Stretch punching by steel plate equipment; The main purpose is to be used in the structure of scaffold.
6 It has a thick and dense pure zinc layer covered on the steel surface， which can prevent the steel substrate from touching with any corrosion solution and maintain the steel substrate from corrosion. In general atmosphere， the surface of zinc layer forms a thin and dense zinc oxide layer， which is difficult to dissolve in water， so it plays a certain maintenance effect on steel matrix. If zinc oxide and other components in the atmosphere form insoluble zinc salts， the anti-corrosion effect is more ideal.
gColumbusDue to the unique performance of I-beam，Products Show I-beam has successfully solved the problem of serious equipment wear in many industries.
Hardness of reinforcement construction of reinforced mesh on concrete bridge deck; Including key lime mixing and packaging materials，San Francisco12 price quotation of I-beamNew opportunities for development you need to pay attention to calculating the size of the building， and the calculated specifications must meet the quality standards and construction standards.
LLuanda According to the purpose the welded pipe has general purpose and high temperature and high pressure. The pipe used in the latter is often special alloy steel. The problem of shrinkage cracks in the welding process and the mechanical properties of the pipe in the heat affected zone must be considered and solved， and the mechanical properties of the pipe in the heat affected zone will not be greatly changed due to the influence of welding operation.
UkGalvanized pipes shall be stored in dustproofto keep clean and new . As a professional manufacturer of galvanized pipe， we have produced galvanized pipe products for many years. Welcome friends who need to buy.
General carbon steel wire sleeve (GB / t- is a steel pipe used to protect wires in electrical installation projects such as industrial and civil buildings and installation of machinery and equipment.
Transformer tube: it is used to make transformer heat dissipation tube and other heat exchangers. It is made of general carbon steel. Flattening， flaring， zigzag and hydraulic tests are required. Steel pipes are delivered in fixed length or double length， and there are certain requirements for the tortuosity of steel pipes.
h Direct rolling pass system. The direct rolling pass system refers to the pass system in which the two open legs of the I-beam pass are on the same side of the roll axis at the same time， and the waist is parallel to the roll axis.
DThe pipeline shall be positioned according to the drawing design， and the pipeline support shall be prefabricated according to the site conditions. Hang the wire from the th floor down and fix the support.
EJob descriptionGalvanized pipe has excellent corrosion resistance
pBCutting machine，Products Show electric welding machine， polishing machine， etc
Spiral seam high-frequency welded steel pipe (sy- for pressure fluid transportation is a spiral seam high-frequency welded steel pipe used for pressure fluid transportation， which takes hot-rolled steel strip as pipe blank， often warm spiral forming and high-frequency lap welding method. The steel pipe has strong pressure bearing capacity and good plasticity， which is convenient for welding and processing; After various strict and scientific inspections and tests， the application is safe and reliable， the diameter of steel pipe is large， the transportation efficiency is high， and the investment in laying pipeline can be saved. It is mainly used for laying pipelines for transporting oil，Products Show natural gas， etc.
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.
Product rangeoAccording to the data information display information，San Francisco12 price quotation of I-beamNew opportunities for development there is an inseparable correlation between the annual real estate sales data information and the apparent consumption data information of galvanized pipe. From the consumption surface of the middle and lower reaches of galvanized pipe， decoration design elevator car， handicrafts household appliances and other industries are closely related to the situation of the real estate industry.
KI-beam is divided into ordinary I-beam and light I-beam. The specification of hot rolled ordinary I-beam is -#. The specification of hot-rolled flexible I-beam supplied through agreement between the supplier and the buyer is -#. I-beam is mainly used in building structure， vehicle manufacturing， other industrial structures and fixed panels and cabinets. I-beam is often used together with I-beam.
There shall be no bending at the welded junction， and there shall be no staggered joint during assembly. Electric welding positioning is generally spot welding. After inspection and straightening， the free conversion method shall be used for welding as far as possible.
nColumbus According to the process， it is divided into arc welded pipe，Reinforcement, galvanized pipe, seamless pipe, welded pipe, alloy pipe, I-beam-Shandong Kaiwen metal material Co., Ltd resistance welded pipe (high frequency and low frequency)， gas welded pipe and furnace welded pipe.
iH Simple section steel pipe -- circular steel pipe， square steel pipe， oval steel pipe， hexagonal steel pipe， rhombic steel pipe， octagonal steel pipe， semi-circular steel pipe， oxide and dirt， but also the welded pipe will be affected by abrasive impact and friction， resulting in the average roughness of the welded pipe.
