  How does the valve work?

  By definition, a valve is a device that controls the flow of fluids.Specifically, it is a mechanical device designed to direct, start, stop, mix or regulate the flow, pressure or temperature of a process fluid. The "fluid" handled by the valve may be air, water, steam, corrosive chemicals, mud, oil, gas, liquid metal, powder, slag or other dry materials, etc. By driving its closing member to move up and down, slide, rotate or swing, the valve can change its flow area to control the flow of fluids.

  Major Types of Cast Iron Pipes in Detail

  The essence of a cast iron pipe is a ductile iron pipe. Since the ductile iron pipe has the properties of iron and the performance of steel, it is called a ductile iron pipe. The graphite in the ductile iron pipe is spherical, and the size of the graphite is 6-7. In terms of quality, the spheroidization level of the cast iron pipe is required to be controlled at level 1-3, and the spheroidization rate is ≥80%. Therefore, the mechanical properties of the material itself are well improved, with the properties of iron and the performance of steel. The metallographic structure of the ductile iron pipe after annealing is ferrite and a small amount of pearlite. It has good mechanical properties, so it is also called a cast iron pipe.

  SSAW Steel Pipe Specification Size Chart

  SSAW steel pipe for steel casing is a spiral seam steel pipe made of strip steel coil as raw material, extruded at room temperature, and welded by automatic double-wire double-sided submerged arc welding process. The spiral steel pipe sends the strip steel into the welding pipe unit, and after multiple roller rolling, the strip steel gradually rolls up to form a round tube blank with an open gap. The pressing amount of the extrusion roller is adjusted to control the weld gap to 1~3mm, and the two ends of the weld are flush.

  Advantages and Performance of Hot-Dip Galvanized Square Tubes

  The production and application of galvanized square tubes have gradually established corresponding methods after many years of social experience. Cold-dip galvanized tubes have gradually withdrawn from the stage of application due to product shortcomings. Hot-dip galvanized steel pipes are made by reacting molten metal with iron substrate to form an aluminum alloy layer, so that the substrate and the coating are closely bonded. Hot-dip galvanizing is to first pickle and passivate the square steel pipe. In order to remove the impurities on the surface of the square steel pipe, after pickling and passivation, it is cleaned in an ammonium chloride or magnesium chloride solution or a mixed solution of ammonium chloride and magnesium chloride, and then sent to the hot-dip galvanizing tank. Hot-dip galvanizing has the advantages of uniform coating, strong adhesion and long service life.
