tube manufacture Incoloy and stainless steel tube is manufactured from flat strip. It is a continuous process where the strip is formed into tube by a series of roll formers, welded, tested for defects, then cut to length. This length is determined from the customer's element profile requirements. Copper tube is purchased in level wound coils, straightened and cut to the required length. Copper, incoloy and stainless steel tube can then be offered to customers in this form. privacy | disclaimer     © , Hermetic New Zealand. All Rights Reserved.   A Nice site.
