Things Site Engineers Must Know About Reinforcement and

Longitudinal reinforcement should not be less than 0.8% and more than 6% of gross C/S.Weight of rod per meter length = d 2 /162 where d is the diameter in mm All reinforcement shall be free from mill scales,loose rust coats of paints,oil or any other substances.Tanks Wiggin Means PrecastA properly designed tank must be able to withstand the applied loads without cracks that could cause leakage.The goal of designing and constructing a structurally sound tank that will not leak is achieved by providing the proper amount and distribution of reinforcement,the proper spacing and detailing of construction joints,and the use of Tank Heads - Tank Components Paul Mueller CompanyTank heads are a critical piece of your tank fabrication,whether it's ASME flanged and dished,2:1 elliptical,standard flanged and dished only,or any other style.Paul Mueller Company can provide a wide range of custom tank heads with custom polishing,beveling,inspection,heat transfer,and other options.
