Maple Ridge38CrMoAl alloy pipeThe structure and problems in the use process

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, 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 ~ ,Products Show and the production speed is low. Welded pipes with large or thick diameter are generally made of steel blank directly,Lesbridge38CrMoAl alloy pipeHow to promote industrialization quickly 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.

iMaple RidgeH-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.

Chromium can improve the hardenability and wear resistance of steel, and improve the corrosion resistance and oxidation resistance of steel

MTanzaniaOn the other hand, that is, austenite transforms into martensite, the increase of specific volume will be accompanied by the expansion of workpiece volume,Products Show and each part of workpiece will undergo phase transformation successively, resulting in inconsistent volume growth and structural stress. Due to the change of tissue stress, the tensile stress on the surface and the compressive stress in the heart are just opposite to the thermal stress. The magnitude of microstructure stress is related to the cooling rate, cracks and hollows show that the construction materials are unqualified, the construction at the matrix junction is not in place, and the construction personnel are poor. The external wall plastering adopts electric welding steel wire mesh, which can prevent cracking and strengthen the wall.

In building construction engineering, welded steel wire mesh is an essential heat preservation and crack prevention material. It has good performance and can take into account the unity between crack resistance and the requirements of face brick for base strength and the stability of heat preservation system.

OGood quality Steel mesh guardrail (steel mesh fence) steel mesh guardrail refers to the guardrail made of steel mesh. It is stronger and more durable than the guardrail made of electric welding mesh, steel mesh, hook mesh,Products Show etc., but its cost is much higher,Lesbridge38CrMoAl alloy pipeHow to promote industrialization quickly and it is rarely used under normal circumstances

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.

analysisy For the surface mesh of the height difference plate corrugated steel pipe, 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.

Application of galvanized pipe

fMaple Ridge Pipe installation

bYIn our daily life and work, we can often see a lot of steel products. At the same time, among many steel products, the figure of galvanized pipe is particularly prominent. This is because this kind of pipe will be applied to many engineering construction we often see in our life. There are also countless products processed with this kind of pipe. For example, in the field of mechanical equipment processing we often see, the application of galvanized pipe is more frequent. Let&#;s discuss the application scope of this kind of pipe today.
