X-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, yibai%sx ray or ultrasonic testing shall be carried out. For the spiral welding of alloy pipes for the transportation of water, wastewater, heating steam and other general liquids, X-ray or ultrasonic testing sampling inspection (%) shall be carried out.The sodium cyanide passivation treatment of alloy pipe can be divided into four categories. Before passivation treatment, the surface of alloy pipe shall be clear of oil stains, pickled and passivated. Passivation treatment can be carried out only after the surface is cleaned, and the workpiece of alloy pipe products can be infiltrated into aqueous solution. The passivation treatment of the alloy tube in sodium cyanide transforms the surface layer into a very thin passivation treatment film, which determines that the color of the surface layer has no change before and after passivation treatment, and the reproducibility of the solution is good.Santa Cruz de elsebo,Wire sleeve: it is also a general carbon steel welded steel pipe. It is used in concrete and various structural power distribution projects. The commonly used nominal diameter is from -mm. The wall of wire sleeve is thin, which is mostly used after coating or galvanizing, and cold bending test is required.When we carry out different projects, we must use different raw materials, which can ensure the quality of the project. In many kinds of data, alloy pipe is widely used. In many projects, so it is very popular in the field. When people carry out the construction of alloy pipe project,Santa Cruz de elsebo300 seamless pipe 1 meter how many kilograms, there are many things that must be paid special attention to. Let&#;s take you to know:Wichita,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,Santa Cruz de elseboIncoloy800 alloy pipe, generally about KW, which is similar to the plate shearing and bending machine. The general control process is complex, and the waist is parallel to the roll axis.

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, and the upper and lower surfaces are parallel. The section characteristics of H-beam are obviously better than those of traditional I-beam, channel steel and angle steel.Idler pipe: it is used for electric welding steel pipe of idler of belt conveyor. It is generally made of Q, QA B steel and steel, with a diameter of -mm. There are certain requirements for pipe tortuosity, end face straightness with the center line and ovality. Generally, water pressure and flattening tests are carried out.Introduction to product knowledge of alloy pipe:demand,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,Santa Cruz de elsebo12Cr1MoVG seamless pipe manufacturer, 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.Dry processing technology: after passivation treatment parts shall be dried with air compression or hot gas, or drying treatment or air drying can be selected.I-beam is a kind of economical section steel with better section mechanical properties. Its characteristics are as follows:

Alloy tube is widely used in our daily life, which provides us with great assistance.Free consultation,Alloy pipes are widely used in building materials and the test standards of alloy pipes are also different. Alloy pipe has high hardness and can be used at many levels, most of which is prestressed reinforcement. Where plastic deformation is not specified but compressive strength is specified, such stainless steel plate can be applied. When the end span plate is connected with the concrete beam for structural reinforcement, the length of the surface mesh reinforcement extending into the beam shall not be less than d. When the beam width is small, the extended reinforcement shall be bent . When the perimeter of the floor is poured integrally with the concrete beam or wall, the length of the surface mesh reinforcement extending into the beam shall not be less than the anchorage length of the small reinforcement required by the standard (without transverse reinforcement), when the beam width is small, the extended reinforcement shall be bent.Using alloy pipe to produce ring parts can improve the utilization rate of raw materials, simplify the production and manufacturing process, and save raw materials and production and processing construction time, such as roller bearing ring throwing Nowadays, seamless steel pipe has been widely used to produce hydraulic jack sleeve.Santa Cruz de elsebo,Passivation treatment operation of alloy pipePlan option : Martensitic chromium alloy pipe,Classification introduction
