Seamless Pipe Fittings 1D 1.5D 90 Degree Carbon Steel Butt Welding Elbow For Gas Line / Oil Line

1D 1.5D 90 Degree Elbow Seamless Pipe Fittings​

Product Description:

carbon steel elbow is belongs to one type of pipe fittings which is used into the gas line , oil line for base construction which is important in the whole transport line . Carbon steel elbow have many type: butt-weld type .socket -weld type and etc. In my company we are mainly working on the Butt Welded pipe fitting . Every month have exported more than 50 containers carbon steel pipe fittings to all over the world. And we have got good feedback from our old customers and we built long terms relationship . Carbon steel elbow now is the most needed in all kind of pipe fittings.

Introduction to carbon steel seamless elbow
Carbon steel seamless elbow forming technology is the special elbow tube parts of the push machine, core mold and heating equipment, seamless elbow manufacturers so that the blank on the mold in the push machine forward, in the process of heating, expanding and zigzag forming.Hot pushing elbow pipes deformation characteristics is based on volume before and after plastic deformation rule of metal materials concluded that tube billet diameter, chooses the pipe diameter is less than the diameter of the elbow pipe fittings, through core model control billet deformation process, the arc is tight spot metal activity, counter to other parts of the thinned by expanding, then get the uniform wall thickness of elbow pipe fittings.



Seamless elbow type:

Carbon steel seamless elbow data variety, widely used, is forming a large-scale high-tech industrial group, has a very broad market prospects and very important strategic meaning.High pressure elbow bend tube data in accordance with the classification standard classification can be divided into innovative varieties, because we have electronic information alone idle a new type of data field, proud of the new wear data is in addition to electronic information outside the main wear data.

Carbon steel seamless elbow push seamless elbow resistance to air, steam, water and other weak erosion medium and acid, alkali, salt and other chemical erosion medium corrosion steel.Also known as stainless acid steel.In practice, the steel resistant to weak erosion medium is called stainless steel stamping elbow, and the steel resistant to chemical erosion medium is called acid resistant steel.Because of the difference in chemical formation f between the two, the former is not different from the chemical medium corrosion resistance, the latter are generally rustless.Cr-containing stainless steel stamping elbow also integrates mechanical strength and high elongation, easy to process and manufacture components, which can meet the needs of architects and structural designers.

Seamless elbow classification:

A seamless bend is a fitting for a bend in a pipe.In the total pipe fittings used in the pipeline system, the proportion is the largest, about 80%.Generally, different forming processes are selected for the elbows with different material wall thickness.At present.The forming process of seamless elbow commonly used by manufacturers includes hot pushing, stamping, extrusion, etc

Seamless elbow is also called seamless steel pipe elbow, seamless elbow pipe fitting due to its manufacturing process, and divided into hot rolling (extrusion) seamless elbow pipe fitting and cold drawing (rolling) seamless elbow pipe fitting two kinds.Cold drawn (rolled) tube is divided into round tube and shaped tube two kinds.

The raw material for rolling seamless elbow pipe fittings is round tube blank. The round tube blank is cut by cutting machine and processed into blank with a length of about one meter, and then sent to the furnace by conveyor belt for heating.The billets are fed into a furnace and heated at a temperature of about 1200 degrees Celsius.The fuel is hydrogen or acetylene.The temperature control in the furnace is the key problem.Generally more common puncher is tapered roller puncher, this kind of puncher has high production efficiency, good product quality, large perforation diameter, can wear a variety of pipe fittings.After perforating, the round tube blank is successively rolled, rolled or squeezed by three high.After extrusion, take off the pipe to determine the diameter.The sizing machine rotates the tapered bit into the steel blank to punch holes at high speed to form the pipe fitting
