. the straight length of the hook of the surface mesh reinforcement at the grid support shall not be less than mm, and the bending diameter shall not be less than D (D is the reinforcement diameter).

8In order to improve the corrosion resistance of steel pipe, the general steel pipe (black pipe) is galvanized. The galvanized pipe is divided into hot-dip galvanizing and electric steel zinc. The hot-dip galvanizing layer is thick and the cost of electric galvanizing is low, so there is galvanized pipe.

yGillard melenaI-beam, also known as universal 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.

On the other hand,Products Show when the steel structure changes during heat treatment,فيكتوريا دي لاس توناسأنا الصلب الشعاع الصانعاين اعمل that is, austenite transforms into martensite, the increase of specific volume will be accompanied by the expansion of workpiece volume, 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 shape and chemical composition of martensitic transformation zone materials.

WMendefeiraIn view of the current market environment, especially in terms of construction or equipment manufacturing technology, the position of galvanized pipe is still relatively large. It is precisely because of this strong position that we can see this kind of building material in all walks of life, even in a field that seems to have little contact. It will be applied in many construction projects. At the same time,Products Show even in the depressed environment of the steel industry, the application situation and utilization rate of this kind of pipe are very high.

McThe 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, so it has good bonding and anchorage with the concrete, and the load can be evenly distributed, which obviously shows the seismic cracking performance of the reinforced concrete structure. According to the actual test, the welded reinforcement mesh laid on the road can reduce the occurrence of cracks than the manual binding mesh. It greatly reduces the unnecessary cost generated manually in the construction and shortens the construction period. The use of reinforcement mesh is simple and convenient, and the reinforcement mesh is convenient for transportation.

The surface of cold galvanized layer is smooth dense and uniform. It has good mechanical properties and corrosion resistance. The consumption of hot-dip galvanized coating is between % - %. The galvanizing process is complex, surface coating and double-sided coating is different,Products Show so the thin-walled pipe shall be galvanized. The zinc coating has strong protection and corrosion resistance.

cAfter isothermal quenching treatment, the modified LNs steel of case hardening steel also has the surface compressive stress characteristics obtained by heat treatment.

How to judge the quality of seamless pipe?

Welcome to inquirep Main machines and tools

YDifference and application description between H-beam and I-beam

Carbon: the higher the carbon content, the higher the hardness of steel, but the worse its plasticity and toughness

yGillard melenaAre there many welded types of mesh produced? According to the welding type and overall improvement, the difference between the reinforcement mesh and the welded mesh is not particularly large. It is still due to the scattered quality of the southern city. From the perspective of development to the longitudinal and transverse interleaving devices of the reinforcement mesh, the bound or welded mesh has better application quality.

Since the s, with the rapid development trend of high-quality hot strip mill production and the development of electric welding and testing technology, the welding quality has been continuously improved, specifications and models of welded steel pipes are increasing, and seamless pipes have been replaced in more and more industries. Welded steel pipes are divided into straight seam welded pipes and spiral welded pipes according to the way of welding. Classified by production mode: classified by processing technology - electric arc welded pipe, resistor welded pipe, (high frequency, low frequency) gas welded pipe, furnace welded pipe.
