What Are Structural Skid Bases?

A structural skid system is a steel frame foundation designed to support modular process equipment. These skid bases are engineered for heavy loads, vibration resistance, and precise alignment, providing a reliable platform for industrial process systems.

Key components and features include:

• Steel frame skid base – Fabricated to AWS D1.1 standards for maximum strength.
• Support mounts for equipment – Pressure vessels, pumps, and heat exchangers.
• Integration points – For piping, valves, instrumentation, and modular skids.
• Pre-fabricated & pre-tested – Factory assembly ensures operational readiness and quality compliance.

  

   

Provide Structural Skid Bases meeting following Codes

• AWS D1.1 for Structural Skids and Pipe Supports
• ABS, DNV for Offshore and FPSO
• Any other Code requirements requested by Customer specification

Quality & Safety in Structural Skid Base Fabrication

The AWS D1.1 code is the American Welding Society’s standard for structural steel fabrication. Skids built to this standard have:

• High structural integrity – Strong welded joints capable of supporting heavy industrial equipment.
• Compliance & safety – Certified welding ensures adherence to industry regulations.
• Durability & reliability – Skids withstand operational stresses, vibration, and environmental conditions.

PPV Corp welders are certified according to AWS D1.1 Code, and all fabrication follows qualified welding procedures (WPS/PQR).

Non Destructive Examination (NDE)

During Assembly, welding and fabrication process to check quality and integrity following NDE and testing techniques are used.

• Factory Acceptance Test (FAT)
• Visual Testing (VT)

• Full or Partial Radiography (RT, X-ray)

• Liquid Penetrant Testing (PT)

• Magnetic Partical Testing (MT)

• Ultrasonic Testing (UT)

• Positive Material Identification (PMI)

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
