What is minimum pressure gauge for GI testing?

Minimum pressure gauge for galvanized iron testing :

• Minimum yield strength of finished top tube should be 50000 psi
• Minimum tensile strength for the finished tube shall be 55000 psi
• The mechanical property of the finished surface of the cube is mainly depended upon the tube size and gauge.
• Generally galvanized iron pipes are used for the distribution of treated as well as raw water in rural and urban areas
• Such type of pipes are very cheaper and its weight is very very light so that it can handle anywhere.
• The tensile strength of galvanized iron pipe shall be at least 320 Newton per mm square.
• The test shall be carried out on full section cut from the selected tubes in accordance with IS1608 and IS 12278
