The production methods of seamless pipe are roughly divided into cross rolling method and extrusion method. The cross rolling method is to drill the tube with a cross roll, and then extend it to the rolling mill. This method has fast production speed, but has high requirements for the workability of the blank. It is mainly suitable for the production of carbon steel and low alloy steel pipes. The extrusion law is to pierce the blank or ingot with a punch, and then squeeze it with a steel pipe with an extruder. The efficiency of this method is lower than that of cross rolling method. It is suitable for producing high-strength alloy steel pipe. The billet or ingot must be heated before cross rolling method and extrusion method. The produced steel pipe is called thermal correlation. Steel pipes produced by hot working can sometimes be cold worked as needed. There are two methods of cold working. One is cold drawing. In other words, pull the pipe to the pipe and tilt it to make the steel pipe gradually thinner and longer. Another method is cold rolling. The method of applying the hot smoke invented by brother to cold processing. The cold working of seamless pipe can improve the dimensional accuracy and finishing of steel pipe, what are the customer&#;s requirements and standards during acceptance? When the galvanized pipe is accepted,Products Show you can judge whether it is qualified from the appearance,Lubbock273 débitmètre sans soudurePièces usées or whether there are problems such as missing plating or bubbles on the outer wall of the whole square pipe. Only by solving these problems in time can it be judged as qualified and better used.

eOlanjestadIn order to make the welded pipe have the required mechanical, physical and chemical properties, in addition to the reasonable selection of materials and forming process, heat treatment process is often necessary. In addition, the mechanical, physical and chemical properties of aluminum, copper, magnesium, titanium and their alloys can be changed by heat treatment to obtain different service properties.

The whole structure is composed of zinc and quaternary crystals,Products Show forming dense crystals and barrier layer on the plate, which effectively prevents the penetration of corrosion factors. From the point of view of the strong zinc corrosion resistance of the barrier layer, when the zinc sacrificial anode is at the forefront of protection, the scratches and scratches of some coatings and the insolubility of zinc oxide layer play a protective and blocking role.

DSan Pablo 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 etc.

FuGalvanized pipes are designed to maintain high enough corrosion resistance.

Quality requirements


How are seamless tubes made?

yWhen 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.

ERelatively 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,Products Show which greatly increases the strength and integrity of the pavement.

OWelcome calls Galvanized pipe is actually galvanized pipe. This is mainly because it increases the corrosion resistance of the steel pipe, so it is evenly coated with a layer of zinc. It can prevent the erosion of other chemicals such as and steam,Lubbock273 débitmètre sans soudurePièces usées and protect the steel strip. It is non-destructive and effectively prolongs its service life. Generally, the steel strip purchased is rolled into a large number by the galvanized pipe manufacturer, so pay attention to it during storage.

hXHardness of reinforcement construction of reinforced mesh on concrete bridge deck; Including key lime mixing and packaging materials, you need to pay attention to calculating the size of the building and the calculated specifications must meet the quality standards and construction standards.

After the above process, the next step is the polishing process of stainless steel pipe. There are network standards for internal and external wall finishing of pipelines, which corrodes slowly in acid, alkali and other fog, and can effectively maintain the steel matrix;

Marketing Departments . the straight length of the hook of the surface mesh reinforcement at the grid support shall not be less than mm,Reinforcement, galvanized pipe, seamless pipe, welded pipe, alloy pipe, I-beam-Shandong Kaiwen metal material Co., Ltd and the bending diameter shall not be less than D (D is the reinforcement diameter).

O Mixed pass system. According to the characteristics of rolling mills and products, in order to give full play to the advantages of their respective systems and overcome their disadvantages, mixed pass system is often adopted, the combination of more than two systems. For example, straight leg cross rolling pass system is adopted for finished hole and front hole of finished product, and bent leg cross rolling system is adopted for other passes; or direct rolling system is adopted for rough rolling hole and straight rolling system is adopted for the last ~ finish rolling holes Leg oblique tie hole, etc.
