The monthly summary of the real estate industry shows that there is a significant positive correlation between the market sales and the long-term trend of the apparent consumption of galvanized pipe， but there will also be a backwardness of the market in a special stage and after the backwardness of the market in stages， there will be a rapid decline in the moving average of the apparent consumption of galvanized pipe， welded steel pipe and so on.
1 Straight seam electric welding steel pipe (yb- is a steel pipe whose weld is longitudinally parallel to the steel pipe. It is usually divided into metric welded steel pipe welded thin-walled pipe， transformer cooling oil pipe， etc.
uNiagara FallsI-beam can only be used for beam while H-beam can be used for load-bearing column of structure.
According to the process，Products Show it is divided into arc welded pipe，Sania3087 seamless pipe priceClassified News resistance welded pipe (high frequency and low frequency)， gas welded pipe and furnace welded pipe.
FFrissiaKeep the combustion supporting gas and use it reasonably to avoid fracture of the welding interface. Problems in the welding of steel wire mesh skeleton composite pipe are common， which should be prevented or solved.
PgSteel transfers heat excellently; Can withstand high temperature; Strong and strong materials; Probably a long time ago. In addition， there is the low cost of metal.
Characteristics and application of galvanized pipe
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.
lDue to the relatively high and narrow section size of ordinary I-beam and light I-beam， the moment of inertia of the two main axes of the section is quite different， which makes it very limited in the scope of application. The use of I-beam shall be selected according to the requirements of design drawings.
U Seamless tube has high elasticity，Products Show can be reused on mechanical equipment， no memory， anti-static.

hSThe development of steel bar mesh is in line with the development of energy-saving economy
Because zinc has excellent ductility and its alloy layer is firmly attached to the steel base， hot-plated parts can be formed by cold stamping， rolling， wire drawing， bending and so on without damaging the coating;
They are not affected by surrounding factors and processes， including corrosion.
Honesty is the foundationh 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.
NThe specification of pass design I-beam is expressed in cm of waist width. For example， the waist width of No. I-beam is. The types of I-beam include hot-rolled ordinary I-beam， light I-beam and wide parallel leg I-beam (H-beam). The waist width of hot-rolled ordinary I-beam in China is ~， expressed as No. ~ No.， and the inclination of inner wall of leg is : The pass system of rolled I-beam includes direct pass system， cross pass system and mixed pass system. In addition， I-beam can also adopt special rolling method.
Galvanized pipe has excellent corrosion resistance
bNiagara Falls It is the trend of the development of steel bar industry to take the road of steel bar welding mesh in steel bar construction.
uPIn order to strengthen the "muscles and bones" of the bridge， the construction party specially paved two layers of reinforcement mesh before pouring cement.
