I-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, Xuanhua Iron and steel, Japan iron and steel, etc.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.Coyoacan ,Check whether the manufacturer&#;s qualification, business license, organization code certificate, investigate the supplier&#;s performance and the projects served in the past. Whether there is a self built logistics fleet or not, choosing a service provider with a self built logistics fleet can reduce the transportation cost, and more importantly, ensure the timeliness of delivery. After sales service, whether there is a sound and reliable after-sales service guarantee system, and timely solve quality problems in arrival acceptance and subsequent use. Check whether the quality assurance materials such as product quality certificate, material specification and warranty are complete. Check the appearance of the welded pipe, the surface is smooth and flat, the weld is dense, oil stain, corrosion, and the standard wall thickness deviation shall not exceed % - %. NDT shall be carried out for welded pipe with flaw detector. Conduct bending tensile strength test according to the requirements bend the welded pipe for degrees, and there is no crack at the bend. The defects can be removed by grinding with sand wheel, but the remaining wall thickness must be within the allowable standard.Taytay,The production process can be summarized as follows: pre leveling → finishing → straightening → post leveling. Flat steel / A / B steel with width of -, thickness of -, rectangular section and slightly pure edge. Flat steel can be finished steel, or it can be used as blank for welded pipe and thin slab for laminated thin plate.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.Greatly reduce the environmental pollution caused by abrasion, and increase the labor cost of material cleaning

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.Galvanized pipes are used in construction, machinery manufacturing, steel construction and other projects, shipbuilding, solar power generation support, steel structure engineering, power engineering, power plant, agricultural and chemical machinery, glass curtain wall automobile chassis, airport, boiler construction, highway railing, house construction, pressure vessel, oil storage tank, bridge, power plant equipment, Hoisting and transportation machinery and other welded structural parts with high load.Key technical characteristics of alloy pipeOK or not?,Performance parameters and application scope of I-beamThe working principle of flat steel finishing machine in I-beam production process is to pre level and finally level the cold flat steel with two groups of leveling wheel sets staggered up and down in the thickness direction; A pair of finishing wheels arranged relatively are used to extrude the width direction, so that the width is compressed to achieve the expected parameters,Coyoacan What is the price of seamless pipe, and the compression amount is adjustable; Straighten the width with staggered straightening wheels.At present, there is still a big gap in the production technology of C-section steel between China and foreign countries.

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, yibai%sx ray or ultrasonic testing shall be carried out. For the spiral welding of alloy pipes for the transportation of water,Coyoacan Q235B welded pipe manufacturer, wastewater, gas, heating steam and other general liquids, X-ray or ultrasonic testing sampling inspection (%) shall be carried out.Quality documents,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.Galvanized pipe features: Peak crackCoyoacan ,It is widely used in various fields of national economic construction, such as buildings, bridges, power stations, oil drilling platforms, vehicles,Coyoacan 16Mn thick wall welded pipe, highways, subways, steel structure plants and large warehousesHeating surface tubes for low and medium pressure boilers (working pressure is generally not greater than MPA and working temperature is below ℃);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, quenching machinery and equipment cannot be lacked. Therefore, 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.
