Frame line crack Judged as failing.Cape Haidi,With the development of China&#;s infrastructure, the investment in infrastructure continues to grow; Implement the strategy of western development. Economic construction has entered a new stage, and the demand for welded steel mesh for capital construction such as power, transportation, water conservancy, housing and municipal engineering will increase exponentially.Defects of alloy pipe and solutions:Michetia, The small length of repair welding is mm; The raw material shall not exceed mm after grinding by welding edge.Passivation treatment operation of alloy pipe Frame line crack

At the same height, light I-beam has narrower legs, thinner waist and lighter weight than ordinary I-beam. No. - is large I-beam, and No. - is medium I-beam. Imported I-beam shall be marked with actual specifications, dimensions and relevant standards.Longitudinal welded pipe has the advantages of simple production and processing technology, high production efficiency, low cost and rapid development trend. The compressive strength of spiral welded pipe is generally higher than that of straight welded pipe. Narrow blank can be used to produce welded pipe with large pipe diameter, and blank with the same total width can also be used to produce welded pipe with different pipe diameter. However, compared with the straight seam pipe with the same length, the welding length is increased by ~ , and the production rate is low.Stages needing attention in the production and manufacture of alloy tubeshowWhat is the purpose of flat steelDifference and application description between H-beam and I-beamX-ray or ultrasonic testing shall be carried out for repair welding of alloy pipe, dead end welding of strip steel and circumferential seam. For the spiral welding of steel for the transportation of flammable general liquids,Cape Haidi16Mn alloy pipe, yibai%sx ray or ultrasonic testing shall be carried out. For the spiral welding of alloy pipes for the transportation of water,Cape Haidi2205 stainless steel seamless pipe manufacturer, wastewater, gas, heating steam and other general liquids, X-ray or ultrasonic testing sampling inspection (%) shall be carried out.

Defects of alloy pipe and solutions:wholesaler, and honeycomb beam can be combined to form various section forms which greatly meets the needs of engineering design and manufacturing.Classification by wall thickness Judged as failing.Cape Haidi, Direct rolling pass system. The direct rolling pass system refers to the pass system in which the two open legs of the I-beam pass are on the same side of the roll axis at the same time,Cape HaidiHow much is welded pipe per ton now, and the waist is parallel to the roll axis.Alloy pipe is a very important way and type of seamless steel pipe. Its use is relatively common. It is widely used in various engineering projects, house construction and building decoration. Its fracture will always be found in the production, manufacturing and key marketing of alloy pipe, That is, the interval is min.
