The Safe Ways to Use Scaffolding System and Tubes

In high-rise building construction, every step outside the frame to be paved with bamboo basketry or steel fabric, in addition to deaden 1 m high railing and standing bamboo basketry board. On the outer edge of the scaffold, set up safety set net.

Second, the floor protection measures. Now most of the high-rise buildings are concrete frame constructions, widespread adoption MS pipe scaffolding support steel formwork construction. In order to do the protection of the floor construction, can use floor frame. Guard is equal to the height of the two floors of the building, protecting frame width is equivalent to the length of the building a studio.(floor care on the scaffolding tube can prevent falling to the lateral personnel construction, can also be used as a construction safety channel.)  

Three, floor slanted protective measures Some concrete frame building, caused by a lack of hoisting equipment, inconvenient installation floor frame, using steel formwork support. Preferably in the surrounding buildings, the erection slanted plane, vertical height and construction of building height, the same set-up of ledger, carry on oblique one safety net. (the floor is slanted frame, also can prevent the staff falling to the outside, but in the build-up to pick frame, workers have to switch seat belt) four, socket frame protection measures.

Some high-rise building, using the plug in or the ingate cast-in-place reinforced concrete shear wall construction method, in order to ensure the safety of construction personnel. Tool type socket frame can be used, the height of the socket frame over a layer of floor, can prevent the construction layer surrounding the staff fall outward.

Vietnam steel industry has high growth potential

According to the Viet Nam Steel Association, the country's steel industry has great development potential. Speaking at a seminar titled "Viet Nam's steel industry – rise and fall and development potential" in HCM City on Monday, Dr Nguyen Van Sua the association's vice chairman said that per capita consumption in Viet Nam is 200kg, below the world average of 216kg. he said that "In an industrialised economy, the per capita consumption ranges from 500kg to 600kg."

Difficulties in Wall Thickness Control for Straight Seam Steel Pipe Process

Straight seam steel pipe wall thickness control is a difficult production. At present, the straight seam steel pipe manufacturers to improve the wall thickness in the production of precision uses the methods generally including:

1, Tube heating
Heating to the average to prevent rapid up and down temperature. Each take-off and landing temperature is to maintain a smooth slow, the maximum rise and fall temperature does not exceed 30 ℃.
2, Rolling mill mandrel
Average wall thickness of thick wall tube and solid billet make the probability of mandrel bending deformation significantly reduced, can effectively improve the wall thickness of the precision.
3, The accuracy of mandrel
The outer core of the machining accuracy control in ± 0.1mm, mandrel straightness bias does not exceed 5mm. Welding, the two core rods between the piercing a finishing pin positioning, welding in order to avoid the formation of the total straightness bias is too large.
4, The perfect process
Determing whether the centering roll device in place, adjust the relevant core roller in the middle, open the angle and the size of the initiative of the same opening, the middle of the rolling core in the rolling line.
5, Centering roller
Perfect process is to avoid the center pull thin and wall thickness beyond the control limitations of the state of attack, improve wall thickness accuracy.
6, Perforated mandrel
General choice of perforated mandrel diameter Φ108mm-Φ114mm, wall thickness requirements ≥ 25mm and wall thickness of the average thick-walled tube.
7, Rolling the middle line
Making sure that the middle line of the piercing mill is consistent with the middle line of the piercing trolley to prevent "upper rolling" or "lower rolling", so that the billet sticks to the average force during the piercing.
8, Rolling things
On the wear of the head, guide, roll and other rolling things to be real-time change.
9, Rolling things device
Roller distance, the distance must be in the middle of the rolling line. Guaranteed the distance between the guide and the middle of the roller in the middle of the piercing rolling, the upper and lower roller equal to the left and right lead from the same.

How to Weld for the ERW Steel Pipe in Winter

To ensure that the erw steel pipe in the winter welding perfect follow the following steps:
First, increase the welding current welding, slow down the welding speed, the appropriate increase in the cross-sectional area and length of the weld, if necessary, preheat.
Second, not outside the groove on the base metal to start arc, arc extinction to be filled when the pit.
Third, as far as possible not in low temperature conditions for bending, correction and assembly weldments.
Fourth, preheating before welding, welding process to strictly maintain the interlayer temperature should not be lower than the preheating temperature.
Fifth, the use of low hydrogen or ultra-low hydrogen welding materials.
Six, the entire weld should be finished as far as possible to avoid interruption.
