Q:What is the difference between hot dip galvanized steel pipe and galvanized steel pipe?
The difference between the process is that the hot dip galvanized pipe is dipped in the molten zinc bath and the galvanized pipe is plated with a metallic surface by means of unidirectional current in the plating bath. Hot plating process is fast, the coating is thick and consumes more zinc. Ordinary galvanized slow speed, thin coating.
Q:The difference between carbon and welded steel tubes
Seamless steel pipe because there is no weld, so can withstand greater pressure, boiler tubes are generally used seamless steel pipe
Q:Where is the difference between seamless steel pipe and welded pipe
Seamless steel tube is formed during rolling. Welded steel pipes need to be welded after coiling, and spiral welding and direct welding are generally used. Seamless performance is better, of course, the price is higher.
Q:Is the steel frame on each floor supporting formwork (floor) called full scaffolding?
The use of scaffold as its height, when the ceiling height below 3.6M, no matter what the ceiling decoration, decorative scaffolding are calculated
Q:What is the process of spiral steel tube production?
Butt welding: the use of advanced double submerged arc welding technology for pre welding, internal welding, external welding. The welded steel tubes are cut into standard lengths using a plasma gage.
Q:What is a tight steel tube?
The fully enclosed steel tube is called "sleeve connection steel pipe". The English abbreviation is JDG. The sleeve between the pipe and the pipe is fastened by screws. The current specification is the construction and acceptance rules of CECS 120:2007 sleeve steel conduit pipe line
Q:How much is the tube?
The first prerequisite we need to determine is: what are the specifications of the steel pipe mentioned? Such as the commonly used steel pipe specifications: diameter 108*4.5, diameter 219*6, diameter 377*10, diameter and wall thickness of steel pipe with different specifications, different weight, so the steel price per meter is different.
Q:Difference and application of seamless hot rolled pipe and cold drawn pipe in seamless steel tube
purpose2.1 seamless tubes are widely used. General purpose seamless tubes are rolled from plain carbon structural steel, low-alloy structural steel or alloy structural steel, with the most output and are used primarily as pipes or structural parts for conveying fluids2.2, divided into three kinds according to the supply of different uses: the supply of a, according to the chemical composition and mechanical properties; the supply of B, according to the mechanical properties; the supply of C, according to the hydraulic pressure test. According to a, the B class steel supply, such as for under fluid pressure, but also to the pressure test.2.3. Seamless tubes for special purposes include seamless tubes for boilers, seamless tubes for geology, and seamless pipes for petroleum use
Q:Where is a steel pipe casing usually used?
A straight tube of carbon steel sheathed on pipes and tubes and threading tubes to protect the joints from damage by electric welding. The purpose is to protect the wires and cables.
Q:Why seamless steel pipe called seamless steel pipe?
Seamless is relative to welded steel pipe, because welded steel pipe is welded with steel strip, seamless steel pipe is made of whole round steel empty, no welding seam.
