- Required specifications

- Inquire about price/MOQ

Q:Can the KBG25 steel tube hold 4 six types of cables?
Over five types of cables, the outer cross section is about 24 square millimeters, over six types of network cable for the outer cross section of about 35 square millimeters, so 35*4/490=28.57%, far more than 20%. Therefore, according to the norm, only 3 super six categories can be worn. If the distance is short and the joint is not enough, it can be laid like this, but it does not conform to the construction standard
Q:Fastener type steel pipe scaffold steel pipe wall thickness
The scaffolding steel pipe should be specified with the current national standard "GB/T13793" or "straight seam welded steel pipe welded steel pipe for low pressure liquid delivery" GB/T3091 Q235 ordinary steel pipe; steel pipe steel quality should meet the requirements of current national standard grade Q235 steel "carbon structural steel" in GB/T700
Q:What is PE coated steel pipe? Seek explanation
PE coating on the inner wall of steel pipe steel pipe is covered with a layer of polyethylene plastic polymer, PE, polyethylene (Polyethylene of raised temperature is the abbreviation of resistance English), the scope of application of the general PE pipe water supply pipe to a temperature below 40 DEG C, cannot be used for hot water transmission pipeline.
Q:What does cathodic protection of steel tubes mean?
The corrosion of metals causes great economic losses directly or indirectly. Foreign statistics show that every year due to corrosion and scrap metal materials, equivalent to 20~40% of metal production, the world every year due to corrosion and loss of metal reached more than 1 tons.
Q:Which is more load-bearing, the same thickness of steel pipe and steel bar?
The magnitude of the axial force acting on the steel member is only related to three factors, namely, the strength of the material, the sectional area of A and the longitudinal stability factor of F.
Q:Is the steel frame on each floor supporting formwork (floor) called full scaffolding?
The use of scaffold as its height, when the ceiling height below 3.6M, no matter what the ceiling decoration, decorative scaffolding are calculated
Q:How big is the seamless steel tube of DN50?
This refers to the diameter of the steel pipe is 50 mm, DN50 steel pipe diameter is 60.3 mm, that is, 60.3 * 5 mm steel pipe
Q:What is a tight steel tube?
The tight steel tube is called "galvanized steel pipe with sleeve connection" or "flat pipe of steel metal for electrical installation". JDG. The utility model relates to a novel protective conduit for an electric circuit. The connecting sleeve and the metal accessory are provided with a wire pipeline composed of screw fastening connection technology, and the utility model does not need to do cross grounding, welding and covering, and the appearance is silvery white or yellow.
Q:How to make the steel pipe spray paint is not easy to fall off?
First, clean the surface of the object to be sprayed (pay attention to whether or not to paint off, which is the key):Remove rust stains, oil and so on, when spraying, the nozzle and spray the best distance is 20cm, should be two times forming, first thin spray again, dry, and then spray second times, this is more uniform, and not easy to hang
Q:What is the weight of hot galvanized steel tubes? DN150 4mm wall thickness
DN150 4mm wall thickness welded steel pipe theoretical weight is 16.21kg/m, galvanized steel pipe should be multiplied by the weight coefficient after galvanizing, C, DN150, wall thickness of 4mm, C=1.032, DN150, theoretical weight and wall thickness of 4mm galvanized steel is 1.02*16.21=16.7287kg/m = 16.73kg/m.
The company has successively passed ISO9000 quality system, the American Petroleum Institute API, and also earned the environment healthy license, national special equipment manufacturing license.
