Q:What does "SC50" steel pipe mean in civil engineering?
The corrosion resistance of Ni is very strong in acidic environment. In the environment containing sulfuric acid or hydrochloric acid, the higher the content of Ni in the welded pipe is, the stronger corrosion resistance is. In general circumstances, the addition of Cr in a T-junction steel pipe prevents erosion. The marginal condition of the steel strip is another important cause of the wrong edges. The influence of mass flow rate, heat flux density and structural parameters (ratio of spiral curvature diameter and diameter of T-shape welded tube Dc/D) on heat transfer coefficient of saturated bubble boiling in vertical helical tubes.
Q:How to perform nondestructive inspection of steel tubes
Including fluorescence, coloring two kinds. Because of its simple equipment and convenient operation, it is an effective method to check the surface defect of magnetic particle inspection. It is mainly used for surface defect inspection of non-magnetic materials.
Q:Is the steel frame on each floor supporting formwork (floor) called full scaffolding?
The scaffold is also called full house scaffolding is a construction process for building a scaffold. Hall scaffolding relative to other scaffolding system density, that is, the house full of shelves. The full scaffolding is more secure than the rest of the scaffolding.
Q:The plastic pipe and steel pipe difference
In the plastic coated galvanized steel pipe inside the plastic coated manufacturing method. The thickness of the internal plastic is thin, which is equal to a plastic skin.
Q:What is PE coated steel pipe? Seek explanation
The appearance of the native HDPE is milky white and is somewhat translucent in the narrow cross section. PE has excellent properties that are resistant to most life and industrial chemicals. Polyethylene (PE) pipe due to its unique advantages and is widely used in building water supply, drainage, underground drainage pipe, building heating, gas pipelines, electrical and telecommunications, industrial protective casing pipes, agricultural pipes etc.. The utility model is mainly used for urban water supply, urban gas supply and farmland irrigation.
Q:Is there any difference between HFW steel pipe and ERW steel pipe?
Resistance welding, as the name suggests, resistance welding is a method of welding by welding electrode after exerting pressure on electrode and utilizing electric current through the contact surface of connector and adjacent zone. High frequency welding: high frequency current through the metal conductor, will produce two kinds of peculiar effects: skin and proximity effects, high frequency welding is the use of these two kinds of effects of steel pipe welding, the effects of the two is based on the high frequency welding metal.
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:Fastener type steel pipe scaffold external parts name
Fastener type steel pipe scaffold fastener malleable iron casting should be adopted, its basic form has three kinds: vertical cross bar for a connection between the rectangular fastener, fastener for rotating connecting parallel or oblique bars and rods for butt joint butt joint fastener.
Q:Galvanized steel pipe in addition to good rust resistance, what are the advantages?
It has the characteristics of corrosion resistance and wear resistance, so it can be used longer;
Q:What are low-pressure carbon steel tubes?
Any of various steels that contain less than 2.11% of the mass of carbon but contain no alloying elements. Sometimes referred to as plain carbon steel or carbon steel.Carbon steel, in addition to carbon, usually contains a small amount of silicon, manganese, sulfur and phosphorus.1) according to the use of carbon steel can be divided into carbon structural steel, carbon tool steel and easy to cut structural steel three categories, carbon structural steel is divided into engineering construction steel and machine manufacturing structural steel two kinds;(2) by refining methods can be divided into open hearth steel, converter steel;(3) according to deoxidization methods, they can be divided into boiling steel (F), killed steel (Z), semi killed steel (b) and special killed steel (TZ);(4) according to the carbon content of the steel can be divided into low carbon steel (WC = 0.25%), carbon steel (WC0.25% - 0.6%) and high carbon steel (WC>0.6%);(5) according to the quality of steel, carbon steel can be divided into ordinary carbon steel (phosphorus, sulfur, higher), high quality carbon steel (low phosphorus and sulfur) and high quality steel (lower phosphorus and sulfur) and super quality steel.Description: the carbon content in general carbon steel is higher, the hardness is higher, the strength is higher, but the plasticity is lower.
After more than a decade’s construction and development, we have taken a leading position in seamless steel tube industry in China. In the year 2007, it awarded Famous-brand product Certificate. Besides, we have been named as excellent supplier of Qualified Products by our customers for several times.
