Project Reference:

For the Steel structure project of Upper part of external
piperack for air separation and gasifying facilities of
460,000 tons MTO (Methanol to Olefins) project in
Duolun, we provide about 4,500 tons steel structure. It
is a heavy chemical indusry of national energy project.

Q:Ask the two grouting steel structure column anchor bolts for what?
But mainly by the anchor bolts to stress. The steel column base connection is hinged and rigid, rigid two pouring pouring depth 100mm, pouring depth two time pouring hinged 50mm in steel structure regulation on the stress problem. Of course I saw just according to make a person views.
Q:Name of steel structure awning
With high strength aluminum alloy material, the joint of column and ceiling is strengthened with galvanized steel structure, so it is more secure and firm. The surface of aluminum alloy is treated by powder electrostatic spraying, and the oxidation resistance is more than 30 years.
Q:What kind of material test is necessary for steel structure engineering?
All materials used, such as various steel plates, steel tubes, H steel, square tubes, etc.. Purlin and color steel plate generally do not do, do bulk insulation cotton.
Q:The steel structure and the concrete building which cost is high
The steel structure is of high cost and the steel content per square of the steel structure is higher than that of the concrete structure.
Q:In the steel structure of steel purlin 160*60*20*2.5 is what mean
Stands for 160mm height, 60mm width, and 2.5mm thickness, and 20mm is the size of two small ears
Q:Steel plate for steel structure, what kind of steel plate is it
To make a steel plate, such a phrase, I think, is a little worse.This word is a relatively large range, according to that there is no special requirements, can use general steel: carbon steel structure can be, such as Q235, Q345, Q235 belong to ordinary carbon steel structure, Q345 is the last name 16Mn, belongs to low alloy series.But if it's special, it can be bridge, steel plate, Q235q, etc.. Q345q and so on.
Q:What does steel structure HW stand for?
H is divided into hot-rolled H steel and welded H steel (H) two, hot-rolled H steel is divided into wide flange, H steel (HW), flange H (HM) and narrow flange H (HN) three.
Q:How can the welds in the steel structure be considered qualified?
The weld quality is divided into 3 grades, such as one or two, three, of which the quality grade of the first grade welds is the highest, and so on:Quality requirements for primary welds shall not include defects such as weld, root contraction, undercut and poor joint.There are no defects such as surface porosity, slag inclusion, cracks and arcing defects in the first and two grade welds.The three grade welds can only meet the quality standards of the above two grades with relatively low appearance.
Q:How to determine the thickness of anticorrosive paint for steel structure?
Test method: check with dry film thickness tester. Each component detection 5, each value is the average of the 3 measuring points are 50mm coating dry film thickness.
Q:Can steel frames and channel steel be welded longer?
Steel frames, door frames and channel steels can be welded longer.
