Steel Structures can be used in many industries such as foundation reinforce, electric power transmission structures and tubular scaffolding, etc.
A flange can also be a plate or ring to form a rim at the end of a pipe when fastened to the pipe. A blind flange is a plate for covering or closing the end of a pipe. A flange joint is a connection of pipes, where the connecting pieces have flanges by which the parts are bolted together.
Although the word flange generally refers to the actual raised rim or lip of a fitting, many flanged plumbing fittings are themselves known as 'flanges':
There are many different flange standards to be found worldwide. To allow easy functionality and interchangeability, these are designed to have standardised dimensions. Common world standards include ASA/ASME (USA), PN/DIN (European), BS10 (British/Australian), and JIS/KS (Japanese/Korean). In the USA, ANSI stopped publishing B16.5 in 1996, and the standard is ASME B16.5

Hot-dip galvanized fence nets are silver-white in color and have a long life span. They can be used in suburban areas for more than 50 years. In urban areas or offshore areas, the service life can reach 20 years.
1. Analysis of Causes for Low Efficiency of Galvanized Production of Fence Mesh According to the heating characteristics of the fencing mesh, it is necessary to have the open melt furnace to work. That is, the minimum height of the molten metal in the furnace must ensure that the sensing groove of the inductor can be submerged. Therefore, each time a good zinc alloy is prepared, only about 1/3 of the molten zinc can be cast (ie, the remaining metal level is guaranteed to be higher than the start-up melting height), and then zinc flakes must be added to melt and re-prepare the next furnace batch melting. When carrying out alloy preparation, mixing and pre-furnace analysis, Qi Long Fence Factory can only stop heating or keeping warm, the continuous melting advantage of the high-power induction furnace can not be achieved, and the mixer's lifting and lifting operations are troublesome.
2. For the galvanized alloy composition of the fence mesh, the alloy composition is not uniform. Because the diameter of the stirring blade is restricted by the aperture size on the top (influence of thermal efficiency), the influence of the small-scale stirring on the rectangular furnace is limited, so Qilong Network Insufficient agitation and the iron-enhancing effect of the blade have a negative effect on the uniformity of the components and on the requirements of the iron content. How to change the variety of fence mesh alloys troubles, need to replace the alloy varieties, Qi Long to large-capacity cored furnace washing furnace is a time-consuming and costly work, when changing alloying elements, the washing furnace takes a long time to complete the work . Has influence on the electrical appliances and furnace age. When the alloy fluid is released, a large amount of zinc flakes are added, the temperature is the lowest, and high power is required to raise the temperature; when the intermediate alloy is formulated, the temperature needs to be raised to the highest level, which is not favorable in terms of energy consumption and metal burn. control.
Hot-dip galvanized fence net has long use time, sturdiness and durability, saving time and effort, comprehensive protection, mainly used in highways, communities, airports, factories and mines, etc. More hot-dip galvanized fence fence is made in Hebei Qilong Fence Factory.
Hot dip galvanized fence mesh production process
Hot dip galvanized fencing production process---Hebei Qimi Fence Factory mainly produces hot-dip galvanized fencing mesh (hot-dip galvanized fencing mesh). It is a method of immersing fencing mesh in molten metal to obtain metal plating, and is coated with a fence. A metallurgically bonded alloy layer is formed between the net and the plated metal through dissolution, chemical reaction and diffusion.
