FAQ

Q1: What is the main difference between "Clad" and "Lined" pipe?

A: It's all about the bond. Clad pipe has a metallurgical bond (the atoms are fused together), usually achieved through hot rolling. It is more expensive but handles high heat and vacuum better. Lined pipe has a mechanical bond (interference fit), achieved by expanding the inner pipe inside the outer. It is more cost-effective and suitable for most standard corrosive transport.

Q2: Why not just use a solid stainless steel or solid Inconel pipe?

A: Cost and mechanical properties. Solid nickel alloys are incredibly expensive and sometimes lack the high-yield strength required for long-distance, high-pressure pipelines. Bimetallic pipes give you the "best of both worlds"—the strength of carbon steel and the protection of an alloy.

Q3: How do you weld pipes in the field?

A: Field welding is a critical process. Typically, the pipe ends are "seal welded" or "overlay welded" at the factory. During onsite installation, the root pass is made using a welding wire that matches the CRA layer (e.g., Inconel 625 wire), followed by filler passes to complete the joint.

Q4: Can these pipes be pigged for cleaning?

A: Yes. Since the CRA layer provides a smooth internal surface, standard cleaning and inspection "pigs" can be used. For lined pipes, it is important to ensure the liner is properly locked at the ends to prevent movement during high-velocity pigging.

Q5: What standard must be followed for these pipes?

A: The most recognized global standard is API 5LD. This standard covers the materials, manufacturing, testing, and inspection of both clad and lined steel pipes for the oil and natural gas industries.
