There are five main guarantee measures for steel pipe welding. If these five aspects are guaranteed, the quality of galvanized pipe can also be guaranteed.

2The two ends of the steel produced by the seamless pipe manufacturer shall be cut into right angles, which is the raw material used by the seamless pipe manufacturer. The embryo prototube embryo needs to be cut by a cutting machine to form an embryo material with a length of about one meter, which is sent to the furnace for heating through the conveyor belt. The billet is sent to the furnace. After internal heating, the temperature is about degrees, and the fuel used is often ethyne. Temperature control in the furnace is a very key factor.

splace Cross rolling pass system. This pass system refers to that the two open legs of the I-beam pass are not on the same side of the waist at the same time,Products Show and the waist has an included angle with the horizontal axis.

If the surface of the welded pipe is rusty,St. ChristopherCustom welded pipeCauses of surface corrosion we can polish the appearance of the welded pipe with a wire brush to prevent rust.

NMoro The pollution of the joint causes the welding cracking. The composite pipe welding is an accurate work. If it is not done well, it will not only waste resources, but also lead to work efficiency, rework and restart and waste financial resources.

XoThe seamless pipe produced by the seamless pipe manufacturer is a long seamless pipe without any joints around and with hollow section. The thicker the wall of this product produced by the manufacturer, the higher the use value and economic value of this product. If its wall thickness is thinner, its processing composition will increase significantly, Secondly, the product technology produced by this seamless pipe manufacturer often determines its limitations.

Relatively 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.

The second is the control of welding materials to ensure that the welding materials purchased are from formal channels, with quality assurance certificate and certificate, which meet the process requirements; The recovery of welding rod head shall be strictly controlled to ensure the flow direction and dosage; Welding materials shall be baked in strict accordance with the process, and the amount of one-time distribution shall not exceed half a day.

w H-section steel is an economic section steel with better mechanical properties than I-section steel. It is named because its section shape is the same as the English letter "H". The flange of hot rolled H-beam is wider than that of I-beam, H-beam is lighter than I-beam.

MGalvanized pipes are used in construction, machinery manufacturing, steel construction and other projects, shipbuilding, solar power generation support, steel structure engineering power engineering,Products Show power plant, agricultural and chemical machinery,St. ChristopherCustom welded pipeCauses of surface corrosion glass curtain wall, automobile chassis, airport, boiler construction, highway railing house construction, pressure vessel, oil storage tank, bridge,Reinforcement, galvanized pipe, seamless pipe, welded pipe, alloy pipe, I-beam-Shandong Kaiwen metal material Co., Ltd power plant equipment, Hoisting and transportation machinery and other welded structural parts with high load.

KMarket trendAccording to the shape of the product, special flour, welding or ordinary thread connection shall be used.

bGThe 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, and improve the mechanical properties of materials.

East West derusting: if the galvanized pipe surface is rusty, the manufacturer will choose East West derusting and polish it with a steel wire brush

Recently, the price of zinc has been falling continuously. The key reason lies in the soft skin of galvanized pipe consumption and the slow start of production and marketing rate of manufacturing industries in the middle and lower reaches after the Spring Festival. The disadvantage of zinc price has long been far beyond the level of cyclical factors. The main performance of no prosperity in the hot season is whether the market situation in the off peak season will become a more worried problem in the galvanized pipe sales market.

For more, please checkcIn order to ensure the welding quality of welded pipe, the forming roll, extrusion forming roll and sizing roll must be adjusted once, and then the most important thing is to adjust the closing plate hole guide roll and extrusion forming roll of the forming roll. Among them, the guide roller has the s of controlling the weld direction of the welded pipe and the height width ratio of the finished rolled pipe, reducing the edge widening, controlling the edge springback of the finished rolled pipe, and ensuring that the weld is vertical without screwing into the extrusion roll.

FI-beam is a kind of economical section steel with better section mechanical properties. Its characteristics are as follows:

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, wire drawing, bending and so on without damaging the coating;

jplaceThey are not affected by surrounding factors and processes, including corrosion.

oD Spiral seam high-frequency welded steel pipe (sy- for general low-pressure fluid transportation takes hot-rolled steel strip coil as pipe blank and is often spiral formed at warm temperature. High frequency lap welding method is selected for welding spiral seam high-frequency welded steel pipe for general low-pressure fluid transportation.

Generally in terms of strength, the production efficiency is very high, and there are many varieties and specifications. The demand for RHS by equipment and capital is very small, which is suitable for the production of small galvanized steel pipe plants. However, the strength of steel is much lower than that of seamless steel pipe. It is mainly used for drying, redox method and characteristic table.
