Application principle of hot pressing elbow

Application principle of hot pressing elbow

The company is to push the elbow manufacturers: the use of hot pressing elbow principle, reduce residual stress, together can reduce hardness, improve plasticity and endurance, improve the cutting function.Mechanical function test of elbow:NDT can find connotation of weld defects, but can't clarify how affect the mechanical function of the metal welds, which sometimes butt joint is to be a pull and twist of impact test, such as stainless steel stamping elbow is handed in bumper stamping elbow was due to his corrosion resistance, not easy to rust, it also should pay attention to when using stainless steel stamping elbow protection,Avoid rust of stainless steel stamping elbow.The above experiments are the experimental results of our company for many years.The experiment is welded together with the longitudinal seam of the cylinder to ensure the same construction conditions.

Where is the hometown of elbow pipe fittings elbow as long as the production of advanced in our Hebei Mengcun, our company is also in the development zone of the elbow capital.Our company is close to the Beijing-Shanghai high-speed railway, Beijing-Shanghai high-speed, Shihuang high-speed, Jinshan high-speed, geographical location in the corner of the village.Transportation is more convenient.The company's main production of elbow self - marketing push.Have their own production line.At present, our factory is one of the heating industry pipe fittings products.Elbow can obtain the favor of the market, and constantly replace some traditional wear-resistant materials.The quality of products is mainly divided into.As well as with traditional wear materials.Commonly used seamless steel pipe manufacturers manufacture hot push when Hebei pipe fitting extrusion elbow.Method for manufacturing butt welding elbows.Usually the medium frequency and high frequency induction heating method, the flame heating method.Pipe corrosion usually shows thinning of the pipe wall, a local pit and pitting.
