Special shaped pipe: square pipe, rectangular pipe, cap pipe, steel pipe for hollow rubber steel doors and windows welded by general carbon structure steel and Mn steel strip mainly used as agricultural machinery components, steel windows and doors, etc.

2Welded pipe refers to the steel pipe with joints on the surface,Products Show which is welded after the steel strip or steel plate is bent and deformed into circular,كيساداq345b طولية الأنابيب الملحومة الصانعالمعالجة في الصناعة square and other shapes. The blank used for welded pipe is steel plate or steel strip. How can the steel strip or steel plate be welded together, and what are the welding skills?

aKanasKey technical characteristics of alloy pipe

Cold.

XHerzliaMetric welded pipe: it is used as seamless pipe in standard. The welded steel pipe expressed by outer diameter * wall thickness mm is welded by hot and cold strip welding of general carbon steel, high-quality carbon steel or Puneng low alloy steel or it is made by cold drawing after hot strip welding. Metric welded pipe is generally used as structural parts, such as transmission shaft, or to transport fluid. The thin wall is used to produce furniture and lamps. It is necessary to ensure the strength and zigzag test of steel pipe.

HdRelatively high stability and high deformation resistance. The mixture is usually composed of hard fine aggregate graded aggregate with high sand equivalent, especially micro seal and polymer modified seal, which greatly increases the strength and integrity of the pavement.

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,Products Show etc.

Straight seam welding is adopted for larger diameter welded pipe, and spiral welding is mostly adopted for large diameter welded pipe; According to the top appearance of seamless steel pipe, it is divided into annular welded pipe and special-shaped (square, pitch, etc.); according to different materials and main purposes, hot-dip galvanized welded steel pipe for bottom pressure liquid transportation, continuous conveyor idler electric welded steel pipe, etc. it is arranged from small to large according to diameter * wall thickness according to the specification, model and dimension table in the current standard.

A Material requirements

YHow many? It has a thick and dense pure zinc layer covered on the steel surface, which can prevent the steel substrate from touching with any corrosion solution and maintain the steel substrate from corrosion. In general atmosphere,Products Show the surface of zinc layer forms a thin and dense zinc oxide layer, which is difficult to dissolve in water,كيساداq345b طولية الأنابيب الملحومة الصانعالمعالجة في الصناعة so it plays a certain maintenance effect on steel matrix. If zinc oxide and other components in the atmosphere form insoluble zinc salts, the anti-corrosion effect is more ideal.

qOThe preparations for the construction of high-speed reinforcement mesh include the preparation and inspection of raw materials, the inspection and acceptance of the lower layer of the pavement, and the preparation of construction equipment and engineering machinery.

The smooth of steel pipe is mainly through tension reducing, the whole welded pipe is heated to more than ℃ by the welded pipe tension reduction process, and then rolled to finished pipes with various outer diameters and wall thicknesses by the tension reduction machine ( times in total). The fluid pipes produced by developed countries in the world have adopted the welded pipe smooth process in a large number of boiler pipes. With the development of society, Domestic hot welded pipe has gradually formed a situation to replace smooth pipe.

The vertical of the processed reinforcement bar shall be divided into small sections as required.

reformm Divided by weld -- straight welded pipe and spiral welded pipe.

PClassification introduction

Welded steel mesh, a new form of reinforcement is especially suitable for large-area concrete engineering.

cKanasFrom the comparison of the monthly summary apparent consumption data information of galvanized pipe and the real estate sales data information from to this year,Reinforcement, galvanized pipe, seamless pipe, welded pipe, alloy pipe, I-beam-Shandong Kaiwen metal material Co., Ltd they show the consistency of height width ratio, which not only shows a positive correlation in the overall new trend, but also significantly conforms to the fluctuation direction of the monthly development trend.

iLGalvanized pipe is a kind of light thin-walled steel pipe with hollow square section, also known as steel cold-formed profile. It is a section steel with square section shape and size, which is made of Q hot-rolled or cold-rolled strip or coil as the base material, cold bending and high-frequency welding. In addition to wall thickness thickening, the corner size and edge flatness of hot rolled extra thick wall galvanized pipe reach or even exceed the level of resistance welding cold formed galvanized pipe. Good comprehensive mechanical properties, weldability, and good low temperature toughness.
