Seamless Steel Pipe
EN 10216 Steel Tube
EN 10216 seamless steel pipe is considered for pressure purposes. This feature of the stainless steel seamless pipe is essential because this type of pipes is constantly put to use where extreme conditions prevail and where safety of people and the trouble-free operation of plant and equipment must be ensured. our seamless stainless steel pipes are made to withstand the greatest heat and the highest pressure; they are unaffected by acids and don't give corrosion a chance! a seamless stainless steel pipe or tube can pass through more than 100 production steps before taking its final form and quality.
