Acid pickling tank offers extreme corrosion resistance

fusion welding, hot gas extrusion welding technology and hydro-thermo radius forming technology. In addition to butt fusion technology, Anticor has developed radius instead of a right angle corner at the bottom of tank. This effectively reduces the weld joint at the welded corner radius, thus providing sound mechanical strength. Anticor weld joints are tested as per German Welding Association DVS 2203. The company’s tank fabrication technology offers better performance, higher efficiency, higher productivity, lower rejection, zero failure and an environmentally friendly atmosphere. Welding quality is confirmed by a 3-point bend test, and a specimen seam is subjected to a test of tensile and impact resistance properties. Leak testing is carried out prior to dispatch by hydro, vacuum and spark test. Anticor pickling tanks are supplied with accessories such as nozzles, heating/ cooling coils, integral suction ducting for fume exhaust, integral slope for drain, lifting Over the planning stages a number of unforeseen problems occurred, which Wheelabrator and Duraloy worked together to resolve. The problems were identified and a new machine designed which was quickly and efficiently produced in a very short time. Making this design even tougher, Wheelabrator worked within the limited space requirements and designed the skew roll blasting machine to fit in with the existing manufacturing facility. “We’ve been extremely pleased with the new skew roll machine. It’s two wheels cut our run time in half and added much needed flexibility,” said Mr Paul Rokosz, Duraloy vice-president and general manager. Wheelabrator Group, a global provider of surface preparation and finishing solutions, celebrates its 100 th anniversary in 2008. The company is committed to offering the broadest array of technologies, products, services and technical know-how.

Arvind Anticor Limited, India, is a manufacturer and exporter of acid pickling tanks made from extremely corrosion resistant polypropylene thermoplastic. The company’s acid pickling tanks are custom designed according to size and weight of load such as tube, pipe, wire coils, bars, rods and structural steel. Anticor PP tanks are used for pickling, degreasing, electro-plating, rinsing, fluxing, anodising, passivation, pre- and post- treatment and metal surface treatment.

conventional alternatives such as brick lining and fibreglass lining. Benefits include cost saving, impact resistance, corrosion resistance, mobility, minimal weight, leak- proofing, environmental efficiency, fume free, increased longevity and zero maintenance. Anticor tanks are designed, manufactured and tested according to German Welding Association DVS 2205 for safety and longevity. The tanks are manufactured with certified life of chemical resistance. Anticor’s facilities are equipped with butt

The tank is constructed from polypropylene thermoplastic – a material that is highly corrosion resistant. In addition, the tank is housed in a steel structure frame for mechanical reinforcement, covered with fibreglass. The tanks are designed and engineered on the ‘Rita’ tank building software module. All areas of design, calculation, costing and calculating PP tanks are geared towards maximising the benefits of advanced material over

Roll blasting machine for removal of tenacious coatings

Wheelabrator Group, Canada, recently installed a new, unique two-wheel skew roll blasting machine at Duraloy which is essential in removing the chalky, tenacious, refractory coating from the tubes produced during the centrifugal casting process.  The two-wheel skew roll blasting machine from Wheelabrator

This unique blasting process is followed by a Zyglo inspection that ensures that the chalky, refractory residue is completely removed, so that the tubes can be checked for defects that could be formed during the casting process. Duraloy Technologies Inc is a manufacturer of centrifugal and static cast components and assemblies for various industries, including steel mill and steel processing, petrochemical, fertilizer, refining and chemical heat-treatment. Utilizing ISO 9001:2000 and European PED registered quality assurance systems, Duraloy remains a technology leader in engineering and design. The Wheelabrator ® machine accommodates a variety of casting sizes, from 3″ to 20″ in diameter. Since the installation of the new Wheelabrator machine, Duraloy has decreased cycle times, saved money and eliminated the production bottlenecks associated with the former blaster.
