Assembly of Modular Skid and Process Systems – PPV CORP

PPV CORP specializes in the assembly of modular skid systems, delivering fully integrated, factory-tested units that are ready for rapid deployment in industrial, chemical, oil & gas, and power applications. Our modular skid assembly process ensures that all equipment, piping, instrumentation, and structural supports are installed with precision, safety, and compliance with industry standards.

What Is Modular Skid Assembly?

Modular skid assembly is the process of integrating all process equipment and structural components onto a pre-fabricated skid base, resulting in a self-contained, turnkey unit. This assembly includes:

• Mounting pressure vessels, pumps, heat exchangers, and compressors onto the skid frame.
• Installing piping, valves, and instrumentation according to process schematics.
• Integrating electrical, control, and automation systems for operational readiness.
• Performing factory testing to verify pressure, leak integrity, and equipment functionality.

The result is a compact, transportable, and fully operational modular skid system that significantly reduces on-site installation time and labor costs.

Steps in Modular Skid Assembly

Structural Skid Preparation

• Fabricated structural skid base (AWS D1.1 certified or equivalent) is inspected and leveled.
• Skid base is prepared for mounting equipment, piping, and instruments.

Equipment Installation

• Mounting pressure vessels, pumps, heat exchangers, and other major components.
• Securing equipment to ensure proper alignment and vibration control.

Piping & Instrumentation Integration

• Pre-fabricated or custom piping is installed according to process design.
• Valves, gauges, sensors, and control instruments are installed and wired.

Electrical & Control Systems

• Power wiring, control panels, and automation systems are integrated.
• Safety interlocks, sensors, and monitoring devices are tested for functionality.

Testing & Quality Assurance

• Pressure tests, leak tests, and functional checks are performed.
• Compliance with ASME, API, or AWS D1.1 standards is verified.

Final Inspection & Certification

• Complete documentation including inspection reports, material certificates, and testing logs.
• Skid is packaged and prepared for transport to the site.

Common welding processes used at PPV CORP are:

• MIG Welding - Gas Metal Arc Welding (GMAW)

• TIG Welding - Gas Tungsten Arc Welding (GTAW)

• Flux Welding - Cored Arc Welding (FCAW)
• Submerged Arc Welding - Sub-Arc Welding (SAW)

MIG WELDING (GMAW)
MIG welding is one of the easier types of welding for beginners to learn. MIG welding is actually two different types of welding. The first uses bare wire and the second flux core.
Bare wire MIG welding can be used to join thin pieces of metal together. Flux core MIG welding can be used outdoors because it does not require a flow meter or gas supply. MIG welding is usually the welding of choice for DIY enthusiasts and hobby welders who don’t have the money to spend on expensive equipment.

STICK WELDING (SMAW)
Stick welding, also known as Arc welding, is doing it the old-fashioned way. Stick welding is a bit harder to master than MIG welding. Stick welding uses a stick electrode welding rod.

TIG WELDING (GTAW)
TIG welding is extremely versatile, but it is also one of the more difficult welding techniques to learn and are skilled individuals.
Two hands are needed for TIG welding. One hand feeds the rod whilst the other holds a TIG torch. This torch creates the heat and arc, which are used to weld most conventional metals, including aluminum, steel, nickel alloys, copper alloys, cobalt and titanium.

Submerged Arc Welding (SAW)
SAW welding is a high-productivity, automated process where an electric arc is submerged under a blanket of granular, fusible flux to join thick metal plates.
It offers superior penetration, high deposition rates, and no visible arc or spatter. Common uses include shipbuilding, pressure vessels, and heavy structural components
