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:What type of steel pipe dance is used in general?
The steel pipe fittings used in the pipe dance are made of smooth surface material, usually chrome or polished by steel or iron.
Q:Which is better, galvanized steel pipe or stainless steel?
Most of the use requirements are to maintain the original appearance of the building for a long time. In determining the type of stainless steel to be chosen, the main consideration is the aesthetic standards required, the corrosivity of the atmosphere in the area, and the cleaning system to be adopted. However, other applications increasingly seek only structural integrity or watertightness. For example, the roof and side walls of industrial buildings. In these applications, the construction cost of the owner may be more important than the aesthetic, the surface is not very clean can also. The use of 304 stainless steel in a dry indoor environment is quite effective.
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: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?
The outer steel tube diameter is 48mm, the tube wall thickness is 3mm, the theoretical weight per meter is 3.3291kgCalculation formula: (outside diameter wall thickness) * wall thickness *0.02466(48-3) *3*0.02466=3.3291kg
Q:Why can't stainless steel be put together with carbon steel tube?
The bimetallic corrosion is terminated only when one of the three conditions is changed. Galvanic corrosion is related to the contact area of bimetal and the greater the contact area. Corrosion is less. The driving force of galvanic corrosion is the potential difference.[galvanic corrosion] refers to two or more than two kinds of electrode potential of metal in the corrosive medium, and contact with each other caused by electrochemical corrosion, also known as contact corrosion or double metal corrosion.
Q:Are metal spiral tubes the same as metal bellows?
The spiral tube called spiral steel tube or spiral welded pipe, the low carbon steel or low alloy structural steel strips in a helical line certain angle (called forming angle) rolled into a tube, then the tube welding seam made up, it can be used in narrow strip production of large diameter steel pipe. The pitch of a spiral pipe is much larger than that of a bellows.
Q:What do you mean by "SC" in welded pipe SC200? What's the diameter of 200?
SC in principle, it should be called water gas pipe, also called thick wall steel pipe;
Q:How big is the seamless steel tube of DN50?
Domestic steel pipe diameter is generally divided into A series and B series, DN50 pipe diameter of 60mm and 57mm respectively, the wall thickness should be based on your design pressure, temperature, pipe material to calculate.
Q:Where is the difference between seamless steel pipe and welded pipe
Seamless pipe pressure is higher, welded pipe is generally in 10 or so MPa, now welded pipe to do seamless processing.
Q:Who knows what is the difference between double submerged arc welded pipe and longitudinal submerged arc welding?
Double submerged arc welding should be for spot welding and single side welding, they are straight line welds, but double submerged arc welding seam is more beautiful and fine.
