Product Description:

1Structure of  Galvanized welded steel pipe for construction machinery

:

The surface of galvanized steel pipe welded steel pipe of hot dip galvanized layer or. Galvanized can increase the corrosion resistance of the steel tube, prolong service life. Galvanized pipe is widely used, in addition to water, gas, oil and other general low pressure fluid pipelines. It is also used in the petroleum industry, especially for offshore oil field of oil well pipe and oil pipe, chemical, coking equipment of oil heater, condensation cooler, coal run oil exchanger tube, and trestle pile, the mine tunnel support frame tube.

Q:What material is RHS in the steel tube?
SHS stands for thin-walled square steel tubes in the structure and represents the self ignition ceramic composite steel tube in the material
Q:Heating system DN40 and DN32 welded steel pipe how to connect?
As for the flange connection: low pressure pipeline is generally not used in this way, can be divided into threaded flanges and flange welding flange, and the flange connecting pipes of different diameters, only the welded flange to diameter, said in a low pressure pipeline which has low pressure pipe connection make an unnecessary move, this is not much, but there are also people with non the standard flange for connecting different pipe diameter, which is not consistent with the technical specification!
Q:How to perform nondestructive inspection of steel tubes
Radiographic inspection (RT)One of the earliest nondestructive testing methods is widely used in the inspection of internal defects of metals and non-metallic materials and products, with a history of at least 50 years. It has incomparable unique advantages, that is to test the correctness, reliability and intuition of the defects, and the ray film can be used for the analysis of defects and as a quality certificate archive. But this method also has the disadvantages of more complicated equipment and higher cost, and should pay attention to the protection of radiation.
Q:How many meters per ton of steel tube?
General scaffolding tube diameter 40mm, specifications specify wall thickness of 3.5mm, the actual wall thickness of 3.2 - 3.4mm.The theoretical weight per meter is 3.85kg and the wall thickness is 3mm.Hence a ton of steel is about 260m.
Q:Galvanized steel pipe DN100 and SC100
DN is the meaning of "bore", also expressed in water supply and drainageSC is welded steel pipe, generally GB tube, that is, thick walled steel pipe, look at the design requirementsMT refers to the wire tube, usually thin-walled tube, there are KBG and JDG
Q:What connections are there for concrete filled steel tubular column foundations?
Application of double beam connection node usually uses "I" shape columns and steel bracket which is around the construction technology of a modern steel concrete column girder casting formed in the steel pipe outside through the two structures, the bearing pin four axis and four angles on the common components of stress transfer. The construction technology in the application is usually used at both ends of the stress transfer construction mode, through the four steel bracket to the corresponding shear stress, avoid crack width because the node contact produces clear, delayed cracks, improve anti cracking ability of regional nodes.This node model in the connection when the longitudinal reinforcement without through the tube, without bending the construction can be carried out directly, with easy construction technology, construction control difficulty, the economic benefits of construction at the same time, the advantage of low reinforcement to save. In this joint engineering technology, the key pride is to control the stress transfer of steel bracket.
Q:What is a tight steel tube?
The fully enclosed steel tube is called "sleeve connection steel pipe". The English abbreviation is JDG. The sleeve between the pipe and the pipe is fastened by screws. The current specification is the construction and acceptance rules of CECS 120:2007 sleeve steel conduit pipe line
Q:What materials are used in scaffolding pipes?
Safety net with dense green net, safety net of flame retardant standards GB, and safety net of flame retardant performance detection for lighter lit mesh 12 seconds after leaving the fire, flame retardant, continued burning of not more than 4S. The application of 9MM safety net rope, rope, nylon rope woven, each network should be able to withstand the impact of the national standard 1.6KN test.
Q:Fastener type steel pipe scaffold external parts name
Foot board can be made of steel, wood, bamboo and other materials, each quality should not be greater than 30kg. Stamping steel foot board is a kind of commonly used foot board, usually with thick 2mm steel plate pressing, length 2-4m, width 250mm, the surface should be anti-skid measures. Wooden feet can use the thickness of not less than 50mm fir wood or pine production, length 3~4m, width of 200-250mm, both ends should be galvanized steel band two, in order to prevent the wooden foot end of the destruction.
Q:Are there specifications for scaffold steel pipe with 48mm * 3.2mm?
However, there are a variety of non GB steel tubes on the market, mainly in the wall thickness, and are thinner than the national standard requirements, you said that thickness may have, but the thinnest only about 2.6mm-2.7mm.
