Plan option : Martensitic chromium alloy pipe,Greatly reduce the environmental pollution caused by abrasion, damage and blanking, and increase the labor cost of material cleaningvictoria, Spiral seam submerged arc welded steel pipe (SY- for pressure fluid transportation is a spiral seam steel pipe used for pressure fluid transportation, which takes hot-rolled steel strip coil as pipe blank, often warm spiral forming and welded by double-sided submerged arc welding. The steel pipe has strong pressure bearing capacity and good welding . After various strict scientific inspections and tests, it is safe and reliable to use. The steel pipe has large diameter and high transportation efficiency, and can save the investment in laying pipelines. It is mainly used for transporting oil and natural gas.Its 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, but also purify the environment. The transportation of gas can meet the requirements of long-distance transportation, prevent actual operation and maintenance, meet the requirements of thermal insulation and cold protection, 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.Deinze,victoriaSA213T91 alloy pipe,b. The professional two-sided arc welding processing technology can complete the electric welding at a good position, which is not easy to have the disadvantages of staggered joint, welding deviation and incomplete penetration, and it is very easy to manipulate the welding quality.I-beam is mainly used in building structure, curtain wall engineering, mechanical equipment and vehicle manufacturing.The pickling agent in the pickling process contains many acidic substances,victoriaHow much is No. 16 I-beam per ton, including hydrochloric acid, sodium cyanide, etc. which has strong corrosion and reduction, and the temperature of etching substances is relatively high. Therefore, the corrosion resistance of alloy pipes is specified higher.

Alloy pipe is a spiral seam seamless steel pipe, often processed by warm extrusion and welded by automatic double wire double side arc welding process. The alloy pipe sends the hot-rolled strip steel to the welded pipe unit, and the hot-rolled strip steel is extruded through multiple passes. The hot-rolled strip steel is rolled slowly to produce annular pipe material with open mouth gap. Adjust the reduction amount of the extrusion roll to control the welding gap at ~ mm and make both sides of the weld flush.Galvanized pipe can be seen from its name. It is a square pipe type. Many materials can form galvanized pipe body. It is used for what purpose and where. Most galvanized pipes are steel pipes. After unpacking, leveling crimping and welding, they form round pipes, which are rolled into square pipes, and then cut into the required length. Generally, there are galvanized pipes in each package. In terms of spot, most of them are in large specifications,victoriaLongitudinal welded pipe manufacturer, ranging from * * .- to * * - Galvanized pipes are divided into structural galvanized pipes, decorative galvanized pipes, architectural galvanized pipes, mechanical galvanized pipes, etc.The 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, and the compression amount is adjustable; Straighten the width with staggered straightening wheels.superior quality, it is clearly proposed that water cleaning shall be carried out immediately after the aqueous solution, ~ times of water cleaning, and then chromic acid closed solution shall be carried out. Chromic acid solution must be carried out h after the subsequent water cleaning of metallographic structure and austenitic alloy pipe. Chromic acid aqueous solution (mass ratio) is % ~ % the solution temperature is ~ ℃, and the solution time is min. Then dry.I-beam is widely usedThe utility model has the advantages that the axial force of the roll is small, the axial movement is small, and the working slope is not required,

H-beam is a widely used profile in steel structure buildings. It is different from I-beam. The first is the flange, and the second is that the inner surface of the flange has no inclination, channel steel and angle steel.recommend,Advantages of using I-beam: reduce maintenance cost, reduce downtime, improve equipment operation rate, reduce wear, reduce equipment capacity and increase power consumptionThere are many processes in the process of welded pipe processing, and every detail needs our attention. Welded pipes need to be treated by various processes before application. Heat treatment of welded steel pipe is an important link in the process of welding steel pipe. Hot working is a metal hot working process in which metal materials are heated, and the metal properties are controlled by changing the metallographic structure on the surface or inside of the material.At present, there is still a big gap in the production technology of C-section steel between China and foreign countries.victoria,→ under the same section load, the weight of hot-rolled H steel structure is reduced by % - % compared with the traditional structure.Alloy tube is widely used in our daily life, which provides us with great assistance.Precision cold rolling of small and medium-sized bearing sleeves with alloy tubes can greatly improve material utilization, bearing performance and service life. This paper systematically introduces the development of high quality cold drawn bearing steel pipe and its application in bearing. Precision cold rolling of small and medium-sized bearing sleeves with bearing steel pipes can greatly improve material utilization, bearing performance and service life. This paper systematically introduces the service life of high quality cold drawn bearings.
