General stainless steel tank internal steel welding requirements
General stainless steel tank internal steel welding should comply with what provisions? As long as you know these, welding can improve the success rate of welding.
1, cold-drawn steel should be welded joints, and then cold-drawn;
2, cold drawn low carbon steel wire, shall not use flash butt welding and arc welding;
3, welded joints from the bending of the bar, should not be less than 10 times the diameter of steel;
High pressed galvanized drinking water storage tank
4, the axis of tension and small eccentric tension in the steel members, should be welded;
5, directly under the heavy work of the crane components of the force in the reinforcement, should not use welded joints;
6, set in the same components within the welding joints should be staggered from each other. In the range of 30 times the diameter of the reinforced steel bars (not less than 500mm, see Figure 1), a steel bar shall not have two joints (the full length of the reinforcement shall be made of at least a welded joint), and the cross- Percentage of total cross-sectional area of steel bars, non-prestressed steel bars: tension zones should not exceed 50%; pressure and assembly structures are not restricted.
Hot-dipped Galvanzied Sectional Water Storage Tanks for Water Treatment
Pre-stressed steel: tension zone should not exceed 25%; when using flash butt welding, reliable quality can be relaxed to 50%, compression and post-tension method of the screw end rod is not restricted.
