EstoniaLarge diameter 15CrMoG alloy pipeHas gradually become a mainstream product

After determining the reasonable pickling agent and polishing solution,EstoniaMONEL400 alloy pipe, it is very easy to carry out hot galvanizing for relevant alloy pipes. Use 'phosphating treatment' to degrease the pipes of electrolytic machine equipment, put them into the aqueous solution with zinc salt after pickling and passivation, connect the negative level of electrolytic machine equipment, put them into the cold-rolled steel plate in the direction corresponding to the pipes, and connect the switching power supply, If the current flows from the positive stage to the negative stage, a layer of zinc is deposited in the pipe.The delivery length of I-beam is divided into fixed length and double length and the allowable difference is specified in the corresponding standards. The length selection range of domestic I-beam is divided into -, - and - according to different specification numbers. The length selection range of imported I-beam is generally -.Estonia, The tensile strength of seamless pipe is more than ~ times that of ordinary steel, the elastic coefficient is better than that of steel, and has good creep resistance, and the macroeconomic orientation is vertical to the cold rolling orientation, showing a 'high mountain' shape.Beroroha,Application characteristics of I-beamThe finished product has smooth surface, low friction coefficient flatness error + / - mm / m length, wear resistance and maximum temperature of ℃I-beam features: the content of chromium carbon alloy is -%, the hardness of chromium carbide alloy is V, and the macro hardness is - HRC

I-beam, is a long strip of steel with I-shaped section. I-beam is divided into ordinary I-beam and light I-beam. It is a section steel with I-type section shape.When the beam width is small, the reinforcement shall be bent.It can withstand continuous moderate impact and can provide composite plates of various thicknessesWelcome calls ,Alloy tube is widely used in our daily life, which provides us with great assistance.It is often asked that the shape of I-beam is similar to that of H-beam. What is the difference between them? Many people can&#;t explain it in detail. Here is a detailed answer for you: many people think that I-beam is a domestic name and H-beam is a foreign name. In fact, this cognition is wrong. H-beam and I-beam are different in shape!I-beam can be divided into four types according to shape: cold-formed equal edge I-beam, cold-formed unequal edge I-beam, cold-formed inner crimping I-beam and cold-formed outer crimping I-beam.

a. In the forming process, the thick steel plate has uniform deformation, small internal stress and no scratch on the surface. The alloy pipe produced and processed has higher coordination ability in the scope of size,EstoniaHow much is a month for steel bar proofing, specification and model of diameter and wall thickness, especially in the production and manufacturing of steel structure design grade thick wall pipe, especially medium diameter small thick wall pipe, which has incomparable advantages of other processing technologies, and can meet a large number of customer regulations on the specification and model of alloy pipe.Work courses,After the passivation treatment of alloy pipe,EstoniaHow much is a dn70 galvanized pipe, it is clearly proposed that water cleaning shall be carried out immediately after the aqueous solution, ~ times of water cleaning, and then chromic acid closed solution shall be carried out. Chromic acid solution must be carried out h after the subsequent water cleaning of metallographic structure and austenitic alloy pipe. Chromic acid aqueous solution (mass ratio) is % ~ % the solution temperature is ~ ℃,It can withstand continuous moderate impact and can provide composite plates of various thicknessesSome applications of I-beam:Key technical characteristics of alloy pipe:
