This certification is a necessary demand of the market in which we work and demonstrates the trust of buyers not only in Europe, but in the whole world.” Interpipe is also building an electric arc furnace at Interpipe Steel (Dnepr steel) with a capacity 1.3 million tons of steel per year. The company’s products are in compliance with API 5L PSL1/PSL2, API 5CT, ASTM, EN (DIN), NF, , AAR, UIC, and European norms. The quality management system is in compliance with ISO 9001, ISO 14001, API Spec Q1 and ISO 9001. The company’s mills are located in the Dnepropetrovsk region of Ukraine.

To punch free of deformations with the through-punching method, the upper tube wall is cut by the punching die. Afterwards, the slug serves as the punching die’s extension and punches the lower tube wall. The punching slug becomes a cutting tool. The slug guide in the expansion die and the die holder has to be very tight so the slug cannot loosen. Using expanding mandrels, which are driven separately and have exchangeable dies, the tube can be punched free of burrs without further post- production. Petig machines allow the manufacturing of tubes up to 10m length, diameter up to 100mm and a wall thickness of 0.5 to 10mm. The disposal of the punching slugs is easy, because they fall through the machine table into a box after each punch. Depending on the tube size, up to four tubes can be processed simultaneously.

When the punching holes are in visible areas, deformations should be avoided. In order that the quality of the upper and lower perforations is virtually equal, the responsible expanding die is of great importance. Petig’s punching method with the expansion die has been successful for several years and finds application in many industries. Compared to single-sided punching, the company claims an increase of productivity of up to 35%. Without further working steps, tubes can be turned for further processing and thanks to the control system, the collet chucks in the feed can be rotated into any tube position. This way, the tube can be processed on different axes.

polishing and de-burring – Aluchem, Carbochem, Cuprochem, Tichem, Zirchem, Poligrat E; chemical colouring and anodising – Polispectral, Titancolor; coating – Poliant, Poliseal. Product groups for functional surfaces are: fouling/coating behaviour/ biocompatibility; fatigue resistance; emission behaviour; high frequency conductivity; corrosion resistance; solderability and weldability; metallic cleanness; passivity/ product neutrality; reflective behaviour/ cleaning behaviour; sterile properties; and vacuum behaviour/abrasion. Decorative surfaces: colour; smoothness; and cleaning behaviour/structure. Burr-free surfaces: smooth edges/burr-free; particle-free; crack detection; and sharpness/scale-free. A wide variety of materials can be treated, ranging from aluminium to zinc, with the emphasis on the treatment of stainless steel, mild steel, titanium and non-ferrous metals. Before and after: weld of a stainless steel sheet, cleaned and passivated with Polinox-Protect to improve corrosion resistance
