HARTLEPOOL, UK -- Corus Tubes has received an American Petroleum Institute (API) 5LD accreditation for the manufacture of corrosion resistant, clad pipeline at its Hartlepool, UK mill.
Clad pipe is made from plate with a stainless steel, corrosion resistant alloy layer, finished with a submerged arc weld (SAW). Corus Tubes says the product allows for recovery of previously unviable reserves in mature and sour service fields, which contain high levels of hydrogen sulphide and Carbon Dioxide.
The Monogram License allows Corus Tubes to use the Institute’s monogram, certifying the business as an accredited manufacturer inline with API’s manufacturing and quality assurance standards.
Corus Tubes has developed a process, using metallurgically bonded clad plate that is formed into linepipe using what is known as the UOE method, where the material is formed into a “U”, then an “O” shape, before being expanded to the final dimensions.
The company says this method enables faster production of large quantities of linepipe in the same dimensional and mechanical tolerances as offshore grade carbon steel material.
