Q:What's the actual size of the DN25?
Different materials of steel pipe, nominal diameter of the same, then its outer diameter is the same, diameter = outside diameter -2 times, wall thickness.
Q:Hot galvanized steel pipe for use?
1, galvanized layer uniformity: steel pipe sample in copper sulfate solution immersion 5 times continuously, must not turn red (copper plated)2, surface quality: galvanized steel pipe surface should be complete galvanized layer, must not have plating on the black spots and bubbles exist, allow little rough surface and local zinc tumor exists.3, galvanized layer weight: according to the requirements of the buyer, galvanized steel pipe can be used for zinc layer weight determination, its average value should be not less than 500g/ square meters, and any sample shall not be less than 480g/ square meters.
Q:What does "SC50" steel pipe mean in civil engineering?
The corrosion resistance of Ni is very strong in acidic environment. In the environment containing sulfuric acid or hydrochloric acid, the higher the content of Ni in the welded pipe is, the stronger corrosion resistance is. In general circumstances, the addition of Cr in a T-junction steel pipe prevents erosion. The marginal condition of the steel strip is another important cause of the wrong edges. The influence of mass flow rate, heat flux density and structural parameters (ratio of spiral curvature diameter and diameter of T-shape welded tube Dc/D) on heat transfer coefficient of saturated bubble boiling in vertical helical tubes.
Q:SC15 what does galvanized steel pipe look like?
Ordinary galvanized steel pipe, the outer diameter is 1.5 inches
Q:What is the theoretical weight per square meter of the steel pipe diameter of the outer frame and the thickness of the tube wall 3mm 48mm?
Formula: outside diameter - wall thickness * wall thickness *0.02466=, weight per meter! : 48-3*3*0.02466=3.3291
Q:Seamless steel pipe 8162 and 8163 what is the difference?
GB 8162 is the structure of the tube, there is no need for flaw detection, the use of mechanical processing, stents;
Q:What are the uses of welded steel pipes?
It is used to transport water, gas, air, oil and heating steam, and generally lower pressure fluid and other purposes of welded steel pipe. The wall thickness of the steel pipe is divided into ordinary steel pipe and thickened steel pipe. The end of the pipe is divided into non - threaded steel pipe (light pipe) and threaded steel pipe. The specification of steel pipe is expressed by nominal caliber (mm). The nominal diameter is the approximate value of the inner diameter. Usually used in inches, such as 11/2. The welded steel pipe for low pressure fluid transportation is used as the main pipe of galvanized steel pipe for low pressure fluid transportation except for directly conveying fluid
Q:ASME seamless tube how to express, what is the form, I did not find on the ASME, thank God!
You can refer to the ASME B31.10, such as the requirements for the SA106GRB seamless steel tube outer diameter of 168.3 x 7.11, specifications can be marked as NPS6 SCH40 SMLS, the real mark should include pressure steel pipe factory name or trademark, and the material level, specifications, standards, wall number, batch number, pressure test (if any), NDE detection (if any)
Q:How to make the steel pipe spray paint is not easy to fall off?
First you will rust steel, to clean, good quality alkyd rustproof paint, completely dry after brushing paint, color to see his kind of love.
Q:Galvanized steel pipe in addition to good rust resistance, what are the advantages?
Galvanized steel is cracking for 39 days and will not, especially suitable for Northern very cold environment.
