Surface and shape of pipe fittings
Thread Content
Is it necessary to sandblast the surface of pipe fittings? Isn’t the shape of the large and small heads an acceptable shape according to the standards? Is it a problem to mark the elbows side by side on the outer arc? I hope the expert can give some advice
Regarding sandblasting, is it aimed at polishing storage surfaces? I wonder, is it necessary to sandblast the surface of pipe fittings? ”Is there any other meaning as well? Please make it clear.
Stainless steel pipe fittings are used in pipelines, and those that are not sandblasted are common; when one sees ones that have been sandblasted, it can be a bit confusing
Surface sandblasting is done to remove rust and as a base for spraying; stainless steel can also be used. In most cases, elbows are sprayed on their curved surfaces at the time of manufacture
Sandblasting is a process used to remove oxide scales and rust from the surface of pipe fittings; it is one of the steps in the manufacturing process. There are sandblasted surfaces (which appear dull); sandblasting can be done using fine or coarse sand, and the resulting appearance varies accordingly. There are also metal shot-blasted surfaces (shiny).
Some pipe fittings do not have their surfaces treated with sandblasting. Since sandblasting is part of the manufacturing process, do such fittings considered defective products? Can they be used? I would also appreciate some guidance from the experts
