Surface-treatment sandblasting Nozzles single entrance Type
surface-treatment sandblasting systems Nozzles
High temperature resistance, Abrasion-resistance, light unit weight, working life much longer than tradition material.
Application:
· Marine engineering— pre-painting surface treatment;
· Engineering — cleaning/deburring of castings and welded parts;
· Oil and gas pipeline treatment prior to application of protective painting layer
