Estol15CrMo thick wall alloy pipe, chromizing, boronizing, siliconizing and so on are commonly used in production.The general alloy pipe with improved performance is variable and has high application value. The alloy pipe contains more Cr and is heat resistant Low temperature resistance Corrosion resistance. There is no aluminum alloy in plain carbon seamless steel pipe, not very little aluminum alloy, and the alloy pipe is used in crude oil Aerospace Chemical plant Power engineering heating furnace. Because the physical properties of alloy tubes are easy to change and adjust.Estol,Are there many welded types of mesh produced? According to the welding type and overall improvement, the difference between the reinforcement mesh and the welded mesh is not particularly large. It is still due to the scattered quality of the southern city. From the perspective of development to the longitudinal and transverse interleaving devices of the reinforcement mesh, the bound or welded mesh has better application quality.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.Najin, Direct rolling pass system. The direct rolling pass system refers to the pass system in which the two open legs of the I-beam pass are on the same side of the roll axis at the same time, and the waist is parallel to the roll axis.H-shaped steel groove is deep and thick, and can withstand forces in two directions.Classification introduction

The pickling agent in the pickling process contains many acidic substances, including hydrochloric acid, which has strong corrosion and reduction, and the temperature of etching substances is relatively high. Therefore, the corrosion resistance of alloy pipes is specified higher. The zinc layer obtained by electroplating is relatively pure, which corrodes slowly in acid, alkali and other fog, and can effectively maintain the steel matrix;→ I-beam can be processed into T-beam, and honeycomb beam can be combined to form various section forms, which greatly meets the needs of engineering design and manufacturing.Where is it,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, 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, whether ordinary or light, can only be directly used for bending members or lattice members on its Web because of its large and narrow section size and large moment of inertia difference between the two main axes on the section. It is not suitable for axial compression members and flexural members perpendicular to the web plane, so its application range is very limited. I-beams are widely used in buildings and other metal structures.I-beam is mainly used in building structure, curtain wall engineering, mechanical equipment and vehicle manufacturing.

Direct rolling pass system. The direct rolling pass system refers to the pass system in which the two open legs of the I-beam pass are on the same side of the roll axis at the same time,It is widely used in various fields of national economic construction, such as buildings, bridges, power stations, oil drilling platforms,Estol16Mn thick wall welded pipe, vehicles, highways, subways, steel structure plants and large warehousesThe storage of galvanized pipes should pay attention to several points. The first is the storage location. It cannot be placed in the open air, because in the open air, not only the safety of various products such as theft, but also corrosion problems will occur. Open air sites are vulnerable to various extreme weather conditions. Large amounts of rain or snow will erode the zinc coating on the surface to the greatest extent, which may lead to rust of the product. The second is the details of storage. It is not directly exposed to the sun. It shall be cooled and dried and shall not be stored with corrosive articles. The small length of repair welding is mm; The raw material shall not exceed mm after grinding by welding edge.Estol,X-ray or ultrasonic testing shall be carried out for repair welding of alloy pipe, dead end welding of strip steel and circumferential seam. For the spiral welding of steel for the transportation of flammable general liquids,EstolHow much is welded pipe, yibai%sx ray or ultrasonic testing shall be carried out. For the spiral welding of alloy pipes for the transportation of water, wastewater, gas heating steam and other general liquids, the moment of inertia of the two main sleeves of the section is quite different X-ray or ultrasonic testing sampling inspection (%) shall be carried out.Due to the relatively high and narrow section size of ordinary I-beam and light I-beam, which makes it very limited in the scope of application. The use of I-beam shall be selected according to the requirements of design drawings.Metallization: refers to the process of penetrating metal atoms into the surface layer of alloy steel pipe. It is to alloy the surface layer of steel so that the workpiece surface has the characteristics of some alloy steel. Aluminizing, chromizing, boronizing, siliconizing and so on are commonly used in production.
