Pressure Vessels as per design code
We design and manufacture pressure vessels for a wide range of applications, from compressed air storage to complex chemical processing. Fabricated under our ASME 'U' Stamp authorization, each vessel is a testament to code-compliant engineering.
- Custom Engineering & Design: Our process begins with rigorous calculations using software like PV Elite or COMPRESS, adhering to ASME Boiler and Pressure Vessel Code, Section VIII, Division 1. We consider design pressure, temperature, material selection, corrosion allowances, and all load cases.
- Material Expertise: We work with carbon steel (SA-516 Gr. 70), stainless steels (304/316/L), duplex, and clad materials. All plates, heads, and nozzles come with full Mill Test Certificates (MTCs) and are traceable throughout fabrication.
- Precision Fabrication & Welding: Components are precisely formed using CNC cutting and rolling machines. Welding is performed by ASME-certified welders following qualified Welding Procedure Specifications (WPS), with techniques including Submerged Arc Welding (SAW) for longitudinal seams.
- Post-Weld Heat Treatment (PWHT): We perform stress relieving in our on-site furnaces as required by code to ensure dimensional stability and relieve residual stresses.
- Comprehensive Certification: Each vessel is documented with a formal ASME Data Report Form U-1 and a Manufacturer's Data Report (MDR), providing a complete life-cycle record.
Common Applications: Air receivers, heat exchangers, reactors, separators, scrubbers, and columns for the oil & gas, chemical, pharmaceutical, and food & beverage industries.
Custom-Engineered Storage Tanks
We build robust storage solutions for liquids, chemicals, and gases, designed to API standards or client-specific specifications for above-ground, atmospheric, and low-pressure service.
| Category | Details |
|---|---|
| API & Industry Standard Compliance |
API 650: Welded tanks for oil storage. API 620: Design and construction of large, welded, low-pressure storage tanks. AWWA D100: Welded carbon steel tanks for water storage. ASME Sec VIII D1: Design, fabrication, inspection, testing, and certification of pressure vessels. |
| Tank Design Varieties |
Cone Roof Tanks: Standard for many liquid storage applications. Floating Roof Tanks: For minimizing vapor loss (internal or external floats). Horizontal Pressure Tanks: For LPG, propane, butane, and other pressurized products. |
| Advanced Fabrication & Erection | We utilize the sweep-and-pick method or jump-form techniques for large field-erected tanks. All seams are meticulously welded and inspected. |
| Ancillary Systems | We can design and fit accessories including manways, nozzles, ladders, platforms, gauges, and heating/cooling coils. |
Durable Industrial Silos
Our silos are engineered for the efficient, safe, and reliable storage of bulk solids like grains, cement, fly ash, plastic granules, and other powdered or granular materials.
- Design for Flow & Integrity: We design to prevent bridging, rat-holing, and segregation. Options include flat-bottom, hopper-bottom, and cone-bottom designs. Calculations account for static and dynamic powder pressures.
- Material & Construction: Fabricated from high-quality carbon steel or stainless steel, with seams continuously welded for strength and to maintain an airtight/weatherproof environment.
- Specialized Internals: We install necessary internals such as breaker bars, vibrators (external), fluidizing pads, and level indicators to ensure consistent material flow and accurate inventory management.
- Surface Protection: Internal and external coatings are selected based on the stored material—from epoxy and polyurethane to specialized food-grade or abrasion-resistant linings.
Precision Engineered Hoppers
We fabricate hoppers that are integral to smooth process flow, designed for reliable discharge without blockages, for integration with conveyor systems, reactors, or packaging lines.
- Mass Flow & Funnel Flow Design: We engineer hopper geometry (cone angle, outlet size) to ensure the required flow pattern—preventing segregation, ensuring first-in-first-out discharge, and eliminating dead zones.
- Discharge Aids Integration: Hoppers are designed to seamlessly integrate with rotary valves, screw feeders, vibratory dischargers, or airlocks.
- Abrasion & Corrosion Resistance: Critical areas, especially the lower cone and outlet, can be lined with abrasion-resistant steel (AR), stainless steel, or ceramic tiles to extend service life.
- Modular & Custom Designs: We build standalone hoppers, hopper modules for silos, and complex multi-outlet systems tailored to your plant layout.
Our Fabrication & Quality Assurance Protocol
Every project follows a stringent, documented pathway to ensure safety, compliance, and performance.
