The Development of Corrosion-Resistant Tubing

Abstract

Corrosion problems of deep well tubings and their control measures are discussed. As one of the economical solutions, metal-lined tubings·are proposed. It is shown that the metal liner can be tightly fitted by the newly developed thermo-hydraulic fit method. The selection of corrosion-resistant material for the liner is discussed. Some designs of the tubing joint and their manufacturing methods pre proposed.

Analysis of Process Parameters for Different Material Pairs of Mechanically Lined CRA Pipes Manufactured by Thermal-Hydraulic Expansion Process

“…Mechanically lined CRA pipes can be manufactured using two different methods: hydraulic and thermalhydraulic expansion processes [10]. In the hydraulic expansion manufacturing process, internal pressure is applied to the liner pipe after its insertion into the outer pipe.…”

Corrosion Performance of Welded CRA-Lined Pipes for Flowlines

“…Therefore, several manufacturers are producing a steel pipe with only a CRA lining as a cost-effective alternative to solid pipes. [1][2][3] The double-wall, bimetallic CRA-lined pipe has an inner layer made of a very resistant CRA and an outer layer made of low-cost steel. Some CRA-lined pipes have metallurgical bonding between the lining and the steel,I,2 while some have only a mechanical bond between the CRA layer and the steel layer.…”

“…Some CRA-lined pipes have metallurgical bonding between the lining and the steel,I,2 while some have only a mechanical bond between the CRA layer and the steel layer. 3 The metallurgically bonded pipes (called clad pipes) usually are manufactured by such processes as coextrusion, hot-rolled bonding, explosive Tensile Strength. Yield and tensile strengths of the steel layer were measured after cladding removal.…”
