Last week, the billet in North China market showed a slight rebound trend. The billet quotation in Tangshan, the leading city, rose first and then stabilized in four trading days, with a strong wait-and-see atmosphere in the market. Affected by the almost stagnation of festival procurement, although the phase snail is still running at a low level, due to the small billet resources in the market the steel mills unexpectedly rose, and the billet market rebounded. However, due to the continuous increase of capital pressure and the downturn in the transaction of downstream finished materials, the steel plant has always maintained a cautious wait-and-see attitude to maintain stability.Introduction to product knowledge of alloy pipe:Ostankako,Classification by production methodI-beam is a long strip steel with groove section, which belongs to carbon structural steel for construction and machinery. It is a section steel with complex section, and its section shape is groove shape. China&#;s imports of I-beams are greater than its exports. The main producing areas are Tangshan Iron and steel, Baotou Iron and steel, Shangang, huangte,OstankakoI-beam price quotation, Maanshan Iron and steel, Japan iron and steel, etc.Kampong Pangkal Kalong, Small longitudinal crackWhen 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, cold and corrosion prevention. In addition, the chemical raw material transmission pipeline has a wide indoor space.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.

According to the theory of steel structure, the I-beam flange should be stressed, that is, the I-beam should be standing rather than lying down. Spiral welded steel pipe (sy- for pile is made of hot-rolled steel strip coil as pipe blank, often warm spiral forming, double-sided submerged arc welding or high-frequency welding. It is used for foundation pile of civil building structure, wharf, bridge etc.C-section steel has uniform zinc layer, smooth surface strong adhesion, no zinc scar, no zinc leakage and high dimensional accuracy. All surfaces are wrapped by zinc layer, and the zinc content on the surface is usually -g /? It has long service life, corrosion resistance and durability. It is a kind of stronger protection.Quality risk,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,OstankakoHow much is 80 welded pipe per meter, cold and corrosion prevention. In addition, the chemical raw material transmission pipeline has a wide indoor space.When selecting I-beam in structural design reasonable I-beam shall be selected according to its mechanical properties, chemical properties, weldability and structural size.It can withstand continuous moderate impact and can provide composite plates of various thicknesses

Aiming at the connective tissue and texture produced in stainless steel plate Position and other crystal defects are generally removed by heat treatment processes such as quenching or quenching. The effect of quenching is to optimize the crystal, eliminate structural defects, reduce strength, improve plastic deformation, and also conducive to cold drawing. In the production and manufacture of cold drawn alloy pipe, the formulation of appropriate annealing process is a necessary condition to ensure that the alloy pipe mechanism meets the standard and the commodity does not crack. If the manufacturer in order to better one sidedness, reduce the product cost and reduce the quenching process, it will eventually lead to bad harm to the product quality.Honesty and mutual benefit,Due to the unique performance of I-beam, I-beam has successfully solved the problem of serious equipment wear in many industries.Galvanized pipe features:→ compared with general section steel, it has the advantages of low cost, high precision and small residual stress. It does not need expensive welding materials and weld detection, and saves about % of the manufacturing cost of steel structure.Ostankako,OstankakoHow much is DN32 galvanized pipe per meter,Classification introductionHeating 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 ℃ ~ ℃)What is the purpose of flat steel
