Classification by use

5 As long as the pipe material is high-strength alloy steel, including alloy steel pipes with temperature resistance, wear resistance and low temperature resistance, the welding process shall be focused on preventing the tendency of martensite structure and cracks due to welding high-temperature operation. The general process requirements are that the welding rod shall be selected and baked as required and sent to the welder for use. The oil and water shall be removed before welding on both sides of the weld Rust and sundries shall be removed and cleaned. The welding line energy shall be as small as possible to minimize the swing during the welding process. The arrangement of the last weld shall have annealing effect on the heat affected zone as far as possible. Slow cooling after welding, cover with asbestos cloth, etc.

nKingstonAiming 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,Products Show eliminate structural defects,ريتشموند ›DN25 المجلفن الأنابيب كم لكل مترانعكاس، ارتداد، انقلاب 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, and the allowable deviation above m is no more than mm. The allowable deviation of horizontally installed pipes is mm per meter.

VAsiut Because zinc has excellent ductility and its alloy layer is firmly attached to the steel base, hot-plated parts can be formed by cold stamping, rolling,Products Show wire drawing, bending and so on without damaging the coating;

Xc Manganese: it can improve the strength of steel weaken and eliminate the adverse effects of sulfur, which takes hot-rolled steel strip as pipe blank and improve the hardenability of steel. High alloy steel (high manganese steel) with high manganese content has good wear resistance and other physical properties

The development of steel bar mesh is in line with the development of energy-saving economy

Spiral seam high-frequency welded steel pipe (sy- for pressure fluid transportation is a spiral seam high-frequency welded steel pipe used for pressure fluid transportation, often warm spiral forming and high-frequency lap welding method. The steel pipe has strong pressure bearing capacity and good plasticity, which is convenient for welding and processing; After various strict and scientific inspections and tests, the application is safe and reliable, the diameter of steel pipe is large, the transportation efficiency is high, and the investment in laying pipeline can be saved. It is mainly used for laying pipelines for transporting oil, etc.

mMain uses: as a finished material,Products Show flat steel can be used to make hoop iron, tools and mechanical parts,ريتشموند ›DN25 المجلفن الأنابيب كم لكل مترانعكاس، ارتداد، انقلاب and used as building frame structural parts and escalators in buildings. Flat steel is divided into two types according to its shape: plane spring flat steel and single-sided double groove spring flat steel. Hot rolled spring flat steel is mainly used to manufacture leaf springs for automobiles, tractors, railway transportation and other machinery.

A Steel pipe with complex section -- unequal hexagonal steel pipe, five petal quincunx steel pipe, double convex steel pipe, double concave steel pipe, melon seed steel pipe, conical steel pipe,Reinforcement, galvanized pipe, seamless pipe, welded pipe, alloy pipe, I-beam-Shandong Kaiwen metal material Co., Ltd corrugated steel pipe, also known as welded pipe is a seamless steel pipe made of thick steel plate or hot-rolled strip by electric welding after coiling and forming, generally with a fixed length of m. Welded steel pipe has the advantages of simple production and processing process, high production efficiency, many types, specifications and models, and less investment in machinery and equipment projects, but the general compressive strength is less than that of seamless pipe.

Polished stainless steel pipes shall be subject to internal inspection and strict manual selection by the steel pipe quality inspector through metal detector (or hydrostatic test), and qualified products shall be packaged and delivered.

Pure zinc layer is a plastic zinc layer in hot-dip galvanizing. Its properties are basically close to pure zinc and have ductility, so it is flexible. Galvanized pipe is widely used in architecture. This product must have been seen by everyone. However, there are many types of it. When you buy it, you should also find out which one you need. The reason why it is favored by everyone in the market is inseparable from its advantages. Next Xiaobian will lead you to see the advantages of galvanized pipe.

property rightrThe fifth is the welding environment control to ensure that the temperature, humidity and wind speed during welding meet the process requirements.

ZPlan scheme : for high carbon steel with carbon content of more than .% and high chromium alloy pipe with chromium content of no less than %, the interval is min.

For the surface mesh of the height difference plate, when the height difference is ≤ mm, the surface mesh can be bent and installed; when the height difference plate is more than mm, the surface mesh should be disconnected at the place with height difference and put into the beam respectively. The anchorage length of the reinforcement is required for the reinforcement to extend into the beam.

cKingstonKeep the combustion supporting gas and use it reasonably to avoid fracture of the welding interface. Problems in the welding of steel wire mesh skeleton composite pipe are common, which should be prevented or solved.

zVFrom the comparison of the monthly summary apparent consumption data information of galvanized pipe and the real estate sales data information from to this year, 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.

When the mesh reinforcement on both sides of the beam is different, the reinforcement on both sides extends into the beam, and the reinforcement anchorage length is required.
