the proportion is large, about 80

in the pipe system, the proportion is large, about 80%. Generally, different forming processes are selected for elbows with different material and wall thickness. At present. The forming process of seamless elbow commonly used in the manufacturer includes hot pushing, stamping, extrusion, etc. The raw material for rolling seamless elbow pipe fittings is round tube blank. The round tube blank needs to be cut and processed by the cutting machine with a growth of about one meter, and sent to the furnace for heating through the conveyor belt. The billet is heated in a furnace at a temperature of about 1200 degrees Celsius. The higher the carbon content, the higher the hardness, the higher the strength, but the lower the plasticity. It mainly refers to the steel whose mechanical properties depend on the carbon content in the steel, and which generally does not add a lot of alloy elements, sometimes it is also called ordinary carbon steel or carbon steel. Carbon steel, also known as carbon steel, refers to iron carbon alloy with carbon content of WC less than 2%. The die used for stamping elbow is called stamping die, which is called stamping die for short. Stamping die is a special tool for batch processing site materials (metal or non-metal) into required stamping parts. Stamping die is very important in stamping. Without the required stamping die, batch stamping production is difficult to carry out; without advanced stamping die, advanced stamping process cannot be realized. Stamping process and die, Stamping equipment and stamping materials constitute the three elements of stamping processing, only when they are combined with each other can stamping parts be obtained.

The curvature radius should be controlled in the process of producing long radius elbow. For example, if the radius length is 1.5D, the radius of curvature must be within the required tolerance. As most of these pipe fittings are used for welding, in order to improve the welding quality, the ends are beveled, with a certain angle and a certain edge, which is also relatively strict. There are provisions for how many sides are thick, how many angles and deviation ranges, and many more geometric dimensions than the pipe fittings. The pipe bender must be well grounded when it is used. The conductor of the equipment shall not be less than 4mm. When it is used, it is not allowed to connect the power supply and voltage beyond the fixed range. It is not allowed to plug in and plug in the plug-in with power on, and it is not allowed to test the control circuit with a megger. The position of the proximity switch in the pipe bender cannot be impacted by hard objects. The equipment needs to add lubricating oil to the chain and other sliding parts on a regular basis. When the equipment is plugging and unplugging the connector, it is not allowed to pull the wire or cable to prevent the welding from pulling off. The raw material for rolling seamless elbow pipe fittings is round tube blank. The round tube blank needs to be cut and processed by the cutting machine with a growth of about one meter, and sent to the furnace for heating through the conveyor belt. Seamless elbows account for about 80% of all the pipe fittings used in the pipeline system. Generally, different forming processes are selected for elbows with different material and wall thickness. The billet is heated in a furnace at a temperature of about 1200 degrees Celsius. The fuel is hydrogen or acetylene. The temperature control in the furnace is a key problem. After the round tube billet is discharged, it needs to be pierced by a pressure piercer. stainless steel elbow has high connection strength and anti vibrationThe connection part shall be fixed firmly to avoid the possibility of "flexible joint" loosening. The construction is convenient and fast to avoid field welding operation and threading operation. The service life of stainless steel elbow is long. According to the field corrosion test data, the service life of stainless steel elbow is up to 100 years, and almost no maintenance is needed for stainless steel elbow. Therefore, the performance price ratio is very good, the operation life cost is low, and the economic benefit is significant. Stainless steel elbow is very convenient to install on site. Cr, Al, Si and other elements can improve the oxidation resistance and high temperature gas corrosion resistance of WB36 heavy wall alloy elbow, but excessive Al and Si will make the steel thermoplastic deterioration. Nickel is mainly used to form and stabilize austenite structure, so that steel can obtain good mechanical properties, corrosion resistance and technological properties. Molybdenum can passivate stainless and acid resistant steel quickly and improve the corrosion resistance of solutions containing chloride ions and other non oxidizing media. Titanium and niobium are usually used to fix the carbon in the alloy seamless elbow and make it form stable carbide, so as to reduce the harmful effect of carbon on the corrosion resistance of the alloy seamless elbow. Quenching can increase the strength and hardness of steel, but reduce its plasticity. The commonly used quenchants in quenching are: water, oil, alkali water and salt solution, etc. Normalizing is a heat treatment method that heating the high-pressure seamless elbow above the critical temperature, making the high-pressure seamless elbow all change into uniform austenite, and then cooling naturally in the air.
