- Q:What is an electric welded pipe (EFW)? Seek help！
- Pipe and pipe fittings should be suitable for the gap, usually with micro force insertion is appropriate, the gap is too large or too small will affect the quality of the interface.Check the depth of the plug and slip the spigot into the socket and position correctly.
- Q:What's the difference between hot dip galvanizing and cold galvanizing? Which kind of galvanizing method is good?
- There are two kinds of hot dip galvanizing, zinc plated and non galvanized. The flowers must be hot-dip galvanized, without flowers, similar to galvanized.
- Q:Can the KBG25 steel tube hold 4 six types of cables?
- The specification specifies that the duty ratio of multiple conductors through the pipe laying shall not exceed 20%, and the straight-line distance shall not exceed 30 meters. The distance shall be shortened by the elbow, and the specifications or handbooks can be checked in detail
- Q:SC15 what does galvanized steel pipe look like?
- Ordinary galvanized steel pipe, the outer diameter is 1.5 inches
- Q:There are multiple welded galvanized steel pipe outer diameter 108mm wall thickness 4mm length of 6 meters
- Galvanized steel pipe is divided into cold galvanized steel pipe, hot galvanized steel pipe, cold galvanized steel pipe has been banned, and the latter is also advocated by the state for the moment, can be used. In 60s and 70s, developed countries began to develop new types of pipes, and galvanized pipes were banned. China's Ministry of construction and other four ministries also issued a civilization, indeed from two, 000 years since the galvanized pipe as a water supply pipe, the New District cold water pipe has rarely used galvanized pipe, and some of the hot water pipe is galvanized pipe. Hot dip galvanized steel pipe is widely used in fire, power and highway.
- Q:What does "spiral welded steel pipe" DN325*10 mean?
- Spiral welded steel pipe with nominal diameter of 325mm and wall thickness of 10mm
- 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 the buckling type thin-wall steel pipe? What is a tight set of thin-walled steel tubes? What's the difference between the two?
- The thread of the tightening (JDG) joint is unified with an outer thread, a wall thickness of 1.5mm, and a button (KBG). The thread of the joint is an internal thread, and the wall thickness is 1.0mm. Withholding type joint for the use of the same company and pipe connection to matching products with complete connection clamp buckle. Fastening and pressing type correctly connected and locked after no need to do a cross ground.
- Q:How many fasteners are there in a ton of steel tubes?
- In general, 180-200 fasteners per ton of steel pipe.
- Q:DN150 welded steel tubes one meter multiple
- DN150 welded steel pipe according to the thickness of two specifications: outer diameter 165mm, wall thickness 4.5mm, 17.81Kg per meter weight, wall thickness of 5.5mm, 21.63Kg. per meter weight
