Q:What is the outer diameter and wall thickness of DN40 steel pipe?
DN40 pipe diameter 48.3mm diameter, allowable deviation of plus or minus 0.5mm it depends on what you have, the outside diameter of 45, there are other dimensions, you can see the manual
Q:How to distinguish seamless pipe and welded pipe?
If there is a weld seam in the fracture surface, whether it is inside or outside the pipe, then it is the welded pipe
Q:What is the difference between the stainless steel pipe welded pipe and seamless pipe?
Seamless tube is a strip of steel with a hollow cross section and no seams at all. The general is rolled into a cylindrical tube plate welding.
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:Does seamless steel tube have a bend of 135 degrees?
In engineering, it is usually marked as "45 elbow" and has no "135" mark. The angle of the elbow is acute, so there will be no more than 90 degrees elbow.Elbow is a common connecting pipe used in plumbing and heating. It is used for the connection of the bend of pipe, and is used to change the direction of pipe.
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: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.
Q:Is it good to buy a simple wardrobe or a steel pipe?
If the home place is big, buy Wooden, good-looking durable, if the place is small, buy cloth, easy to receive, mobile, tidy and cheap.
Q:Can seamless steel pipe and ordinary steel pipe be welded?
Steel pipe and seamless linking points, you said should refers to ordinary steel pipe joints, if only consider the butt welding problem, two kinds of steel can be welded. But the mechanical properties of the seamless steel pipe and tube with different, generally the main difference is the two kinds of steel can withstand the pressure of the former than the latter to be good.So if your project is seamed steel pipe can be, then the two pipe welding, welding and butt welding interface is completely no problem.
Q:What's the difference between a cracked carbon steel tube and a liquid carbon steel tube?
If the material is the same, the process is different from the test.
