Strainers of titanium grade 2, by a customer from the petrol and oil industry.
It concerns 25 3/4 ″ and 1″ strainers which are deployed on a PTA chemical plant.
The titanium strainers are welded in the purge chamber below 10 ppm, welding completely silver.
The slight discoloration outside the HAZ won’t hurt and is caused by cutting fluid residue which is included in the titanium oxide and because of the welding heat, it wants to burn.
