The advantages of seamless elbow and production process  

The advantages of seamless elbow: seamless elbow has the advantages of light weight, good heat resistance, good corrosion resistance, good heat preservation, good impact resistance, long service life.  Seamless elbow in the introduction of light weight is the so-called stamping elbow density of 0.89-0.911g/cm, one tenth of the steel pipe, due to light weight, can greatly reduce the industrial transportation costs and installation of the construction intensity.  Seamless elbow of good heat resistance: working water temperature of 70 degrees, softening temperature of 140 degrees.  Good corrosion resistance, in addition to a few hydrogenating agents, can resist the erosion of a variety of media, with excellent acid resistance, alkali resistance, corrosion resistance, no rust, no electrochemical corrosion.  

 Seamless elbow has good heat resistance, the water temperature is 70 degrees during the working process, and the softening temperature is 140 degrees.  

 Seamless elbow production process: seamless elbow will not produce corrosion, pitting, rust and wear.  Stainless steel is one of the building material of metal materials in high strength, because the stainless steel has good corrosion resistance, so he can make structure parts permanently maintain the integrity of engineering design, raw materials are tubular billet rolling seamless elbow fittings, pipe billet through cutting machine processing and the length of the billet is about one meter, and unknown to heating furnace, the billet was sent within the charging heating,  The temperature is about 1200 degrees Celsius, and the temperature control in the furnace is the key issue. The billet comes out of the furnace and is perforated under pressure. The fuel is either hydrogen or acetylene.  

 Generally, the more common punching machine is conical, which has high production efficiency, good product quality and large amount of perforation enlargement. After perforating a variety of holes, the round tube billet is successively rolled by three-roll cross rolling, continuous rolling or extrusion. After extrusion, the tube is removed and the diameter is set, and the sizing machine rotates into the billet through the conical drill at high speed to punch holes to form pipe fittings.  

 Seamless elbow is a common pipe fitting used for pipe hair bend. In the pipe fitting used in the pipeline system, the proportion is 80%.  The common forming process of seamless elbow is hot push, stamping, extrusion and so on.
