Re: [MW:7701] DIFFERENCE BETWEEN PIPE AND TUBE

Hi, The normal difference between pipe and tube is how the size is designated. PIPE - is designated by a "Nominal Pipe Size (NPS)" based upon the ID (inside diameter) of the most common wall thickness (Schedule). Pipe is used to stop the heat transfer (i.e send steam thru pipes) in boiler applications. Tube - is designated by the measured OD (outside diameter). Tube is used when we need to transfer heat from its walls in boiler applications.   For Example: 3/4"pipe has an OD of 1.05", while a 3/4"steel tube has an OD of 0.75".   Thanks & Regards,   (karthik) Karthikeyan.S QA/QC Manager Getabec Energy Co.,Ltd. 379,Moo6,Soi8,Nikhomphatana, Rayong-21180, Thailand.
