API675 API675 khansaab (Mechanical) (OP) 28 May 15 18:52 Hi All, Can anyone please help me and explain what is API675 and according to it what should be considered in selecting a dosing pump for chemical injection package. RE: API675 micalbrch (Mechanical) 1 Jun 15 08:02 The standard has 69 pages. How should anyone summarize 69 pages in a few sentences? Do you have the sandard? Are there specific questions? That would make it easier to help you.
