Product Description:

1Structure of  Galvanized welded steel pipe for materials :

The surface of galvanized steel pipe welded steel pipe of hot dip galvanized layer or. Galvanized can increase the corrosion resistance of the steel tube, prolong service life. Galvanized pipe is widely used, in addition to water, gas, oil and other general low pressure fluid pipelines. It is also used in the petroleum industry, especially for offshore oil field of oil well pipe and oil pipe, chemical, coking equipment of oil heater, condensation cooler, coal run oil exchanger tube, and trestle pile, the mine tunnel support frame tube.

Q:What's the difference between hot dip galvanizing and cold galvanizing? Which kind of galvanizing method is good?
Cold galvanizing is zinc plating, the general surface is relatively smooth, no zinc flowers, there are two kinds of resistance to fingerprints and non - Fingerprint
Q:What is PE coated steel pipe? Seek explanation
PE pipe is a kind of thermoplastic resin with high crystallinity and non polarity.
Q:What is the difference between steel pipe and round steel?
The middle of the steel pipe is hollow, and the round steel is solid. When compared with the solid steel such as round steel, the steel tube has the same flexural strength and torsion strengthLight weight, is an economic section of steel, widely used in the manufacture of structural and mechanical parts, such as oil drilling pipe, automobile transmission shaft, bicycle frame and steel scaffolding used in construction.
Q:What's the gate number of the precision steel pipe?
This kind of steel tube and ordinary hot-rolled seamless steel pipe and cold drawn seamless steel tube in the outer surface is different from the outer surface, and the diameter of the smooth finish of precision steel tube, stainless steel color and the same, inside and outside surface due to manufacturing reasons with a layer of oil.
Q:Why can't stainless steel be put together with carbon steel tube?
Stainless steel can not be put together with carbon steel because of galvanic corrosion
Q:How much is the wall thickness standard of building 48?
According to the "construction of fastener type steel pipe scaffold safety technical specifications JGJ130-2011" stipulates that the specification of steel pipe should be Phi 48.3 * 3.6, that is, wall thickness is 3.6mm.
Q:What is lined pipe?
Pipe lining is a new technology in recent ten years of development, also called composite pipe conveying fluid with different needs, the use of different materials to make the durability of the pipeline inner wall and outer wall of pipeline, to ensure the purity of the fluid, pipeline adaptability, performance is greatly improved, more extensive use.
Q:Why should the weak electricity be pre buried with galvanized steel pipe?
Galvanized steel pipe mainly because of anti-interference and electrical connectivity, to prevent other strong magnetic strong signal to interfere with weak signal, while in the electrical connection, galvanized steel pipe can be directly connected to the bridge.
Q:Galvanized steel pipe DN100 and SC100
Zinc plating, hot dip galvanizing and cold galvanizing, to see the design instructions and design requirements, which will explain
Q:What is the outer diameter of the steel tube?
The outer diameter refers to the maximum diameter including the thickness of the steel tube, the inner diameter is the length of the hollow part inside, and the outer diameter minus the inside diameter is the thickness of the steel pipe
