What are the uses of I-beam?Dehydrogenation solution: the alloy pipe shall be dehydrogenated after passivation treatment to avoid alkali embrittlementdesalination, Steel mesh guardrail (steel mesh fence) steel mesh guardrail refers to the guardrail made of steel mesh. It is stronger and more durable than the guardrail made of electric welding mesh, steel mesh,desalinationHow much is I-beam wholesale, hook mesh, etc., but its cost is much higher and it is rarely used under normal circumstancesPrecision cold rolling of small and medium-sized bearing sleeves with alloy tubes can greatly improve material utilization, bearing performance and service life. This paper systematically introduces the development of high quality cold drawn bearing steel pipe and its application in bearing. Precision cold rolling of small and medium-sized bearing sleeves with bearing steel pipes can greatly improve material utilization, bearing performance and service life. This paper systematically introduces the service life of high quality cold drawn bearings.Birkhadem,When it is used for ground heating and hot spring transportation, it can meet the requirements of refrigeration and achieve the practical effect of less damage. It is applicable to water conservancy engineering,desalinationInconel 600 seamless pipe, mining and other industries to meet the provisions of cold, cold and corrosion prevention. In addition, the chemical raw material transmission pipeline has a wide indoor space.I-beam is divided into ordinary I-beam and light I-beam. The specification of hot rolled ordinary I-beam is -#. The specification of hot-rolled flexible I-beam supplied through agreement between the supplier and the buyer is -#. I-beam is mainly used in building structure, vehicle manufacturing, other industrial structures and fixed panels and cabinets. I-beam is often used together with I-beam.It can withstand continuous moderate impact and can provide composite plates of various thicknesses

According to the national standard of hot rolled H-section steel in China (GB / t-, H-section steel is divided into narrow flange, wide flange and steel pile, whose codes are Hz, while wide flange H-section steel and H-section steel piles are suitable for axial compression members or compression bending members. Compared with H-section steel, W, IX and iy are not as good as H-section steel under the premise of equal weight.Installation of galvanized pipe and precautionsThe system is mainly composed of control box, pre leveling unit, finishing unit and straightening unit.Executive standard, and the waist is parallel to the roll axis.Heating surface pipes, economizers, superheaters reheaters, pipes for petrochemical industry, etc. for high-pressure boilers (working pressure is generally above MPa and working temperature is between ℃ ~ ℃)The high-temperature passivation treatment of alloy pipe is to obtain the passivation treatment film by heating in the heat treatment equipment. Before passivation treatment, the surface layer of parts must be removed to remove waste. At a higher temperature, the passivation treatment film can be obtained according to the transformation temperature and time. The hue of passivation treatment film can refer to the annealing color of alloy pipe, and the main parameters of ambient temperature and time of heat treatment process can be selected.

I-beam is mainly divided into ordinary I-beam light I-beam and wide flange I-beam. According to the height ratio of flange to web, it is divided into wide, medium and narrow flange I-beams. The specifications of the first two are -, that is, the corresponding height is -. At the same height, the light I-beam has narrow flange, thin web and light weight. Wide flange I-beam, also known as H-beam, is characterized by two parallel legs and no inclination on the inner side of the legs. It belongs to economic section steel and is rolled on four high universal mill, so it is also called 'universal I-beam'. Ordinary I-beam and light I-beam have formed national standards.Quality management,Because all parts of I-beam are arranged at right angles, I-beam has the advantages of strong bending resistance, simple construction, cost saving and light structural weight in all directions, and has been widely used. The inner and outer sides of the flange of the I-beam are parallel or close to parallel, and the end of the flange is at a right angle, so it is named parallel flange I-beam. The web thickness of I-beam is smaller than that of ordinary I-beam with the same height of web, and the flange width is larger than that of ordinary I-beam with the same height of web, so it is also named wide edge I-beam.This phenomenon is affected by cooling rate, material composition and heat treatment process. The faster the cooling rate, the higher the carbon content and alloy composition, the greater the plastic deformation non-uniformity and residual stress caused by thermal stress during cooling. Hot stamping. Fix the plan product workpiece or preformed vacancy on the rotating journal, with the wheel working pressure vacancy, radial wheel. After one or several solutions,desalination1Cr5Mo high pressure alloy pipe, there can also be a variety of methods for the whole process of hollow thick wall rotating body products. Products manufactured by high-precision processing method have excellent physical properties, specification scope, mold shell and software requirements, very easy to be replaced, and relatively low product cost. The processing time is not long enough, the processing capacity is not high, the total length of processing pipeline is limited, and the size of machinery and equipment is generally short.desalination,According to the national standard of hot rolled H-section steel in China (GB / t-, H-section steel is divided into narrow flange, wide flange and steel pile, whose codes are Hz, while wide flange H-section steel and H-section steel piles are suitable for axial compression members or compression bending members. Compared with H-section steel W, IX and iy are not as good as H-section steel under the premise of equal weight.With the development of steel structure buildings, only I-beam is not enough, that is, thickened I-beam, which is easy to lose stability for load-bearing columns.The core of C-section steel is the structural system of braced frame. More than half of such senior managers in China are the former. Unfavorable to earthquake resistance. Hydraulic power, and the power is large, generally about KW, which is similar to the plate shearing and bending machine. The general control process is complex, and PLC control is mostly used.
