Q:Material of welded steel pipe
GB/T3091-1993 (galvanized steel pipe for low pressure fluid delivery). Mainly used to transport water, gas, air, oil and heating, hot water or steam, etc. generally lower pressure fluid and other use tube. Its representative material is Q235 grade a steel.
Q:The outer circle of a seamless steel pipe 50 head into the outer circle of the 40 to close
That is, according to the production process of different classification, different from hot rolling (expansion) pipe. In the process of expanding the tube or raw material tube, it is processed by multiple cold drawing, usually on single chain or double chain cold drawn machine of 0.5 ~ 100T. Cold rolled steel pipe (DIAL) in general, steel pipe for low and medium pressure boiler tube, high-pressure boiler steel pipe, alloy steel pipe, stainless steel pipe, oil cracking tube, machining pipe, thick wall pipe, small diameter and cold drawn steel tube also includes other tubes, carbon thin-walled steel, alloy thin-walled steel pipe, stainless steel pipe, special-shaped wall steel pipe. The outside diameter of cold drawn steel tube wall thickness to 6mm, to 0.25mm, to 5mm diameter thin-walled tube wall thickness is less than 0.25mm in size, accuracy and surface quality were significantly better than the hot (expanding) tube, but by the process control, its diameter and length are limited.
Q:Which is more load-bearing, the same thickness of steel pipe and steel bar?
The same length, the same pipe diameter, the same material strength is hollow, the ratio of area of steel (solid), and the cyclical and slender radius smaller than the larger, so the longitudinal stability coefficient is smaller, three factors, two factors are weak in steel reinforced, another factor: strength, they are the same, no doubt, steel reinforced bearing less than.
Q:What is the meaning of "DN" and "Phi" in the dimensioning of steel pipe diameter and how to apply the mark?
DN is a kind of Engineering path, not the actual value, due to the different standards, so the actual corresponding values is not the same; phi is refers to the actual value, the same national standard pipe inside the steel pipe, the actual value is the same, for example, GB/T8163 and GB GB fluid pipe spiral pipe and GBT/T9711.1 GB/T12459 the same nominal diameter corresponding to the actual value is the same as the actual value; and American Standard steel standard ANSI B 16.38 and ANSI B 16.9 standard American Standard fitting the same nominal correspondence is the same. If marked, the nominal diameter should be added DN, and the actual value can be omitted.
Q:What are the uses of welded steel pipes?
Ordinary carbon steel wire bushings (GB3640-88) are industrial and civil construction, installation of machinery, equipment and other electrical installation works for the protection of electric wire.
Q:304 stainless steel tube with the diameter of 25*2-3 is what mean
This is according to the "water drawing standards" (GBT50106-2001) in 2.4.2-2 seamless steel pipe, welded steel pipe (straight or spiral seam), brass, stainless steel pipe, pipe diameter should be D diameter * thickness representation (such as D108 * 4 and D159 * 4.5); and the provisions of the habit of acting D with seamless pipe diameter.
Q:How can seamless steel tubes be produced?
Seamless steel tubes are made of ingots or billets made by piercing and are then made by hot rolling, cold rolling or cold casting. Seamless steel tube plays an important role in the steel tube industry of our country. According to incomplete statistics, China's existing seamless tube production enterprises about more than 240, seamless steel pipe units about more than 250 units, with an annual output capacity of about about 4500000 tons. From the caliber, 35% of phi 76, less than phi 159-650, accounting for 25%. From the species point of view, the general use of 1 million 900 thousand tons of pipe, accounting for 54%; oil pipe 760 thousand tons, accounting for 5.7%; hydraulic props, precision pipe 150 thousand tons, accounting for 4.3%; stainless steel pipe, bearing tube, automobile tube 50 thousand tons, accounting for 1.4%.
Q:Seamed steel pipe seamless steel pipe, carbon steel pipe, galvanized pipe, four how to distinguish between
Welded and seamless steel pipe is divided according to the processing form, usually welded seam steel tube, seamless steel tube drawing and hot two ways, carbon steel is material, galvanized pipe is welded pipe production after the surface is galvanized
Q:What materials are used in scaffolding pipes?
Using 48.3 * 3.6mm steel pipe, the maximum thickness of the steel pipe shall not be less than 3.24mm (there should be no serious corrosion, bending, flattening or crack); the corrosion depth of the old steel pipe shall be in accordance with the construction fastener typeProvisions on the safety technical specification for steel pipe scaffold JGJ130-2011. Take three of the corroded steel tubes, and cut the samples at the most severe parts of the rust. The corrosion depth shall not exceed the prescribed valueUse。 In addition, the approach of the steel pipe should also be sampling retest, qualified before use.
Q:What's the difference between round and round tubes?
Round steel is generally refers to steel, the surface is not threaded, different from round steel pipe, round tube is round tube.
Currently, the company can take the single and double pipe fusion bonded epoxy powder corrosion (FBE), double-layer polyethylene (2PE) and three-layer polyethylene anti-corrosion (3PE), double layer polypropylene anti-corrosion (2PP), and three-layer polypropylene (3PP) outer coating works. Executive DIN30670, DIN30671, SY/T0413-2002, SY/T0315-97, GB/T23257-2009 standard, corrosion range φ34-φ1600mm, the annual production capacity of 200 million square meters.
