It is a capital mistake to theorise before one has data. Insensibly one begins to twist facts to suit theories, instead of theories to suit facts. (Sherlock Holmes - A Scandal in Bohemia.)

and this pipe system is for cooling purpose ( steam turbine and boiler system @ power plant)
i want to replace the current elbow that is already have so much leak on it due to long period of working ( cooling tower water return pipe from condenser ),and everyday,we are using water from river nearby and the water TDS is more than 15,000 @ salt water. we also faced a leakage at the main underground pipe that is i will maybe solve it later after i finish changing the rusty elbows and yes,it will be a lot of cuttings and welding.
and i use measuring tape to measure the size,OD and ID...i also use a string method ( string lenght divided to 3.142 ),also use very big DIY compasses to measure it..and the result different not much..
426mm-430mm is more likely is the OD
any better way to measure the size?
