please provide me some stage checks to ensure staightness. There are many practical difficulties in maintaining the straightness . The reasons are 1. There is some amount of face out 2. Root welding is given priority while fitup. A uniform root gap of 2-2.5 is maintained. So the small amount...

I am incharge of header Manufacturing. From Fitup stage the straightness is lost. While welding the nipple/tubes to the body pipe , again bow(what we call for the bend in the body pipe) is induced. In PWHT , in furnace , while cooling the nipple/tubes act as heat transfer fins and again bow is...

After joining 2-3 pipes with butt joint, straighness of the centre line is deviated due to the thermal stresses and fitup face out. To bring back the component to a straight pipe, mechanical pressing is done using hydralic press, supporting the component as a simply supported beam and the load...
