Stainless steel pipes for offshore oil and gas industries

Any fault can lead to loss of energy, high repair costs and, in the worst case, environmental damage. At OTC Schoeller Werk will demonstrate how these challenges can be met. The company is a manufacturer of stainless steel piping with 35 years of experience in the offshore industry. At the conference, the focus will be on chemical injection and control line piping. These deal with pumping chemicals into an oil reservoir or act as hydraulic control pipes for safety valves. Schoeller Werk uses a wide range of austenitic stainless steels and nickel- based alloys as well as a special manufacturing process to finalise the pipes. They are first welded using the tungsten inert gas (TIG) technique, then subjected to a drawing process to reduce the pipe walls to the required thickness. The company states that this results in superior surface quality and better quality of the welded seam. Even at a microstructural level, the weld is hardly noticeable.

At the Offshore Technology Conference (OTC) in Houston, Texas, USA, Schoeller Werk will exhibit its solutions for the extraction of oil and gas on the high seas, which are tailored to industry requirements. At stand 3615-3 in Hall B the company, which specialises in German-made longitudinal seam-welded piping, will demonstrate its heavy-duty control line and chemical injection pipe solutions, which are precision-designed for use at a depth of 10,000m below surface level. The surface quality of the pipes and the quality of the welded seam allow the pipes to withstand extreme conditions. For customers in the offshore industry, the array of products is enhanced by a broad range of services, including encapsulation, and flushing and filling of pipes. The requirements for piping in the offshore industries are demanding: extreme pressure, temperatures up to 300°C, aggressive media and salt water.

If required, the company can supply solutions with an external diameter of 3.18 to 25.4mm; the wall can range from 0.5 to 2.11mm in thickness. Depending on the specifications, the pipes can be suitable for pressures as high as 2,500 bar. It is also possible for customer- specific requirements to be supplied, if found to be feasible after assessment. Schoeller Werk supplements this range of products with services to deliver an overall concept for the offshore industry. These services include encapsulation of pipes with plastic sheathing in flat-pack format, and flushing and filling of pipes. The company can also equip pipe bundles with TEC and PDC cables or stainless steel bumper wires. The smooth pipes are also suitable for installation of fibre optics.
