency Air Supply

•Acts as a backup during power outages or compressor failures.

D. Energy Efficiency

•Stores excess compressed air, reducing the need for constant compressor operation.

•Lowers energy consumption by optimizing load/unload cycles.
