How to make DN400 steel pipe into a 45 degree elbow, and what is the specific process

The angle with the axis is cut off, and a section is reversed, which can be welded into a 45-degree elbow (I have not seen a 45-degree elbow);

The angle with the axis is cut off, and a section is reversed, and it can be welded into a 135-degree elbow.

The above is a two-section one, and a three-section or five-section one will be more sleek.

Steel pipe: Steel pipe is used to transport fluids and powdery solids, exchange heat energy, make mechanical parts and containers, and is also an economical steel. The development of steel pipe production technology began with the rise of the bicycle manufacturing industry, the development of oil in the early 19th century, the manufacture of ships, boilers and airplanes during the two world wars, the manufacture of thermal power boilers after the Second World War, the development of the chemical industry, and the drilling and transportation of oil and gas, all of which have strongly promoted the development of the steel pipe industry in terms of variety, output and quality.

Steel pipes can be divided into two categories according to production methods: seamless steel pipes and seamed steel pipes, and seamed steel pipes are divided into two types: longitudinal seam steel pipes and spiral welded pipes.

Hehe, the steel pipe turning of DN400 should be made into a multi-section elbow, and it is too ugly to make a 45-degree elbow directly. Make a 45-degree turn of the DN400 steel pipe, as long as the end of the two pipes is cut and welded together, it will be bent into a 45-degree angle.

DN400 multiplied by 3 and then multiplied by 60%, it is deduced, not suppressed.

Refer to GB02S403 "Steel Pipe Fittings" page.

Sheet metal calculation software recommended below can easily solve your problem.

DN400 seamless steel pipe 90 degree elbow and 45 degree elbow welded together adjustable height size is 864 mm, here assuming that the elbows are all long radius, see GB T 12459-2017 Table 2 for details.

There's not much to adjust, because if you adjust it, the size won't be right, so you have to press the original size.

The height of the center of the 45-degree elbow of the DN200 steel pipe is 127 mm, and the detailed Bibu is shown in Table 2 of GB T 12459-2017.

The summary is divided into the following steps:

1. Steel pipe elbow production According to the drawings, determine the number of elbow sections (for shrimp elbows) and various indicators, and then cut the seamless pipe (welded pipe should be advanced rolling). The elbow is subjected to a series of tests to ensure that the steel is laminated, and then sandblasted.

2. Bonding ceramics According to customer requirements, suitable ceramics are used for construction. During construction, the ceramics may need to be cut, and the ceramics are cut with a cutting machine with a diamond blade.

3. Spray paint 4, wait for 24 hours, and you can use it normally.

Hope it helps, dear

Summary. Pro, DN1400's steel elbow manufacturing method 1Hot push formingHot push forming in the production method of elbows, one of the more used, need to use a push machine, a mandrel and heating equipment, the tube blank of the finished material is sleeved on the mandrel mold, while pushing, while heating, while forming, this way of production speed is fast, suitable for mass production, and the elbow manufactured, the appearance is beautiful, the thickness is relatively uniform, generally our manufacturers usually use this method for carbon steel elbows.

2.Stamping and stamping forming in the production method of elbow, the number of use is also more, according to the different materials can choose cold pressing or hot pressing, the tube blank is put into the outer die, after the upper and lower die are merged, under the impetus of the press, the tube blank moves along the gap reserved by the inner mold and the outer die to complete the forming process. 3.

In the production method of elbows, for large elbows, two middle plates are cut first, and then half of the elbow profile is pressed by a press, and then the two sections are welded together. The elbow manufactured in this way will have two welds, so our manufacturer must test the weld and only those that meet the standards can leave the factory.

Pro, 1100 steel pipe to make 45 degree elbow practice, as follows.

Dear, for your reference!

Dear, I recommend to you the formula summed up: for example, the slope elbow of 45 degrees, you just need to remember this sentence to know how to do it" Climb 45 degrees, bridge height multiplied by three lines for a bend, hypotenuse is the climbing height multiplied by 30 degrees is the height of the bridge belt and frame multiplied by 45 times 30 divided into three lines for a state line high bend, hypotenuse is the climbing height multiplied by 2 horizontal 90 degree bend is the bridge wide sail scale multiplied by the middle line, hypotenuse (inside) 600 times 200 times 600 below 100.

1.DN40 means that the nominal diameter of the elbow is 40mm, which belongs to the smaller diameter pipe fittings. The nominal diameter affects the size of the bend radius.

245 degrees means that the bending angle of this elbow is 45 degrees. The larger the bending angle, the smaller the bending radius.

3.Socket elbows belong to pipe connectors, and their manufacturing needs to follow the corresponding industry standards, such as GB T 13402-93 "Elbows for Steel Pipes" standard. The standard stipulates that the bending radius of an elbow with a dn less than 50 should not be less than a multiple of the nominal diameter.

4.In addition to the standard requirements, the bending radius is also related to the elbow material, wall thickness, etc. Generally speaking, the softer the elbow material and the thinner the wall thickness, the smaller the minimum permissible bend radius.

In summary, for the 45 degree socket elbow of DN40: 1) According to the GB T 13402-93 standard, its bending radius should not be less than 40*. 2) Considering that DN40 is a smaller diameter, its material and wall thickness will be softer, so the actual bending radius may be less than 60mm, and may be between 50-60mm.

3) A bending angle of 45 degrees will also make its bending radius relatively small. Therefore, the 45 degree socket elbow bend radius of the DN40 may be between 50-60mm, but for a more accurate value, you need to refer to the product manual provided by the manufacturer!
