What kind of elbow is called a hot pressed elbow  

Our company mainly produces all kinds of different materials of elbow fittings, such as carbon steel, alloy steel, stainless steel, elbow, tee, size head, pipe cap, flange and other pipe fittings series.  The company has many years of production experience in the above pipe fittings products, using advanced equipment to test each product, to provide customers with qualified pipe fittings products.  Our company based on science and technology, the principle of integrity management, so that every customer in the company to order satisfactory pipe fittings products, welcome new and old customers to visit.  

Thermal bend is fabricated by hot-pressing process an elbow pipe, hot bend pipe is heated with the commonly used equipment shaping after hot cutting heated to above a certain temperature, heat preservation after a period of time in the quenching soon, is to reduce the temperature suddenly, at a speed greater than the critical cooling cooling methods and bend pipe fittings.  

The quenching of hot pressed elbow is to heat the elbow to the critical temperature above, hold for a period of time, and then quickly put in the quenching agent, is its temperature suddenly reduced, to cool more than the critical cooling rate, obtain different treatment methods.  Quenching can increase the strength and hardness of steel, but to reduce its plasticity, the commonly used quenching agents are: water, oil, alkaline water and salt solution.  

The normalizing of hot pressed elbow: the normalizing is the heat treatment method of heating the hot pressed elbow to a certain temperature above, which is the uniform wall thickness of the hot pressed elbow, and then the natural cooling in the air.  The above is our company in the production of hot pressed elbow pipe fitting process.
