Q:25 of the steel pipe with 6 in charge of what is the difference?
Outer diameter representation of steel pipe:When the design is nominal diameter DN means diameter, should be nominal diameter DN and the corresponding product specifications table. Specification for unplasticized polyvinyl chloride pipes for building drainage, de (nominal outer diameter) * e (nominal wall thickness), (GB, 5836.1-92), polypropylene (PP) pipe for water supply, specifications by de * e (nominal outer diameter * wall thickness).
Q:What is PE coated steel pipe? Seek explanation
PE pipe is a kind of thermoplastic resin with high crystallinity and non polarity.
Q:Why can't stainless steel be put together with carbon steel tube?
1, the potential difference is: potential "stainless steel tube" and the negative potential "carbon steel" coupled "stainless steel", "a cathode carbon steel tube" is anode potentials of the two difference the greater the galvanic corrosion is bigger.2. An electronic passage formed by wire connection or direct contact. The carbon in the carbon steel tube loses its electrons to the stainless steel tube and the surface is absorbed by the etchant.3. Electrolyte: the contact area of two metals is covered or submerged by electrolyte. The iron in the carbon tube loses electrons to form ions into the solution, and the electrons on the surface of the stainless steel tubes are taken away by the corrosive agents in the electrolyte (such as oxygen in the air). Electrolytes become ionic channels.
Q:How much is the wall thickness standard of building 48?
Steel tube (Steel pipe) production technology development began in the bicycle manufacturing industry, the rise of the early nineteenth Century during the oil development, the two world war ships, boilers, aircraft manufacturing, manufacturing of power boiler after the Second World War, the development of chemical industry of petroleum and natural gas drilling and transportation, will effectively promote the the yield and quality of varieties, the development of steel tube industry.
Q:What is DN50 for welded pipe?
Commonly used in the market DN50 seamless steel pipe, the outer diameter has two specifications: A, 57mm, B, 60mm, if no special instructions, commonly used is 57mm. The outer diameter of the welded pipe is only 60mm this specification.
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:DN80 seamless steel tube, what is the standard thickness?
The DN80 specification is 89*6 seamless steel management formula = (outside diameter wall thickness) * wall thickness *0.02466= per meter weight
Q:What are the main types of steel pipe ah? How to judge which kind of steel pipe performance is better?
Steel pipe according to the production method can be divided into two categories: seamless steel pipe and pipe joints, pipe joints as welded steel pipe.1. seamless steel tube according to the production methods can be divided into: hot-rolled seamless pipe, cold drawn tube, precision steel tube, heat expansion tube, cold spinning tube and extrusion tube.Seamless steel tubes are made of high quality carbon or alloy steel. They are hot-rolled and cold-rolled (drawn).Bundled steel pipe
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:Seamless steel pipe 8162 and 8163 what is the difference?
8163 GB is fluid delivery tube, need to use eddy current detection, fluid transport, liquid, gas, solid, such as natural gas, water, gas, coal and stone, 8162 and 8163 of the popular point that is 8163 more than 8162 senior, 8163 inspection, 8162 inspection. I hope you understand!
