Hot-plunge electrifies steel channels are generally utilized in development, apparatus, coal, substance, electric power, railroad vehicles, car industry, expressways, spans, holders, sports offices, horticultural hardware, oil hardware, mining apparatus and other assembling ventures in galvannealed steel sheet suppliers.
Electrifies steel channels are welded with hot-plunge or aroused steel. Zinc plating can build the erosion opposition of steel pipes and draw out their administration life. Excited channels are broadly utilized, notwithstanding pipelines for general low-weight liquids, for example, water, gas, oil, and so forth., and furthermore utilized as oil well pipes and oil pipes in the oil business, particularly in seaward oil fields, and oil radiators and buildup of compound coking gear. Cooler, coal distillate oil exchanger pipe, and trestle pipe heap, bolster pipe for mine passage, and so on.
The hot-plunge stirred cylinder is gotten by responding a liquid metal with an iron lattice to deliver a compound layer, consequently consolidating the substrate and the plating layer. Hot-plunge stirring is to pickle the steel pipe first, so as to expel the iron oxide on the outside of the steel pipe, in the wake of pickling, it is washed by ammonium chloride or zinc chloride watery arrangement or a blended fluid arrangement of ammonium chloride and zinc chloride, and after that bolstered. Hot plunge plating tank. Hot-plunge exciting has the benefits of uniform plating, solid attachment and long administration life.
The electrifies pipe and the liquid plating arrangement experience complex physical and substance responses to shape a consumption safe structure of a zinc-iron amalgam layer. The combination layer is incorporated with the unadulterated zinc layer and the steel pipe base, so it has solid consumption obstruction.
The cold-electrifies pipe is electro-stirred, with a limited quantity of arousing, just 10-50g/m2, and its consumption obstruction is much more terrible than that of hot-plunge excited pipe. Customary aroused pipe makers, so as to guarantee quality, most don’t utilize electro-exciting (cold plating). Just little organizations with little hardware and old gear use electro-stirred steel, obviously, their costs are moderately less expensive. The Ministry of Construction has authoritatively set out the cold-stirred pipe with in reverse innovation and the utilization of cold-electrifies pipe as water and gas pipe.
The electrifies layer of the cold-stirred steel pipe is an electroplated layer, and the zinc layer and the steel pipe base are independently layered. The zinc layer is meager, and the zinc layer is essentially joined to the steel pipe base and is anything but difficult to tumble off. In this way, its consumption opposition is poor. In new homes, the utilization of cold-aroused steel pipes as water supply funnels is restricted.
