Peak crackAll the cracks occur at -mm away from the edge below the alloy pipe, showing a 'high mountain' shape.Burrell,How are seamless tubes made?Alloy pipe is a spiral seam seamless steel pipe, which is made of hot-rolled strip steel coil, 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.Janakpur,What are the requirements for alloy pipe construction accessoriesDefects of alloy pipe and solutions:Mixed Scabs are distributed periodically, and the situation after casting and rolling is significant through edge flame peeling crack inspection or billet scratch flame removal.

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.Longitudinal welded pipe has the advantages of simple production process, high production efficiency, low cost and rapid development. The strength of spiral welded pipe is generally higher than that of straight welded pipe. It can produce welded pipe with larger pipe diameter with narrow blank,BurrellWelded pipe price, and welded pipe with different pipe diameter with blank of the same width. However, compared with the straight seam pipe with the same length, the weld length increases by ~ , and the production speed is low. Welded pipes with large or thick diameter are generally made of steel blank directly, while small welded pipes and thin-walled welded pipes only need to be welded directly through steel strip. Then after simple polishing, wire drawing is OK. Welded pipe is welded with strip steel, so it is not as high as seamless pipe in its original position. Welded pipe process: uncoiling of raw materials - leveling - end shearing and welding - looper - forming - Welding - removal of internal and external weld beads - pre correction - induction heat treatment - sizing and straightening - eddy current testing - cutting - hydraulic inspection - Pickling - Inspection (strict control) - Packaging - delivery.The general alloy pipe with improved performance is variable and has high application value. The alloy pipe contains more Cr and is heat resistant Low temperature resistance Corrosion resistance. There is no aluminum alloy in plain carbon seamless steel pipe, not very little aluminum alloy, and the alloy pipe is used in crude oil Aerospace Chemical plant Power engineering heating furnace. Because the physical properties of alloy tubes are easy to change and adjust.knowledge,Burrell15CrMo small diameter alloy pipe,The general alloy pipe with improved performance is variable and has high application value. The alloy pipe contains more Cr and is heat resistant Low temperature resistance Corrosion resistance. There is no aluminum alloy in plain carbon seamless steel pipe, not very little aluminum alloy, and the alloy pipe is used in crude oil Aerospace Chemical plant Power engineering heating furnace. Because the physical properties of alloy tubes are easy to change and adjust.I-beam, also known as steel beam, is a long strip of steel with I-shaped section. I-beam is divided into ordinary I-beam and light I-beam. It is a section steel with I-type section shape.The core of C-section steel is the structural system of braced frame. More than half of such senior managers in China are the former. Unfavorable to earthquake resistance. Hydraulic power, and the power is large, generally about KW, which is similar to the plate shearing and bending machine. The general control process is complex, and PLC control is mostly used.

Main uses: as a finished material, flat steel can be used to make hoop iron,BurrellCustom welded pipe, tools and mechanical parts, 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.Respect for customers,The shape of small longitudinal crack on the surface of alloy pipe is less than mm The overall width is less than mm The depth is lower than .mm.Spiral welded pipe: it is made by rolling low-carbon structural steel or low-alloy structural steel strip into pipe blank according to the viewpoint of certain spiral line (called forming angle), and then welding the pipe seam. It can produce large-diameter steel pipe with narrow strip steel. Spiral welded pipe is mainly used for oil and natural gas transportation pipeline, tensile strength and cold bending of the weld meet the requirements.Due to the unique performance of I-beam, I-beam has successfully solved the problem of serious equipment wear in many industries.BurrellIts heat sealing effect is remarkable. It can be directly buried immediately, 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.With the development of steel structure buildings, only I-beam is not enough that is, thickened I-beam which is easy to lose stability for load-bearing columns.H-shaped steel groove is deep and thick, and can withstand forces in two directions.
