Hot Dipped Galvanized Astm A36, Hot Dipped Galvanized A wide variety of hot dipped galvanized astm a36 options are available to you, such as jis, din, and aisi. You can also choose from a53(a,b), 10#, and q235. As well as from structure pipe, gas pipe, and ship plate. And whether hot dipped galvanized astm a36 is hot rolled, cold drawn, or cold rolled.
1.Higher Working Pressure Capbility: Under same working pressure, the stress to the sprial welding seam is 75%-90% of striaght seam, so the sprial pipe can bear higher working pressure. Therefore, the wall thickness of sprial pipes can be 10%-25% less than stright seam pipes under same working pressure, saving costs for the material;
2. Good Precision: the tolerance of diameter is usually with in 0.12%, the deflection is less than 1/2000, and ovality is less than 1%, so the sizing and strenghtening works can be saved;
3. High Utilization: the sprial pipes can be continually produced, with less loss of cutting head and end, which can rise the utilization of 6%-8%;
4. Full Range of Sizes: the sprial pipes are ranging from small diameter to large diameter, easier operation than straight seam pipe;
