GNEE is a manufacturer of high quality EN 10305-1/2/3/4/5 standard steel pipes. EN 10305 features precisely defined dimensional tolerances and specified surface roughness. EN 10305-1 seamless steel pipe is the European standard for cold drawn precision steel pipes.
EN 10305 Seamless precision steel pipes should be manufactured by cold-dipping hot-processed seamless pipes. Other suitable cold working methods are allowed and the pipe shall be delivered in delivery condition +N.
