What are the quality protection measures for galvanized pipe during welding

MDragasaniReinforcement mesh is manufactured by automatic and intelligent production line under the strict quality control of the factory. Grid size, reinforcement specification and quality are strictly controlled. The longitudinal and transverse bars of the reinforcement mesh form a network structure,Products Show so it has good bonding and anchorage with the concrete,Calgary40Cr tubes en acier sans soudure de petit diamètreLa sortie a établi un nouveau record and the load is evenly distributed, which obviously shows the seismic crack resistance of the reinforced concrete structure.

Tx Ditch cover plate (ditch cover plate) is widely used in municipal roads, garden facilities, residential quarters, schools, stadium pipes and other places.

There are many types of galvanized pipes, mainly including cold plated seamless pipes and hot-plated seamless pipes. But now the previous one is no longer used. The hot-dip seamless tube is still in use. Hot dip galvanized pipe is mainly used for steel pipes with low pressure fluid such as water and gas. When in use, if in normal working environment, the thickness of galvanized layer of hot-dip galvanized seamless steel pipe is up to μ M above,Products Show and it has been used safely for about years. It can be seen that its service life is very long. Of course, when purchasing, we should also find regular manufacturers to order. Only in this way can we achieve this service life. As long as the galvanized pipe is cleaned after pickling, it is basically cleaned in ammonium chloride or zinc chloride aqueous solution or ammonium chloride and zinc chloride mixed aqueous solution tank. In order to ensure the quality, electro galvanizing will not be used. There are also some small enterprises in the market. They will use electro galvanizing in production. In this way, although it is much cheaper in price. However, the quality is very good when used, and it is also easy to have problems.


Generally, you can judge whether it is qualified from the appearance, or whether there are problems such as missing plating or bubbles on the outer wall of the whole square pipe. Only by solving these problems in time can it be judged as qualified and better used.

qPatented manufacturing process of I-beam: I-beam has become a new industrial standard for wear-resistant materials


Fsafety requirements Simple section steel pipe -- circular steel pipe,Products Show square steel pipe, oval steel pipe,Calgary40Cr tubes en acier sans soudure de petit diamètreLa sortie a établi un nouveau record triangular steel pipe, rhombic steel pipe, octagonal steel pipe, semi-circular steel pipe, others.

hP Welded steel mesh, a new form of reinforcement, is especially suitable for large-area concrete engineering.

The electric welding reinforcement mesh can reduce the damage and consumption to the reinforcement processing process. According to statistics, after deducting the steel consumption increased by unit lapping,Reinforcement, galvanized pipe, seamless pipe, welded pipe, alloy pipe, I-beam-Shandong Kaiwen metal material Co., Ltd it can also save about % of the steel. After it is transported to the site according to the construction degree of the project it can be hoisted to the working face. There is no need to set a reinforcement processing site on the site, which saves the site and increases the management level of the site. At the same time, it can also solve the problems of noise pollution caused by straightening reinforcement.


Phosphorus: it can significantly reduce the plasticity and toughness of steel, especially at low temperature. This phenomenon is called cold brittleness. In high-quality steel sulfur and phosphorus should be strictly controlled. On the other hand, low carbon steel contains high sulfur and phosphorus which can make it easy to cut, which is beneficial to improve the machinability of steel

Honesty is the foundationcHigh percentage of metal strength.

YWhether I-section steel is ordinary or light, due to the relatively high and narrow section size, there is a large difference in the moment of inertia between the two main sleeves of the section. Therefore, it can only be directly used for members bent in the plane of their web or form lattice stress members. It is not suitable for axial compression members or members with bending perpendicular to the web plane, which makes it very limited in the scope of application.

Cleaning: first, clean the grease, dust and other substances attached to the surface of the galvanized pipe after cleaning.

cBThe fourth is the welding process method to ensure the strict implementation of the special operation method of galvanized pipe. The welding process includes pre welding groove inspection, control of welding process parameters and operation methods, post welding appearance quality inspection, and post welding nondestructive testing if necessary. Control the welding level and the amount of welding materials at each crossing.

In addition to these, the advantages of galvanized pipe are also reflected in some other aspects. For example, its reliability is also very good. Because the combination of zinc coating and steel is good news for metallurgy, it has become a part of galvanized steel pipe on the steel surface. In this way, the durability of its coating is more reliable. And when the zinc coating forms a special metallurgical structure, this structure can withstand mechanical damage during transportation and use. When in use, it also has the advantages of multiple protection. Because every part of the product can be plated with zinc, even in depressions, sharp corners and hidden places can be protected in many ways. It is very convenient during construction. It really saves time and effort. It is because of so many advantages that the utilization rate of this product is very high. And it can avoid the time required for painting on the site after installation. If you want to purchase on your occasion, remember to go to the manufacturer
