I recently completed a close out contract, I ordered extra fittings for the increased volume of works, the Service Company sent fittings that had been put through such a machine, the surface of the fitting had be refurbished, oiled and re painted, But the refurbishment was only cosmetic, the nuts were still rounded, the bolt threads were stretched, burst and in poor condition, the gates were distorted, approx only 1 in 3 was serviceable, so the moral of the story is you only get out what you put in, you cant make a silk purse out of a pigs ear, dont expect new for old.
