application of scaffolding pipe (ERW welded pipe)
- Q:What's the difference between a rectangular tube and a rectangular steel tube?
- Rectangular tube is a kind of hollow long strip steel, also known as flat tube, flat square tube or square flat tube (Gu Mingsiyi). A large amount of pipe used to transport fluids, such as petroleum,Natural gas, water, gas, steam, etc., in addition to bending and torsional strength of the same weight is lighter, so it is also widely used in the manufacture of machinery parts and engineering structures. It is also used to produce all kinds of conventional weapons, guns, shells and so on.
- Q:How can galvanized steel tubes be painted on the surface?
- The market is commonly used in alkyd iron red primer, iron red epoxy primer are not suitable for galvanized parts, otherwise it is easy to fall off. It is important to point out that the saponification of the galvanized sheet with alcohol, acid and paint will result in the failure of the coating and the damage of the original zinc coating.
- Q:How to perform nondestructive inspection of steel tubes
- The detection principle is based on the ferromagnetic material is magnetized in a magnetic field, discontinuity materials and products (defects) produce leakage magnetic field, magnetic powder adsorption (or detecting) and appear (or on the instrument display). Therefore, this method can only be used for the inspection of the surface or near surface defects of ferromagnetic materials or products.
- Q:Welded and seamless steel pipe how to distinguish?
- Different price:Because the production process of seamless steel tube is more complex, so the price is more expensive than a seamed steel pipe, and pipe joints mainly adopts steel (steel) two welded, fixed price, the most widely used are.
- Q:Is it good to buy a simple wardrobe or a steel pipe?
- If the home place is big, buy Wooden, good-looking durable, if the place is small, buy cloth, easy to receive, mobile, tidy and cheap.
- 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 does cathodic protection of steel tubes mean?
- Applied current: a macro cell consisting of a protected metal piece and an insoluble auxiliary component. The negative electrode of the battery is connected to the metal to be protected. The power supplies the electrons so that the metal is not corroded by missing points.
- Q:DN80 seamless steel tube, what is the standard thickness?
- Commonly used DN80 seamless steel pipe caliber should be 89mm*4mm.
- Q:What's the difference between round and round tubes?
- Round steel is solid and round tubes are hollow
- Q:Could you tell me what difference between SC galvanized steel pipe and MT wire pipe?
- SC galvanized steel pipe, its pipe wall thickness, generally 20 steel pipe in 2.2-2.8mm. Also, we often refer to tap water galvanized steel pipe.MT wire pipe, its pipe wall is thin, generally 20 steel pipe in 1.5-2.2mm.
All these steel pipes are suitable for the industries of oil, natural gas,ship building,chemical, environmental protection,boiler, water conservancy, electrical industry,steel structure, building and other related fields.
