Second line for SAW spirally welded steel pipe production

technical partner Byard Spiral Mill, one of the main suppliers of equipment for SAW spirally welded steel pipe production. Hannibal Pipes SA is active in the manufacture of SAW spirally welded steel pipes for water, oil and gas, solar, piling, infrastructure applications with diameters between 219 and 2,540mm (8" and 100") and thickness up to 25mm. Located in the south of Spain, in an area directly connected through railway with Cartagena Port, Hannibal Pipes also designs and manufactures a large range of steel special pieces, including bends, T connections, sleeves and couplings.

Spain is a leader in CSP technology, with more than 50 projects approved by the government, and it exports its technology. The country added 400MW in 2010, taking the global CSP lead with a total of 632MW, and as of April 2011, another 946MW of capacity was under construction with a total new capacity of 1,789MW expected to be in operation by the end of 2013. SAW spirally welded centre pipes are a key element in CSP technology due to stringent requirements/parameters in terms of roundness and parallelism tolerance and for subsequent treatments received by pipes before final installation. The new line purchased by Hannibal Pipes allows high precision and was designed to meet such demanding specifications in cooperation with

Hannibal Pipes SA, which started operation last May in the south of Spain, has entered into the second phase of its investment, with the installation of a new production line for manufacturing small/medium diameter SAW spirally welded steel pipes. The line, with production range from 219 to 609mm (8" to 24"), will mainly supply pipes serving as centre pipes for concentrated solar power (CSP) projects. Hannibal Pipes is already carrying out several projects supplying more than 100km of SAW spirally welded centre pipes for CSP investments within the Iberian Peninsula. The new production line was expected to start production by January 2012, adding around 20,000 tonnes/year to the existing installed capacity of 90,000 tonnes/year.

Press-Fit valve range Leading manufacturer Hattersley has launched a new range of dedicated Press-Fit valves featuring integrated Geberit Mapress adaptors, offering building services engineers a variety of time and cost-saving benefits, as well as excellent quality and reliability.

for pre-fabrication, thanks to the accuracy that can be achieved – pipes can be pre-cut, safe in the knowledge that the exact dimensions and tolerances are known in advance and can be relied upon. Mapress Press-Fit technology makes installation faster and cleaner, without the health and safety risk factors of soldering and threading, and is increasingly being recognised for its reliability and added value. Both the valves and adaptors have been specifically designed with parallel threads to ensure an enhanced thread engagement and thus a superior resistance to bending forces, and much greater reliability. In fact, Hattersley’s rigorous bend and vibration testing (to EN331 and DVGW respectively) has revealed that its new valves are more stable than some similar Press-Fit valve units.

Comprising a ball, balancing, strainer and check valve, the new Press-Fit valve range is suitable for use with both copper * and Geberit Mapress Stainless and Carbon Steel tubing. The range is made to the same high specification as Hattersley’s trusted project valves, but with the additional benefits of integratedGeberit Mapress adaptors. By supplying the valve and adaptors assembled and tested as one unit, the number of purchased components and joints required on site can be halved. This not only simplifies the purchasing process, keeps costs down and significantly lowers the installation time, it also reduces the risk of a leak. The Press- Fit valve range is particularly suitable
