The reinforced concrete surface reinforcement method has the advantages of simple construction technology and strong adaptability, which can greatly improve the bearing capacity, flexural stiffness and ductility of the brick wall. At the same time, its natural frequency can be changed to improve its performance in normal use. It is mainly applicable to the solid wall, porous hollow brick wall and mm thick empty bucket brick wall with no cracks and shear in the original wall.

Straight seam electric welding steel pipe (yb- is a steel pipe whose weld is longitudinally parallel to the steel pipe. It is usually divided into metric welded steel pipe, welded thin-walled pipe, transformer cooling oil pipe, square steel pipe, oval steel pipe, triangular steel pipe, hexagonal steel pipe, rhombic steel pipe, octagonal steel pipe,Products Show semi-circular steel pipe, others.

When the end span plate is connected with the concrete beam for structural reinforcement, the extended reinforcement shall be bent . When the perimeter of the floor is poured integrally with the concrete beam or wall, the length of the surface mesh reinforcement extending into the beam shall not be less than the anchorage length of the small reinforcement required by the standard (without transverse reinforcement), when the beam width is small, the extended reinforcement shall be bent.

Spiral seam high-frequency welded steel pipe (sy- for general low-pressure fluid transportation takes hot-rolled steel strip coil as pipe blank and is often spiral formed at warm temperature. High frequency lap welding method is selected for welding spiral seam high-frequency welded steel pipe for general low-pressure fluid transportation.

nThe specification of I-beam is expressed in cm of waist width. For example, the waist width of No. I-beam is cm. The types of I-beam include hot-rolled ordinary I-beam Light I-beam and wide parallel leg I-beam (H-beam). The waist width of hot-rolled ordinary I-beam in China is ~ mm,Products Show expressed as No. ~ No., and the inclination of inner side wall of leg is : The pass system of rolled I-beam includes direct rolling pass system,Mississauga20 seamless pipe manufacturerDiversified performance improvement cross rolling pass system and mixed pass system. In addition I-beam can also adopt special rolling method.

ZprojectThe use of hot dip galvanizing has expanded with the development of industry and agriculture. Therefore, hot-dip galvanized products have been widely used in industry (such as chemical equipment, petroleum processing, marine exploration, metal structure, power transportation, shipbuilding, etc.),Reinforcement, galvanized pipe, seamless pipe, welded pipe, alloy pipe, I-beam-Shandong Kaiwen metal material Co., Ltd agriculture (such as sprinkler irrigation, heating room), construction (such as water and gas transportation, wire casing, scaffold, house, etc.), bridges, etc. because hot-dip galvanized products

vI Manganese: it can improve the strength of steel, weaken and eliminate the adverse effects of sulfur, and improve the hardenability of steel. High alloy steel (high manganese steel) with high manganese content has good wear resistance and other physical properties

The third is the welding machine which must ensure reliable performance and meet the process needs; The welding machine must have qualified ammeter and voltmeter to ensure the correct implementation of welding process. The welding cable shall not be too long, and the welding parameters shall be adjusted when it is too long.

The chemical composition of cold-rolled ribbed strip is the same as that of hot-rolled smooth round strip. It is rolled at room temperature with hot-rolled smooth disc strip, which is called cold rolling. Due to the reorganization of steel crystal structure by cold rolling process, high tensile strength (LL, ll, ll, etc.) is obtained, which has poor ductility and cannot be welded. If there are double-sided ribs and three-sided ribs, the specification allows LL to be used as stirrup. The design value of strength is limited to n / mm?.

Where is goody China is a big steel country.

LXhy- series high hardness alloy I-beam; Undertake drawings and process wear-resistant pipes( Φ ≥mm); Undertake the processing and production of vulnerable parts of cement machinery; Welding technology consultation and service; The wear-resistant layer of alloy wear-resistant plate of high chromium heap welding flux cored wire series is mainly high chromium, as well as manganese molybdenum, niobium francium and other components. The alloy carbide formed has strong stability at high temperature.

Installation of galvanized pipe and precautions

jNATO gramsThe correct and reasonable use of galvanized pipe can play a better role. The product can be widely used in the market because of its obvious performance advantages. Both strength and toughness are worth our choice. Let&#;s see what the specific uses are and what the acceptance standards are?

oBThe grid spacing size and number of reinforcement of electric welding reinforcement mesh are correct, which overcomes the phenomenon of large spacing size error and missing binding and buckle of binding quality caused by manual placement of reinforcement in traditional manual binding. The welded steel mesh has high strength and good elasticity. When pouring concrete, the steel bar is not easy to be partially bent and does not change. Because it is considered that the longitudinal and transverse steel bars are spot welded into a mesh structure, so as to achieve the goal of side-by-side average stress and bonding anchor.
