Q345B round steel corrugated tube heat exchanger is on the basis of tube and shell heat exchanger, using special Q345B round steel plate, the top ranking paper roll into a round shape thin-walled tube light, by changing the surface of heat exchange tube shape, exchange heat pipe with double reinforcement, compared with the ordinary heat exchanger, round steel is to monitor the characteristics of thin-walled stainless steel corrugated heat exchange tube, the heat exchange tube using soft mould expanding processing method to form homogeneous continuous corrugated shape inside and outside.
The flow in the bellows is the same diameter beam type and arc flow Q345B round steel stainless steel agent is a relatively helpless matter, Q345B round steel field once again into the wait-and-see situation.Welding current is an important technological parameter of TIG welding. The arc heat is inversely proportional to the welding current. It is necessary to convert the arc power into the secondary power to convert the size of the welding current to complete.When welding, adding welding current can increase the depth and width of welding, so that the plate of Q345B round steel can be welded is increased.In the case of the welding premise and other process parameters unchanged, the welding current of the thin-walled stainless steel plate can only be adjusted outside a certain scale, beyond this category, it will produce welding shortcomings.
