Q:What type of steel pipe for security windows?
Stainless steel security window generally use 25 square tubes and 19 round tubes! 25/38 tubes and 22 round tubes are also available!
Q:What does seamless steel tube mean? What are the main uses? What are the classifications?
Seamless steel pipe having a hollow cross section, used as a conduit for conveying fluids, such as pipelines for transporting petroleum, natural gas, gas, water, and certain solid materials. Compared withsteel and roundsteelinsolid, flexural torsional strength in the same time, the weight is light, is a kind of economic section steel, widely used in the manufacture of structural parts and mechanical parts, such as the oil pipe, automobile transmission shaft, the bicycle frame and steel construction with scaffold with steel pipe manufacturing ring parts can be improved the utilization rate of materials, simplify the manufacturing process, material saving and working hours, has been widely used to manufacture steel tube.
Q:What's the actual size of the DN25?
DN25 refers to the theoretical size of the inner hole of the pipe. That is to say, the theoretical dimension of the inner diameter of the pipe is 25 (the metric tube refers to the inner diameter, and the English tube is also to indicate the inner diameter, for example: 3/8, the inner diameter is 9.525, and the diameter of the 1/2 is 12.7, and the diameter of the 5/8 is 15.875). The outer diameter is theoretical in diameter, plus the wall thickness specified by the state (which is artificially specified and has no formula)The theoretical diameter of DN25 is 25, and the outer diameter is Phi 33.7 and phi 32(but there is also the outside diameter of the mark. The mark is: the outer diameter * wall thickness, such as: 32 * 2, that is to say, the outer diameter is 30, the inner diameter is 26)
Q:What does cathodic protection of steel tubes mean?
The corrosion of metals causes great economic losses directly or indirectly. Foreign statistics show that every year due to corrosion and scrap metal materials, equivalent to 20~40% of metal production, the world every year due to corrosion and loss of metal reached more than 1 tons.
Q:Galvanized steel pipe, PPR pipe, PE pipe, U-PVC pipe and HDPE double wall corrugated pipe and what is the difference between the characteristics of
PE pipe, polyethylene pipe, the past is also commonly used in low temperature water, but because of its short life now use less prone to aging, more PE material for the production of plastic bags;
Q:Difference between seamless steel pipe and welded pipe
Welded steel pipe for different welding process and divided into the furnace pipe welding (ERW) pipe and automatic arc welding, because of the different forms of welding seam welded pipe and spiral welded pipe is divided into two kinds, end its shape is divided into circular welded and shaped (square) pipe etc..
Q:What is the difference between seamless steel pipe and welded pipe?
The thicker the diameter, the more commonly the spiral weld. The seamless steel pipe is generally molten state molten steel through the annular slot backlog, and then stretched and other treatment process, so that there is no weld. On the performance, especially the pressure capacity of the steel pipe than ordinary steel has greatly improved, so often used for high voltage equipment.
Q:Galvanized steel pipe DN100 and SC100
Zinc plating, hot dip galvanizing and cold galvanizing, to see the design instructions and design requirements, which will explain
Q:What does "1.5" steel tube mean?
1.5 inch [1 1/2 steel pipe, outer diameter 48.3mm, 1.5 inches, refers to the pipe bore is approximately the inner diameter (25.4x1.5 = 38.1mm). [DN40] the specific parameters of the steel pipe are as follows;The average wall thickness is: 3.5mm;The minimum wall thickness is 3.06mm,Nominal diameter is 40mm,External Jing is 48.3mm,
Q:What's the difference between stainless steel seamless tube and stainless steel welded pipe?
Stainless steel seamless steel tube is a kind of steel strip with hollow section and without seams.
