iron, titanium, duplex), whereas the inner tube could be a high-corrosion- resistant alloy (copper, aluminium-brass, zirconium).

Be Ca Engineering Soc Coop is a manufacturer specialising in bimetallic tubes and hydrostatic and pneumatic testing systems for straight or bent tubes and pipes. Heat exchangers are stressed devices, for example when installed in power and nuclear plants, in fertilisation and urea treatment systems, or in chemical and petrochemical industry, above all due to the high working pressure, temperature and corrosive atmosphere. Strength and protection against corrosion are the main technical specifications for tubes used in heat exchangers. For this purpose Be Ca Engineering offers bimetallic tubes. The patented technology creates a unique bimetallic tube, starting from two distinct tubes with different materials. For example, if the corrosive atmosphere is due to the fluid located inside the tube, the outer tube could be a high- stress-resistant alloy (stainless steel, WHEN a US tube manufacturer repeatedly experienced premature corrosion on pipes, end-user warranty claims and unanswered service requests to their coatings supplier, management realised it needed serious help from industry experts. They took action and contacted Quaker Chemical Corporation. Quaker is a global provider of process chemicals, services and technical expertise to a wide range of industries. It offers a complete “front-to-back” product portfolio for the tube & pipe industry, including lubricants, coolants, cleaners, rust preventives and coatings – including UV coatings. Quaker used its integrated knowledge of steel manufacturing, metalworking fluid processes and coatings chemistry to recommend an appropriate solution that would not only increase the flexibility of the tube coating, but also

Bimetallic tubes offer a technical and economical solution for the production

Bimetallic tubes from Be Ca Engineering

Flexible UV coatings help to build business

offer superior corrosion protection and increase the cosmetic appearance of finished tubes. The resulting elimination of rejects/returns and improved quality not only decreased costs, but also opened new sales opportunities for the manufacturer. Quaker’s customised QUAKERCOAT ® product is a high- gloss, 100% UV-curable, permanent protective coating. This product offers a lower total applied cost, because the formulation chemistry provides balanced properties for flexibility, hardness and corrosion protection. In addition, this eco-friendly line contains zero-VOC emissions and has virtually no overspray and very limited discharge. Quaker’s QUAKERCOAT ® UV product, the tube manufacturer was able to: eliminate the premature corrosion issues, which resulted in significant cost By switching to

savings ($85,000 saved in lost claims and $25,000 saved in rework over an 8-month period); receive regular technical service visits from Quaker, resulting in increased worker morale because the operations staff felt taken care of by their management team; and increase its own market image and as a result gain new business. Quaker Chemical Corporation is a leading global provider of process chemicals, chemical specialities, services, and technical expertise to a wide range of industries – including steel, aluminium, automotive, mining, aerospace, tube and pipe, coatings and construction materials. Quaker’s products, technical solutions, and chemical management services enhance customers’ processes, improve product quality, and lower costs.
