New High Power Infrared Emitters Help To Produce Innovative Pipelines

QRC® Infrared Emitters with Nano Reflectors for New Technology
  • Infrared emitters transfer heat without contact
  • New QRC® emitters with nano reflectors improve automated heating processes
  • Infrared emitters from Heraeus Noblelight help to manufacture pipe at point of use, allowing faster installation, shorter project lead times and higher pressure ratings

High power infrared emitters from Heraeus Noblelight, fitted with newly developed opaque quartz reflectors, are helping to ensure the bonding of a high-tech polypropylene composite coating on pipeline manufactured using an innovative pipeline construction technology. The custom-built shortwave infrared system is pyrometer controlled to ±3ºC and is moved around the pipe to allow the infrared heaters to be located as close as possible to the pipe surface.

Traditionally, pipeline for the oil and gas sector is manufactured in lengths of 40 ft (12m), with typical wall thickness around 15mm. Completed pipelengths are next sent to pipe coating yards and then transported to site where they are butt-welded together.

The new pipeline construction technology, X200, from Pipestream Inc, a portfolio company of Shell Technology Ventures Fund 1, relies on using a thin-walled pipe for fluid containment, with the pipe’s hoop strength being conferred by strips of martensitic steel which are helically wound around the thin-walled pipe, at diameters up to 24 inch. The assembly is then coated with a suitable coating material, such as polyolefin tape. Pipe manufacture, including coating, is a continuous process producing continuous pipe lengths in excess of 450m. The individual manufacturing stages are fitted within standard ISO containers, so that pipe manufacture can be carried out at point of use, allowing faster installation, shorter project lead times and higher pressure ratings. To date 6 inch diameter pipes having been manufactured subjected to pressure, bursting at 300 bar.

The manufacturing process is a three-stage one. First stainless steel is formed and welded to create the inner liner. The martensitic steel strip is then helically wound on and fixed to the liner by an adhesive. Formerly, this adhesive was cured using high power infrared but latest versions of the technology use an adhesive which cures at ambient temperatures. Finally, a polyolefin tape is helically applied, both for insulation and for corrosion protection. This is bonded to the pipe by an adhesive, and the high power infrared heaters are used to heat the pipe before the coating tape with its adhesive is applied. As the coating tape is a thermal insulator, it is not possible to cure the adhesive through the coating. However, one pair of heaters heats the tape itself to maintain flexibility. There are three pairs of high power short wave heaters arranged around the pipe circumference. These are rotated to match the winding speed and they are zone-controlled by pyrometers to provide hold temperatures to ±3ºC to ensure adhesive curing and to avoid bubbling or over-softening of the coating tape.

The newly developed QRC® infrared emitters used in this application provide high energy short wave radiation rapidly and responsively. Their new quartz reflective coating has a special nano- and micro-structure which provide the reflector with very high diffusion characteristics to ensure the stability of process parameters, such as temperature and coating homogeneity. The emitters operate at around 2000ºC with a power density of 300 kW/m2, enabling them to provide very large amounts of heat rapidly and efficiently to exactly the point of use.

Heraeus Noblelight GmbH with its headquarters in Hanau and with subsidiaries in the USA, Great Britain, France, China, Australia and Puerto Rico, is one of the technology and market leaders in the production of speciality light sources. In 2008, Heraeus Noblelight had an annual turnover of 92.5 Million € and employed 735 people worldwide. The organisation develops, manufactures and markets infrared and ultraviolet emitters for applications in industrial manufacture, environmental protection, medicine and cosmetics, research, development and analytical laboratories.

Heraeus, the precious metals and technology group headquartered in Hanau, Germany, is a global, private company with over 155 years of tradition. Our businesses include precious metals, sensors, dental and medical products, quartz glass, and specialty lighting sources. With product revenues approaching € 3 billion and precious metal trading revenues of € 13 billion, as well as over 13,000 employees in more than 110 companies worldwide, Heraeus holds a leading position in its global markets.

Im Focus: Can the immune system be boosted against Staphylococcus aureus by delivery of messenger RNA?

Staphylococcus aureus is a feared pathogen (MRSA, multi-resistant S. aureus) due to frequent resistances against many antibiotics, especially in hospital infections. Researchers at the Paul-Ehrlich-Institut have identified immunological processes that prevent a successful immune response directed against the pathogenic agent. The delivery of bacterial proteins with RNA adjuvant or messenger RNA (mRNA) into immune cells allows the re-direction of the immune response towards an active defense against S. aureus. This could be of significant importance for the development of an effective vaccine. PLOS Pathogens has published these research results online on 25 May 2017.

Staphylococcus aureus (S. aureus) is a bacterium that colonizes by far more than half of the skin and the mucosa of adults, usually without causing infections....

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.

We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...

Im Focus: Wafer-thin Magnetic Materials Developed for Future Quantum Technologies

Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.

Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...
