WPL3 tee

When processing WPL3 tee, some processes need to be operated under the condition of welding and heating WPL3 tee, which plays a major role in the quality of WPL3 tee products

During the processing of WPL3 tees, the control of the processing temperature of WPL3 tees is a key point. In addition, it should be noted that the billet should be heated evenly to abide by the contract. The piercing has a great impact on the quality. The welding temperature of the blank varies according to the material, generally around 1200 ℃

How to reduce the oxide scale of WPL3 tee is the two key points of WPL3 tee heating operation. Pay special attention to hot kneading. Starting from the service life of tools and the surface quality of kneaded pipes, the requirements are more strict. For example, furnaces for heating are divided into heating furnace and reheating furnace according to their functions; The former is used to heat the blank from normal temperature to processing temperature; The latter is used to reheat the blank to the agreed processing temperature during processing

There are many forms of WPL3 three-way heating furnace, but the annular heating furnace is mainly used. This kind of heating furnace has an annular furnace bottom, which can rotate slowly. The billets are loaded along the diameter direction of the furnace bottom from the inlet. Once the furnace at the outlet is used, it can be heated and homogenized to the specified temperature. In this way, WPL3 three-way pipes can be heated uniformly
