astm a36 q235 hot dipped carbon

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.

Advantages:
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;
