There are five main guarantee measures for steel pipe welding. If these five aspects are guaranteed the quality of galvanized pipe can also be guaranteed.

4 Spiral seam submerged arc welded steel pipe (SY- for pressure fluid transportation is a spiral seam steel pipe used for pressure fluid transportation, which takes hot-rolled steel strip coil as pipe blank, often warm spiral forming and welded by double-sided submerged arc welding. The steel pipe has strong pressure bearing capacity and good welding . After various strict scientific inspections and tests, it is safe and reliable to use. The steel pipe has large diameter and high transportation efficiency, and can save the investment in laying pipelines. It is mainly used for transporting oil and natural gas.

Chromic acid solution must be carried out h after the subsequent water cleaning of metallographic structure and austenitic alloy pipe. Chromic acid aqueous solution (mass ratio) is % ~ %, the solution temperature is ~ ℃, and the solution time is min. Then dry.

Characteristics and application of galvanized pipe

RMalo ancetraThe reinforcement mesh is used for embankment protection or for the protection of the whole riverbed and river bank, which is more suitable for the river channel with relatively gentle original bank slope. Taking the design dry water level as the boundary, the upper part is slope protection works and the lower part is foot protection works.

CuAre 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.

Galvanized pipe: the hot-dip galvanized pipe base plate and molten electroplating solution are combined physically and chemically to form a dense corrosion-resistant structure of zinc iron alloy layer. The alloy layer is integrated with the pure zinc layer and the steel pipe substrate. Therefore, it has strong corrosion resistance.

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 the anchorage length of the small reinforcement required by the standard (without transverse reinforcement),Products Show when the beam width is small, the extended reinforcement shall be bent.

tThe section of I-beam has good straight pressure and tensile resistance, but the section size cannot resist torsion because the wing plate is too narrow. On the contrary, H steel has its own advantages and disadvantages.

U Steel pipe with complex section -- unequal hexagonal steel pipe, five petal quincunx steel pipe, double convex steel pipe, double concave steel pipe melon seed steel pipe, conical steel pipe, corrugated steel pipe, watch case steel pipe and others.

NSafety productionWelded pipe refers to the steel pipe with joints on the surface,Products Show which is welded after the steel strip or steel plate is bent and deformed into circular, square and other shapes. The blank used for welded pipe is steel plate or steel strip. How can the steel strip or steel plate be welded together,AjaxASTM a106b tubes sans soudureObjectifs des services and what are the welding skills?

zWIn 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, remember to go to the manufacturer,Reinforcement, galvanized pipe, seamless pipe, welded pipe, alloy pipe, I-beam-Shandong Kaiwen metal material Co., Ltd so that the price will be more favorable.

External steel bonding reinforcement method is a more traditional reinforcement method. The utility model uses an adhesive to paste the steel plate or reinforcement mesh on the cracked part of the wall to achieve the purpose of reinforcement. The commonly used adhesive is usually epoxy resin. This method is simple and fast in construction and has little impact on production and life. Basically, the bearing capacity of the wall can be greatly improved without changing the shape and internal use space of the components. It is mainly applicable to the reinforcement of walls that do not allow to increase the section size of original components, but can greatly increase the section bearing capacity.

Where can I find it?q Carbon: the higher the carbon content, the higher the hardness of steel, but the worse its plasticity and toughness

UAt 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.

Spiral seam submerged arc welded steel pipe for general low-pressure fluid transportation (SY / t- is a submerged arc welded steel pipe for general low-pressure fluid transportation such as water, gas, air and steam, which is made of hot-rolled steel strip coil as pipe blank, often warm spiral forming and double-sided active submerged arc welding or single-sided welding.

aRed deerDuring the construction of building wall, 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.

pKIn 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.

Generally, what are the customer&#;s requirements and standards during acceptance? When the galvanized pipe is accepted, 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.
