[Steel Pipe Specification Table] What is the size of the steel pipe?
The steel pipe is used to transfer fluid and powder, exchange heat and produce mechanical parts and containers, and it's also a kind of economical steel. Using steel pipes to manufacture building structure grids, pillars and mechanical supports can reduce weight and save 20-40% of metal, and can realize factory-like mechanized construction. What types of steel pipes are usually available? What is the size of the steel pipe? This article introduces them one by one.
Divide 1 inch into 8 equal parts; 1/8 1/4 3/8 1/2 5/8 3/47/8 inches. It is equivalent to the usual 1-point tube to 7-point tube, and the smaller sizes are represented by 1/16, 1/32, 1/64, and the unit is still inches. If the denominator and the numerator can be reduced (such as the numerator is 2, 4, 8, 16, 32), it should be reduced.
The indication of inches is marked with two strokes in the upper right corner, such as 1/2". For example, the water pipe of DN25 (25mm, the same below) is the imperial 1" water pipe, and it is also the 8-point water pipe before liberation. The DN15 water pipe is the imperial 1/2" water pipe, which is also the 4-point water pipe before liberation. For example, the DN20 water pipe is the imperial 3/4" water pipe, which is also the 6-point water pipe before liberation.
Size DN15 (4 tubes), DN20 (6 tubes), DN25 (1 inch tube), DN32 (1 inch 2 tubes), DN40 (1 inch and a half tube), DN50 (2 inch tube), DN65 (2 inch and a half tube) , DN80 (3-inch tube), DN100 (4-inch tube), DN125 (5-inch tube), DN150 (6-inch tube), DN200 (8-inch tube), DN250 (10-inch tube), etc.
