Seamless Pipe Fittings 1/2"-24" A234 Wpb Black Painting Carbon Steel Buttweld

1/2"-24" A234 Wpb Black Painting Carbon Steel Buttweld End Seamless Pipe Fittings

Product Description:

Pipe Fitting has many type such as Butt Welded Elbow, Butt Welded Tee ,Butt Welded Reducer and etc. For the carbon steel elbow , it is big demand for the whole world market. And for Butt Welded Elbow , we have many type such as the long radius carbon steel elbow , short radius elbow , seamless elbow , welded elbow and etc.

Carbon Steel Elbow is one type of the carbon steel pipe fitting which is used widely in the the pipe line such as gas line , oil line and etc. Butt Welded Elbow is made from Induction Heating Elbow Machine and Mandrel Elbow Making Machine. According to the clients requirement,we can select the elbow machine type and after forming the Carbon Steel Elbow ,we need to do beveling , shot blasting , marking and do package according to the requirement. And the Seamless Elbow is belong to butt weld pipe fittings which is one type of welding connect way so we need to do beveling before using the Pipe Fitting.

Seamless elbow technology:

Carbon steel seamless elbow forming technology is to choose the special elbow pipe parts of the push machine, core mold and heating equipment, so that the blank on the mold in the push machine to move forward, in the movement of heating, expanding and zigzag forming process.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.Hot push pipe fitting forming technology has the characteristics of beautiful appearance, uniform wall thickness and continuous work, suitable for mass production, so it has become the primary forming method of carbon steel, alloy steel and carbon steel elbow, and also applied in the forming of some standard stainless steel elbow pipe fitting.The heating methods of the forming process include medium frequency or high frequency induction heating (heating ring can be multi-turn or single turn), flame heating and reflective furnace heating. The choice of heating methods depends on the demand of the forming commodity and the power status of the decision.

technical requirements

1. Since most pipe fittings are used for welding, in order to improve welding quality, the ends are beveled with a certain Angle and a certain edge. This requirement is also strict.The surface mass and mechanical properties are basically the same as the pipe.For the convenience of welding, the fittings are the same type of steel as the connected pipe.

2, that is, all the pipe fittings have to go through the surface treatment, the inner and outer surface of the oxidized iron sheet through the peening treatment, and then painted with anti-corrosion paint.This is for export needs, moreover, in the domestic is also for the convenience of transportation to prevent corrosion and oxidation, must do this aspect of the work.

3, is the requirement for packaging for small pipe fittings, such as exports, we need to make wooden cases, about 1 cubic meter, stipulated that the number of elbows in this kind of box can not exceed 1 ton, the standard allows the set, that is, large set small, but the total weight generally can not exceed 1 ton.For large pieces of y you need a single package, like 24 "you need a single package.Another is the packaging mark, mark is to indicate the size, steel, batch number, manufacturer's trademark.

Classification:

By the production method can be divided into push system, pressing, forging, casting and so on.

It can be divided into national standard, electrical standard, ship standard, chemical standard, water standard, American standard, German standard, Japanese standard, Russian standard and so on.

According to its radius of curvature, it can be divided into long radius elbow and short radius elbow.The long radius elbow refers to the outer diameter of the pipe whose radius of curvature is 1.5 times, that is, R= 1.5d;The short radius elbow means that its radius of curvature is equal to the outside diameter of the pipe, i.e. R= 1.0d.(D is the diameter of the elbow and R is the radius of curvature).

According to the pressure level, there are about 17 kinds, which are the same as the American pipe standard :Sch5s, Sch10s, Sch10, Sch20, Sch30, Sch40s, STD, Sch40, Sch60, Sch80s, XS;Sch80, SCH100, Sch120, Sch140, Sch160, XXS;The most common ones are STD and XS.
