Pipe Cladding Machines

SOMO manufactures hydroforming pipe cladding machines ideal to clad an outer carbon steel pipe with an inner stainless steel pipe (Inconel).

In the pipe cladding process, corrosion of tubular products is a typical problem due to acidic working environments. In these settings, bimetallic piping (BP), consisting of a low-carbon steel base layer and a corrosion-resistant alloy (CRA) liner layer, is an affordable and reliable anti-corrosion technology.

Using a pressure of 1,000 bar, the hydroforming pipe cladding machine allows the two tubes (outer tube + inner liner) to be deformed to make them bond together.

Applications of pipe cladding process

The pipe cladding process plays a vital role in industries where corrosion resistance, mechanical strength, and thermal protection are essential.

Common applications:

• Oil & Gas: internal and external cladding of pipelines to resist corrosive substances and pressure fatigue.
• Chemical Processing: protecting pipe interiors against aggressive chemicals and high temperatures.
• Power Generation: enhancing the durability of pipes in boilers, turbines, and heat exchangers.
• Marine Industry: shielding pipelines from seawater corrosion in offshore platforms and ships.
• Water Treatment: cladding for stainless steel piping systems in desalination or purification plants.
  
  

SOMO’s pipe cladding machines are engineered to support high-precision overlay welding and automatic cladding in these demanding fields. The process ensures long-term performance of base pipes with minimal maintenance.

FAQs

1. What is pipe cladding?

Pipe cladding is the process of applying a protective layer—often using corrosion-resistant alloys (CRA)—onto the surface of a base metal pipe. The goal is to combine the mechanical strength of the base pipe with the chemical resistance of the cladding layer.

This pipe cladding process enhances durability and significantly reduces the need for full exotic alloy construction, lowering material costs.

2. What are the parts of pipe cladding machines?

A typical pipe cladding machine includes:

• Cladding head: carries the welding torch or deposition tool
• Rotating system: ensures the pipe is uniformly processed
• Control system: often CNC-controlled for precision
• Wire feeder: supplies filler material during cladding
• Cooling units and shielding gas systems, depending on the application

SOMO machines are customisable and designed to integrate seamlessly into automated production lines.

3. What is pipe insulation?

Pipe insulation is a different process where insulating materials are applied to pipes to retain heat, prevent freezing, or improve energy efficiency. Materials commonly used include fiberglass, mineral wool, and polyurethane foam.

4. What are the Differences Between Pipe Insulation and Pipe Cladding?

While both processes protect pipes, cladding is structural and anti-corrosive, while insulation is thermal and energy-saving.

5. What is the CRA cladding process?

CRA cladding (Corrosion Resistant Alloy) is a subtype of the pipe cladding process in which a high-alloy material such as Inconel, Hastelloy, or Duplex Stainless Steel is bonded to a lower-cost base metal like carbon steel.

This process enables:

• Enhanced chemical resistance
• Resistance to abrasion, pressure, and high temperatures
• Extended service life in critical applications
  
  

CRA cladding is often performed using GMAW, GTAW, or SAW processes, and SOMO’s machines are fully compatible with these techniques.
