The introduction of carbon steel elbows, recommended by carbon steel elbow manufacturers

Carbon steel elbow is a metal pipe fitting that changes the direction of the pipe on the carbon steel pipe. The connection method is threaded and welded. According to the angle, there are 45° and 90°180° three most commonly used, in addition to 60° and other abnormal angle elbows according to the needs of the project.

The materials of elbows are cast iron, stainless steel, alloy steel, malleable cast iron, carbon steel, non-ferrous metals and plastics. The methods of connection with the pipe are: direct welding (the most commonly used method) flange connection, hot melt connection, electric fusion connection, threaded connection and socket connection.

According to the production process, it can be divided into: welding elbow, stamping elbow, pushing elbow, casting elbow, etc. Other Names:

90-degree bend, right-angle bend, love bend, etc.

Carbon steel butt welded pipe fittings are one of the most widely used materials in welded pipe fittings. Carbon steel, also known as carbon steel, refers to an iron-carbon alloy with a carbon content less than WC.

In addition to carbon, carbon steel generally contains a small amount of silicon, manganese, sulfur and phosphorus. Butt welded pipe fittings are pipe fittings made of welded pipes, for pipe fittings manufacturing plants, the forming process of using welded pipes is basically the same as the forming process of using seamless pipes, and the forming process of butt welded pipe fittings does not include welding processes; The other is to complete the carbon steel pipe fittings by the pipe fitting manufacturing plant.

The butt welding flange of the welding process required for forming is one of the flange pipe fittings, which is widely used and promoted in different fields and industries, and the scope of application in use is different, and the environment that needs to be used is also different, and it needs to be used according to certain conditions. The butt welding elbow is completed by welding two steel plates, and the general large-diameter elbow is this process, and the general diameter above 600 is basically the butt welding elbow. [1]

When we install pipelines in our projects, there is often a phenomenon of bending, so in the peak season we need an elbow to change the direction of the metal pipe. Carbon steel elbow is to change a group of metal pipe fittings above the carbon steel pipe, so the application of this pipe fitting is very extensive, and I will introduce several carbon steel elbow manufacturers for your reference when purchasing.

Carbon steel seamless elbow is a very common material used in elbows, which is cheap and easy to use. According to the material, it is divided into: low carbon steel, medium carbon steel, high carbon steel, No. 20 steel (20g), Q235A, Q235B, etc., which is characterized by relatively high carbon content; According to the standard, it is divided into:

The raw material of carbon steel seamless elbow is seamless steel pipe, and the main production process is round tube billet Heating Perforation Three-roll skew rolling, continuous rolling or extrusion Pipe removal Sizing (or reducing diameter) Cooling Straightening Hydrostatic test (or flaw detection) Marking Warehousing. Schxx is the wall thickness grade, and 90E(S) indicates a carbon steel elbow with a short radius of 90 degrees; 90e(l) represents a long radius 90 degree elbow; 45e(l) represents a long radius 45 degree elbow; 45e(s) represents a short radius of 45 degree elbow; 180e(s) represents a carbon steel elbow with a short radius of 180 degrees; 180e(l) represents a long radius 180 degree elbow;

The principle of determining the heating temperature of the carbon steel elbow is that the material is above the austenitization temperature, and the main compressive stress of the inner wall of the elbow is less than the yield limit of the material at this temperature. The higher the austenitization temperature of the material, the higher the heating temperature; The higher the yield limit of the material at high temperature, the higher the heating temperature, and the advantages of carbon steel seamless elbows.

1.The materials of the seamless elbow are all composed of carbon and hydrogen, and absolutely no toxic substances will be added, and the material of the seamless elbow has been tested by the relevant national departments, so you can rest assured that it is hygienic.

2. The weight of the seamless elbow is only one-tenth of the steel pipe, you can imagine how light it is, and the manuscript chain greatly reduces the cost of transportation, and it is also very convenient during installation and construction. 3. The heat resistance of the seamless elbow is good, why do you say so? For example, when the working water temperature is 70°C, the softening temperature is 140°C.

So there is no need to worry about its heat resistance at all.

4. The corrosion resistance of the seamless elbow is also very strong, not only will it not rust, but also will not breed bacteria, except for a few hydrogenating agents, of course.

5. Good thermal insulation performance, which should be known to everyone. Because the seamless elbow material has low thermal conductivity, it is very good relative to thermal insulation.

6. The impact strength performance of the seamless elbow is much stronger than that of other solid wall pipes, and it is twice that of the solid wall. So it has a strong impact resistance.

7. Another point has to be mentioned, the service life of the stamping elbow is very long, it is said that it can reach more than 50 years, because it is under the rated temperature and pressure, so that it not only emits radiation and ultraviolet rays, but also makes the product never fade.

Summary: The above is the relevant content of the advantages of carbon steel seamless elbows, I hope to explain to friends who have this demand! For more information, please continue to ******. More exciting content will be presented in the future.

Stainless steel elbows can be kept for a long time without corrosion and rust, and ° elbows can be produced according to the standard.

Carbon steel elbow is a metal pipe fitting that changes the direction of the pipeline on the carbon steel pipeline, which is divided into three most commonly used according to the angle: 45 ° and 90 ° 180 °, and also includes other abnormal angle elbows such as 60 ° according to the needs of the project.

1. Stainless steel is more corrosion-resistant than carbon steel; Stainless steel is more malleable than carbon steel. Stainless steel elbows will not be uniformly corroded like carbon steel elbows, and no protective coating is required for application; The stainless steel elbow is strong, and the possibility of stainless steel water pipe leakage is extremely small when it is hit by external forces.

2. Stainless steel contains more chromium and nickel metals, so the appearance color is mostly silver and bright, and the surface is smooth and has a strong metallic luster. The main color of carbon steel is the color of iron, which will be much darker.

3. In terms of wear resistance, carbon steel elbow has other advantages and uses, and carbon steel elbow vertical liquid head is a kind of pipe fitting commonly used in pipeline installation, which is used for connection at the bend of the pipeline. Carbon steel has good wear resistance and toughness, the production process is simple, the comprehensive economy is reasonable, and it is applicable under many conditions, and is welcomed by users. This also makes the application of thick-walled and resistant hall grinding elbows more extensive, and the cost is more and more cheap.

Elbows have stamping elbows, push elbows, forged elbows, cast elbows, thread elbows, socket elbows, coil welded grooved elbows.

The bending radius r= of r= r= of r=, commonly known as elbows and more than is called elbows.

The outer diameter of the elbow is almost a millimeter, which can be counted as a model.

You ask about the "model" instead of the specs, right? In fact, there is no type of elbow, only form: inner wire elbow on water gas pipeline, flange elbow and socket elbow, shrimp elbow on carbon steel pipeline.

Stamping elbows and simmering elbows on seamless pipes, grooved elbows for groove connections, integral calcining elbows on high-pressure pipelines, etc.

You should be asking about welding elbows.

Nominal diameter dn

Stainless steel is slightly heavier, and the density of stainless steel is greater than that of carbon steel.

Hebei Haoguan elbow pipe fittings manufacturing **** specializes in the production of various specifications of elbows and pipe fittings.

Because the density of carbon steel and stainless steel is not the same, the coefficient between them is also different. The coefficient of carbon steel is and the coefficient of stainless steel is , of which the coefficient of stainless steel 316L material can be reached.

It's not the same, because its density and specific gravity are different, carbon steel is, stainless steel is.

There is a slight difference. The material composition is different, and the density is different.

Weight doesn't seem to matter here.

Carbon steel elbows made of carbon steel can be divided into the following types:

A3, Q235A, 20G, Q345B, 20G, 16Mn, ASTM, A234, ASTM A105, ST37, ASTM, A403, etc.

Elbows made from these materials can be called carbon steel elbows.

90° carbon steel elbow.

90° carbon steel elbow.

According to the angle of the three commonly used elbows, there are other engineering needs, can be customized such as 60° or other angles.

Connection with carbon steel pipe: welding, flange connection, threaded connection, socket connection and other forms.

According to the process form, it can be divided into: welding elbow, stamping elbow, casting elbow, etc.

Purpose: Connect two pipes to change direction, turn to 45° or 180° and 90° or other angles.

Manufacturing standards: national standard, American standard, Japanese standard, German standard, Russian standard.

The basic process of carbon steel elbow is: firstly, weld a polygonal multi-sided annular shell with a cross-section or a multi-edged fan-shaped shell closed at both ends, after the internal pressure is filled with pressure medium, internal pressure is applied, and the cross-section gradually becomes circular under the action of internal pressure, and finally becomes a circular annular shell. According to the need, a round ring shell can be cut into 4 90° elbows or 6 60° elbows or other elbows, this process is suitable for manufacturing any specification of large elbows with the ratio of the middle diameter of the elbow to the inner diameter of the elbow is greater than the times, and is an ideal method for manufacturing large carbon steel elbows.

The advantages of the carbon steel elbow manufacturing process are mainly manifested in the following aspects:

1) There is no need for pipe blanks as raw materials, which can save the cost of pipe making equipment and molds, and can obtain any carbon steel elbows with large diameter and relatively thin wall thickness.

2) The blank is a flat plate or a spreadable surface, so the blanking is simple, the accuracy is easy to guarantee, and the assembly and welding are convenient.

3) Due to the above two reasons, the manufacturing cycle can be shortened and the production cost can be greatly reduced. Because it does not require any special equipment, it is especially suitable for on-site machining of large carbon steel elbows.

4) Carbon steel elbow is suitable for pipeline series in oil, gas, chemical, hydropower, construction and boiler industries.
