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.→ under the same section load, the weight of hot-rolled H steel structure is reduced by % - % compared with the traditional structure.Peristri, Quality requirementsIts heat sealing effect is remarkable. It can be directly buried immediately, which can not only save resources, but also reduce consumption, not occupy the natural environment,PeristriHow much is a 40 galvanized pipe, but also purify the environment. The transportation of gas can meet the requirements of long-distance transportation, prevent actual operation and maintenance, reduce heating equipment, unique and convenient installation, and reduce the construction cycle time of the project. On the whole, it is more convenient to use. It can also be used for the transportation of floor heating and hot springs.Burao,Alloy pipe can be divided into round steel pipe and special-shaped steel according to different cross-sectional area. Because the circular area is large on the premise of the same side length, a large amount of liquid can be transported with an annular tube. In addition, when the circular cross section bears the internal or external axial working pressure, the bearing force is more symmetrical. Therefore, most seamless steel pipes are round steel pipes.The crack mainly occurs at -mm from the edge of the alloy pipe. The shape is several parallel vertical cracks of different sizes. The regularity is that the thicker the specification and model of the alloy pipe is The wider the width, the more serious the disadvantages.Plan option : Martensitic chromium alloy pipe,

Hot push hole diameter. More sensitive applications and facilities of such methods require simplicity, easy maintenance, durable economic development and convenient product specification transformation. For example, the production of large diameter must be grooved pipe, elbow and similar products. You only need to add some spare parts. The expansion method of hot push can be used to process and manufacture large-diameter, thick wall and thin alloy steel pipes, and can not exceed the working capacity of thick wall pipes of machinery and equipment. The reinforcement on both sides of the inverted beam extends into the beam respectively, and the anchorage length of the reinforcement is the same as that of the reinforcement, without hook.The system is mainly composed of control box,PeristriTelephone number of 310S stainless steel seamless pipe manufacturer, finishing roller, pre leveling unit, finishing unit and straightening unit.Test method,Generally, the process of pickling and passivation will be carried out for alloy pipes, but the alloy pipes after pickling and passivation are very easy to rust. Therefore, the way to find a solution to wiredrawing corrosion is 'grinding and polishing'. Due to grinding and polishing, there is no harm to carry out hot galvanizing in the middle and later stage.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 features: the content of chromium carbon alloy is -%, the hardness of chromium carbide alloy is V, and the macro hardness is - HRC

Function of I-beam: where is I-beam mainly used?manufacturer,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.General welded pipe: General welded pipe is used to transport low-pressure fluid. It is made of qa, qa and QA steel. It can also be made of other mild steel that is easy to weld. Water pressure, zigzag, flattening and other tests shall be carried out for steel pipes, and there are certain requirements for surface quality. Generally the delivery length is -m, and fixed length (or double length) delivery is often required. The standard of welded pipe is expressed in nominal diameter (mm or inch). The nominal diameter is different from the actual. Welded pipe can be divided into general steel pipe and thickened steel pipe according to the specified wall thickness, parts shall be dried with air compression or hot gas, or drying treatment or air drying can be selected.Peristri,Application scope of alloy pipe→ the two surfaces of the flange are parallel to each other, making it easy to connect process and install. The defects can be removed by grinding with sand wheel, but the remaining wall thickness must be within the allowable standard.
