Steel and tungsten carbide rolls for tube forming and straightening

Eurolls Spa is a leading provider of wire and tube processing equipment. With thirty years of experience, technical knowledge, a choice of high-quality materials, and a highly specialized team, the Italy-based company is the reference point for many manufacturing sectors, including the automotive, furniture, electrical, and oil industries.

Among the wide range of products developed by the company, we find steel and tungsten carbide rolls for forming and straightening of welded tubes. The choice of the material is determined by various factors, such as the material of the tube (cold-rolled steel, galvanized steel, stainless steel, Incoloy, aluminum, titanium, copper, and its alloys), the welding method, the milling speed, and the productivity and quality of the final product required. It is important to emphasize that Eurolls forming rolls are suitable for all existing welding methods, such as high frequency, TIG, and laser.

Forming rolls for welded tubes

Regarding the manufacturing process of Eurolls-branded forming rolls for welded tubes, they are salt-bath hardened in 2 or 3 hardening processes and then ground and polished on the surface, ensuring superior performance and further increased durability. Each product is accompanied by a test certificate and construction drawing (for rolls designed directly by Eurolls) . The products are also made to international standards (DIN - ASTM - API - JIS, etc.). The Italy-based company manufactures in particular:

• large rolls with diameters up to 28" in round, square, or rectangular shapes, ideal for the production of large pipelines for the transportation of oil and gas;
• rolls with floating flanges (on bearings or grease film), capable of producing a finished product with a lower risk of defects. They are therefore ideal for processing stainless steel tubes;
• accessories for tube forming lines, such as cutting and welding vises, spacers, and accumulator rolls.

Straightening rolls for welded tubes

During the various production processes, tubes may undergo bending and deformation: to ensure a final product is perfectly in line with the required dimensional and structural specifications, it is necessary to perform a straightening process. Straightening rolls can be made of steel or tungsten carbide and vary in both design and configuration, depending on the size and type of tube to be straightened.

In the case of high-quality products, such as automotive or furniture applications, and whenever the production of a tube with tight tolerances is required, Eurolls offers its customers solutions involving combined materials, including carbide rolls for the most critical applications or where rolls are subject to wear. Eurolls will recommend the solution that offers the most technical advantages in relation to its price.
