The clad pipe includes an external layer and a coating layer made of Ni base anticorrosion alloy. Both end portion areas of the coating layer are formed by a build-up welded layer (Ni base alloy of composition 1) on the inner surface of the external layer. Other areas are formed by a Ni base alloy layer (Ni base alloy of composition 2) fusion-bonded to the build-up welded layers and the inner surface of the pipe, a solidus-curve temperature of the Ni base alloy layer being 1300° C. or below and lower than a solidus-curve temperature of the Ni base alloy formed by build-up welding by 150° C. or more. Composition 1 and composition 2 are adjusted so that, in the same environment, corrosion resistance of the Ni base alloy of composition 1 is equivalent to or superior to that of the Ni base alloy of composition 2.

Nondestructive tests (NDTs) are performed in compliance with API 6A, API 5LD, and DNV OS F101 standards, or as otherwise specified by the client.

Economic Use
The Clad/Lined Pipe can be equally allocated the pressure to outer pipe and the corrosion-resisting to inner pipe. The material combinations dramatically reduce the cost of raw materials, and the average cost is just 1/6~1/3 of CRA. Furthermore, the cost effectiveness increases as the length of the pipeline increases due to reduced installation and welding expenses.

Safety
The Clad/Lined Pipe, selecting more suitable CRA material as its inner pipe based on the corrosion environment, totally owns the corrosion-resisting property of CRA. Comparing with inhibiter, this solution avoids the risk caused by the complicated management process and guarantees the operating safety.

Innovative Technology
Underwater deflagrating and cladding technology is the instant forming technique that makes the inner pipe be telescopically aligned inside the outer pipe through internal expansion of detonation wave, and it results in a tighter bond between the two pipes. This technology keeps the stability of physical and chemical properties for outer and inner pipes during the cladding process.

Corrosive Resistant Lining: Clad Pipe - Clad Tubes - Clad Lined I.D. - Clad Surface O.D.explosion bonded tubes and pipes. With Explosion Bonding technology we manufactures explosion bonded clad tubes and pipe with a true "metallurgical bond". The clad metal surface can be explosion bonded to the I.D. or O.D. providing the most robust corrosion and erosion resistance for tubes and pipes. Explosive Bonded Clad Tubes and Explosive Bonded Clad Pipes now provide options for the design engineers focused on providing solutions for the most demanding opportunities in the chemical processing, energy / power, and petro-chemical Industries.

Clad Tube Sheet Material
Explosion Bonded - Corrosive Resistant CLAD Lining (Provides a Metallurgical Bond)

The most common application of explosively bonded (clad) metals, is as corrosive or erosive resistant linings of pressure vessels, chemical process tanks, heat exchangers, and tube sheets. Not only do valued customers benefit from the corrosive resistance clad, but also from significant cost reduction by being afforded the opportunity to utilize structural steels to improve wall strength without having to manufacture the entire structure out of the, typically expensive, corrosive resistant materials.

Nickel Tube Sheets- Explosion Bonded / Alloy Tube Sheets- Explosion Bonded / Explosion Bonded Clad Tube Sheets by PA & E

Another application of metallurgically bonded clad pipes made of roll-bonded clad plates are so-called catenary risers in the offshore industry. These vertical pipelines connect the subsea gas or oil field with the production facilities above sea level. Due to the high pressure of deep water installations and dynamic loads by waves and drifts as well as due to the corrosive medium inside such riser pipes must provide excellent mechanical properties as high strength combined with good toughness as well as proper corrosion protection.
