The weight of the steel pipe is one of the most important parameters in the process of transfer of steel ownership, which determines the fair and just weight calculation of the steel pipe in the process of steel pipe operation: theoretical weight calculation and weighing weight, which is commonly known as "adjustment" and "weighing". The theoretical weight is calculated by the theoretical data of the steel pipe (the outer diameter, wall thickness, and length of the steel pipe actually measured) through the mathematical formula, the formula is:
The weight of steel pipe per meter = (outer diameter - wall thickness) * wall thickness *, the unit of this value is kg; Weighing is the weight of the steel pipe actually weighed by weighing tools such as weighbridges or hanging scales. Fundamentally, spiral steel pipes or longitudinal seam steel pipes are a type of welded steel pipes, and due to their superior performance, these two types of steel pipes are widely used in various projects. Of course, due to their different production processes, there are still great differences in the actual use process, which directly leads to a great difference in the scope of application of the two types of steel pipes.
If you have any questions or do not understand, you can consult Huayang Steel Pipe. The company focuses on the development, sales and service of steel pipes, and provides high-quality products for many industry enterprises. The company has introduced the one-time row rolling forming process from Germany, and the digital control equipment of the British CT company METORI can produce welded pipes and expanded pipes of various diameters.

The inner wall, outer wall, section and section of the seamless steel pipe cannot be seen as welded. Because the seamless steel pipe is a one-time forming product, it has not undergone the later stages of rolling, welding and other processes. Regardless of the section, inner wall, outer wall or section, as long as there is a weld, it is not a seamless steel pipe.
The products that cannot see the weld on the inner wall but can see the weld on the outer wall are all fakes or polished goods. Some products that do not have welds on the outer wall without friction are seamlessly treated steel pipes and are polished goods. **It is a lot different from a real seamless steel pipe.
Some are undesirable and hurtful, confusing concepts, and making illegal profits.

How much does a pipe weld cost?
In terms of foreign-funded projects, the contractor's ** is generally about 45 yuan per inch of carbon steel, about 60 yuan per inch of stainless steel, about 150 yuan per inch of titanium and nickel, and the coefficient of high-pressure thick-walled pipes is generally multiplied, and the unit price of 100% flaw detection should be appropriately increased; In addition, it is necessary to consider whether to carry out post-weld heat treatment, and the cost will increase; The requirements for foreign-funded projects are stricter, each welder completes about 40 inches a day, the welder's salary is 300 yuan a day, the labor cost is about an inch of money, and the rest is the cost of materials, machinery, flaw detection, etc. My friend You are very welcome to use the know, I am the teacher who knows the answer! I've seen your question, and I'll do it next, typing is a little slow, and it takes a little time, so please be patient.

How much does a pipe weld cost?
30-40 yuan per inch diameter, depending on the situation you discussed. Regardless of meters, on the size of the weld, now package the installation of welding cleaning workers. 100 pipes, 4 inch diameter, 10 crossings a day can be completed easily (8 hours of work, wall thickness of about 6mm), 2 plumbers, 2 welders, half gas welding, this is a group, two groups, a total of 9 people, a day to get 40-60 crossings, no problem.

Summary. The fractions and inches of a water pipe are calculated in inches. One inch is 25mm, two inches is 50mm, three inches is 75mm, four inches is 100mm, and so on.
Get: 16 pipes are four pipes, 20 pipes are six pipes, 25 pipes are one inch pipes, 32 pipes are two inches, 40 pipes are two inches, 50 pipes are two inches, etc. Generally speaking, the diameter of the water pipe is called according to the diameter of the imperial pipe.
For example, 1 2 inches is equal to 15 mm in the metric system;1 inch is equal to 8 cents, which is equivalent to the metric system; 6 mins 3 4 inches 20mm; 4 minutes 1 2 inches 15mm.
How much does a pipe weld cost?
Just did a plumbing job, and the contractor was 35 yuan per inch. Is this inch calculated by circumference.
Hello. The ** of pipeline welding is 120 yuan, and the pipeline welding process is the key process and main process of steel pressure pipeline engineering construction. The quality of pressure pipeline formation and welding directly affects the flow rate and flow direction of pipeline medium, pipeline wear and safe operation.
Therefore, there are extremely strict requirements for the welding quality of pressure pipes, except for the requirement that the welded joints are fully penetrated welds.
Inches are calculated by circumference.
Welding and cleaning labor ** is calculated according to the set of quotas, 1 inch pipe is about 14 yuan to 20 yuan, 2 inch pipe is about 35 yuan to 40 yuan, and the unit price labor cost of 6 points is 6-7 yuan. There is also a large pipe, which is expensive, because the welding needs to be caulked, and the welding needs to be completed several times. For example, a weld of DN300 pipe is 120 yuan to 140 yuan, and a weld of DN400 pipe is 160 yuan to 180 yuan.
The larger the pipe, the more expensive it is.
Pipe with a diameter of 1420 mm, 35 an inch. How should this mouth be calculated?
The fractions and inches of a water pipe are calculated in inches. One inch is 25mm, two inches is 50mm, three inches is 75mm, four inches is 100mm, and so on. Get:
16 pipes are four pipes, 20 pipes are six pipes, 25 pipes are one inch pipes, 32 pipes are two inches, 40 pipes are two inches, 50 pipes are two inches and so on. Generally speaking, the diameter of the water pipe is called according to the diameter of the imperial pipe. For example, 1 2 inches is equal to 15 mm in the metric system;
1 inch is equal to 8 cents, which is equivalent to the metric system; 6 mins 3 4 inches 20mm; 4 minutes 1 2 inches 15mm.
Pipe with a diameter of 1420 mm, 35 yuan an inch. How should this mouth be calculated? How much does this mouth dry out.
A pipe with a diameter of 1420 mm, an inch of mouth, that's 56 mouths. 35 yuan a mouth, that is about 1960 yuan.
I thought it was the circumference divided by the inches and multiplied by an inch of thirty-five dollars.
That's not how it works.

Welded steel pipe, also known as welded pipe, is a steel pipe made of steel plate or strip steel after being curled and formed, generally with a fixed length of 6 meters. The production process of welded steel pipe is simple, the production efficiency is high, the variety and specification are many, and the equipment investment is less, but the general strength is lower than that of seamless steel pipe. >>>More
Stress tube: electrical stress control is to control the electric field distribution and electric field strength inside the cable accessories, that is, to take appropriate measures to make the electric field distribution and electric field strength in the best state, so as to improve the reliability and service life of the cable accessories. For the cable termination, the electric field distortion is the most serious, and the biggest impact on the reliability of the terminal operation is the cable outer shield cut-off, and the influence of the electric field distortion of the cable intermediate joint, in addition to the cable outer shield cut-off, there is also the cable end insulation cut-off. >>>More
