Welded steel components accounting formula

(C) steel pipe accounting formula

      × L × steel proportion of welded steel components accounting: kg / m = (OD - Wall Thickness) * 0.02466 steel pipe wall thickness * accounting methods: the weight of the steel pipe = 0.25 × of π × (external diameter square - inside diameter squared): π = 3.14 L = Pipe length steel proportion take 7.8 Therefore, the steel tube weight = 0.25 × 3.14 × (external diameter squared - diameter squared) x L x 7.8 * If the size of unit to take m (M), the accounting component consequences kg (Kg)

Welded steel classification and useful

A low pressure fluid walks welded steel pipe (GB/T3092-1993), also known as ordinary pipe, commonly known as the clarinet. Welded steel pipe is used for the ordinary walks of water, gas, air, oil and steam heating the lower pressure fluid, and other useful. Steel pipe connected to the wall thickness is Pided into the popular steel and thicker steel pipe; the receiving end is Pided into without the steel pipe (fluorescent tubes) and with a steel pipe. The specifications of the tubes nominal diameter (mm) revealed that the performance of the nominal diameter is the diameter of the approximation. Habits used in. disclose performance, such as 11/2 and so on. The low pressure fluid walks welded steel pipe for walks fluid, but also as a low pressure fluid walks galvanized welded steel pipe of the original tube.

(2) low pressure fluid walks galvanized welded steel pipe (GB/T3091-1993), also known as galvanized welded steel pipe, commonly known as the white tube. Is used in the ordinary walks of water, gas, air, oil and steam heating, warm water and other lower pressure fluid or other useful hot-dip galvanized welding (furnace welding or welded) steel tubes. Steel pipe connected to the wall thickness is Pided into popular galvanized steel and thicker galvanized steel; receiving end into the threaded galvanized steel pipe and threaded galvanized steel pipe. The specifications of the tubes nominal diameter (mm) revealed that the performance of the nominal diameter is the diameter of the approximation. Habits used in. disclose performance, such as 11/2 and so on.

Steel pipe pressure to plastic for easy welding and molding process; through various types of severe and scientific inspection and testing, the use of safe prison *, large diameter steel pipe, high efficiency, walks, and can throttle the laying of the pipeline investment. Primary for the laying of walks of oil, natural gas and other pipeline.

Caliber, high efficiency, walks, and can throttle the laying of pipeline investments. Primary for the laying of walks of oil, natural gas and other pipeline.

Ordinary low pressure fluid walks with spiral submerged arc welded pipe (SY5037-83) for billet is hot rolled steel strip coils, often warm spiral shape, with double-sided initiative submerged arc welding or single-sided welding into the legal system for ordinary low-pressure fluid such as water, gas, air and steam walks using the submerged arc welded pipe.

Eight general low pressure fluid walks with spiral high-frequency welded steel pipe (SY5039-83) is hot-rolled steel strip coils for tube, often warm spiral shape, using high-frequency overlap welding Welding method for ordinary low-pressure fluid walks with spiral seam high frequency welded steel pipe.

9. Pile for the tube, spiral welded steel pipe (SY5040-83) is hot-rolled steel strip coils, often warm spiral shape, made of double-sided submerged arc welding or high frequency welding for the civil construction of structures, quays, bridges such as foundation piles with steel pipe.

     Welded steel pipe, also known as pipe, steel pipe is made of welded steel sheet or strip through the curl forming. Welded steel producing process briefly produced in high efficiency, types of specifications, and less investment in equipment, but the ordinary strength is less than seamless steel pipe. 30 years since the 20th century, followed by the production of high-quality steel strip rolling agility to carry out welding and inspection of the enhancement of skills, from time to time progress of weld quality, increasing number of types of welded steel specifications, and more and more areas instead of pipe joints. Welded steel pipe weld way into a straight seam welded pipe and spiral welded pipe. Longitudinal produced in the process briefly, produced in high efficiency, low capital, to carry out faster. Common than the strength of the spiral welded pipe Longitudinal high, can narrow the billet produced large diameter pipe, the pipe diameter differences can also be produced with the same width of the blank. What, then, be compared with the same length of straight seam pipe, weld length add 30 to 100%, and produced the lower rate. Thus, smaller diameter pipe mostly straight seam welded pipe of large diameter are mostly spiral welded.
