External steel bonding reinforcement method is a more traditional reinforcement method. The utility model uses an adhesive to paste the steel plate or reinforcement mesh on the cracked part of the wall to achieve the purpose of reinforcement. The commonly used adhesive is usually epoxy resin. This method is simple and fast in construction and has little impact on production and life. Basically, the bearing capacity of the wall can be greatly improved without changing the shape and internal use space of the components. It is mainly applicable to the reinforcement of walls that do not allow to increase the section size of original components, but can greatly increase the section bearing capacity. Peak crackCalceta,I-beam, also known as universal beam, is a long strip of steel with I-shaped section. I-beam is divided into ordinary I-beam and light I-beam. It is a section steel with I-type section shape.b. The professional two-sided arc welding processing technology can complete the electric welding at a good position, which is not easy to have the disadvantages of staggered joint,EnantiomerQ345B welded pipe manufacturer, welding deviation and incomplete penetration, and it is very easy to manipulate the welding quality.Requirements of alloy tubes for low and medium pressure boilers

Patented manufacturing process of I-beam: I-beam has become a new industrial standard for wear-resistant materialsWelded steel pipe, also known as welded pipe, is a seamless steel pipe made of thick steel plate or hot-rolled strip by electric welding after coiling and forming, generally with a fixed length of m. Welded steel pipe has the advantages of simple production and processing process, high production efficiency, many types, specifications and models,Enantiomer18 how much is I-beam per meter,EnantiomerSeamless pipe manufacturer’s telephone, and less investment in machinery and equipment projects but the general compressive strength is less than that of seamless pipe.At present,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.H-section steel is an economic section high-efficiency profile with more optimized section area distribution and more reasonable strength weight ratio. It is named because its section is the same as the English letter 'H'. There is no slope on the inner side of the two outer edges of H-section steel, which is straight. This makes the welding and splicing of H-section steel simpler than I-section steel, better mechanical properties per unit weight, and can save a lot of materials and construction time.Greatly reduce the environmental pollution caused by abrasion, damage and blanking, and increase the labor cost of material cleaning

Alloy pipes can be used for heating (cooling) projects.Welcome calls ,Due to the relatively high and narrow section size of ordinary I-beam and light I-beam, the moment of inertia of the two main axes of the section is quite different, 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.Galvanized pipes are designed to maintain high enough corrosion resistance.Plan scheme : Martensitic chromium alloy pipe and chromium alloy pipe with Cr composition exceeding %, without high carbon steel and high chromium alloy pipe. The aqueous solution contains % sodium cyanide % ~ % (volume ratio), the solution temperature is ~ ℃, and the solution time is min.Enantiomer,Alloy steel pipe is a new type of seamless steel pipe connection pipeline. The selection of pipeline connection pipeline whether it is fire water system software, water supply equipment, heat and national defense industrial pipeline system software of petrochemical pipeline system, alloy steel pipe stimulates important effects.c. quality inspection is carried out for alloy pipes, so that the whole process of steel pipe processing is under reasonable inspection and supervision, and the product quality is reasonably guaranteed. The small length of repair welding is mm; The raw material shall not exceed mm after grinding by welding edge.
