Tank heads (also called elliptical head or elliptical dish end) is usually made with Carbon steel, stainless steel, austenitic and non ferritic metals that can be cold worked. The shape of this tank heads is more economical, because the height of the head is just a fraction of the diameter. Its radius varies between the major and minor axis usually with the ratio is 2:1. The tank heads is the economical solution for medium pressure tanks due to the reduced metal thickness requirement.
Our long term partner in Xinjiang province ordered six large tank heads in early March. Two tank heads with the diameter of 7.4 meters, four tank heads with the diameter of 6 meters. We manufactured these tank heads with material Q345R carbon steel plate.The Q345R carbon steel plate thickness was 30mm.Due to the larger diameter, at first we used a few pieces of Q345R carbon steel plates to weld into large steel plates. After welding, we did ray inspection for these large steel plates. After passing the ray inspection, cutting the materials, then proceeded the forming process. Forming process was divided into hot pressing and cold pressing. Due to the large diameter, it was impossible to do hot pressing. We used cold pressing.

Cold pressing was mainly performed with a spinning machine. After spinning, the dished head was tested. After passing the test, the customer asked us to spray paint.The customer requested that the surface and interior of tank heads should be painted with grey color. It looks very nice. Due to the larger diameter, we cut the 6 tank heads into 12 pieces for easy transport. Delivery date is 30 days. We finished the order on time.These heads can be delivered next week.
