Product Description:

1Structure of Hollow Section Steel Pipe Various Size: 

The square tubes are used in structural projects, shelves, racks, trailers and in ornamental purpose. The framework made by square steel tubes, is used for providing support to the roof. This framework is also used as roof top ventilation baffles. With compare to round steel tubes, square steel tubes are little more efficient. To be used for construction, furniture structures as well as other fabrication purposes. It is widely used in building, machine, chemical equipment, automobile industrial, container, it is also applied to agriculture and mine machine.

Q:Are the welded and galvanized tubes the same weight?
There should be no difference in the weight of the same specifications for the welded pipe and galvanized pipe. The slight difference is that the galvanized pipe should be pickled before galvanizing and must digest some iron and then galvanized. The difference depends on the difference in the process. So the theoretical calculations are the same.
Q:What's the difference between the fastener type steel pipe scaffold, the floor type steel pipe scaffold and the overhanging type steel pipe scaffold?
Butt fastener: used for connecting two steel pipe joints.The base and the pad: is set up in the bottom of the pedestal pole, pay attention to the distinction between base and the base plate, usually with steel plate and welded steel pipe, base usually put on a backing plate, and the plate can be wood can also be plate.The foot board (see the diagram below), safety net (no explanation, this is very simple).
Q:What is the meaning of "DN" and "Phi" in the dimensioning of steel pipe diameter and how to apply the mark?
DN refers to the nominal diameter of the pipe, but this is neither the outside diameter nor the inside diameter, and the "Phi" means the outer diameter of the steel pipe. For example, the same nominal diameter of the steel pipe due to its different wall thickness, corresponding to the outer diameter is also different. As can be seen from the chart below:Project control table (commonly used) diameter pressure pipe standard pressure pipe standard pressure pipe standard specification DN- nominal diameter: diameter of large diameter series DN15- 22mm DN20- 27mm DN25- phi, Phi Phi Phi Phi 34mm, DN32- 42mm DN40- 48mm DN50- 60mm DN65-, Phi Phi 76 (73) mm, DN80- 89mm DN100- 114mm DN125- and Phi Phi Phi. 140mm DN150- 168mm DN200- 219mm DN250- phi, Phi Phi Phi Phi 273mm, DN300- 324mm DN350- 360mm DN400- 406mm DN450- 457mm DN500- and Phi Phi Phi Phi, 508mm DN600- 610mm, DN15- 18mm series of small diameter Phi Phi Phi, DN20- 25mm DN25- 32mm DN32- 38mm DN40- 45mm DN50- Phi Phi, Phi Phi Phi 57mm DN65- 73mm, DN80- 89mm DN100- 108mm, DN125- 133mm DN150- 159mm DN200- and Phi Phi Phi Phi, 219mm DN250- 273mm DN300- 325mm DN350- 377mm, Phi phi,
Q:Can galvanized steel tubes simmer?
Galvanized steel pipe can simmer bending.Is a set of bending bending bending die, no matter what kind of equipment, most are used in pipe, mainly used for oil and gas, infusion, more plays an important role in aircraft and engine.
Q:What time what time for gas pipeline steel pipe PE pipe
PE pipe must be installed underground, the steel tube can be exposed, when not all PE pipe for pipe laying, overhead installation. But the steel tube is easy to rust, so it can be used where the basic use of PE pipe buried PE pipe.There are galvanized steel pipe and seamless steel pipe, galvanized pipe can only be used for low-pressure homes
Q:What quota is reserved for buried DN20 steel pipe?
If it is reserved for embedded pipe pre buried steel waterproof casing, set of waterproof casing steel production and installation is to set the quota items, if the outdoor installation of welded steel pipe buried steel casing pre quota items, if it is a reserved hole, then there is no need to set the quota items.
Q:How to establish a concrete-filled steel tubular column model in ANSYS?
First, you have to choose at least three or more types of materials. Modeling is a little complicated. Strongly recommended that the landlord to see "ANSYS in civil engineering applications", where there is such an example, you step by step, step by step back, and then in accordance with their own requirements modeling, OK. Wish you success
Q:What's wrong with the 3PP anticorrosive steel tube?
PP and PE are similar in processability, and the 3PE coating can be used to produce 3PP coatings without the need for a special 3PP coating line. However, the difference between PP and PE materials makes the 3PP and 3PE coatings show different properties, which can be applied to different environments. The advantages of 3PP coating on some properties make it possible to play an important role in the field of 3PE coating. Therefore, many foreign pipeline projects use 3PP anticorrosive coating.
Q:20# seamless steel pipe and seamless steel pipe 20G what is the difference?
20#: low carbon steel seamless steel pipe, carbon steel is generally divided into low carbon steel, medium carbon steel and high carbon steel three, 45# steel in carbon steel, low carbon steel is lower than 45#, 45# is higher than that of high carbon steel, seamless steel pipe, such as no special requirements, using 20# seamless steel tube. 20# seamless steel pipe material is 20# steel, the strength is slightly higher than 15#, very little quenching, no temper brittleness. Cold plastic deformation and for bending, rolling, bending and hammer arch processing, arc welding and contact welding welding performance is good, when the thickness is small, prone to strict requirement of shape crack or complex shape parts. The cold or normalizing state of the cutting process is better than that of the annealed one. It is generally used to make workpieces with little stress and high toughness.
Q:45 and 316 which steel tubes are of high hardness?
This depends on the heat treatment state, if 45 steel, 314 stainless steel without heat treatment, 316 stainless steel hardness, if the heat treatment, that is 45 steel hardness.
