Q:What's the difference between steel pipe and pipe fittings?
Steel: steel pipe is a hollow steel strip, used as pipe conveying fluid, such as oil, gas, water, gas, steam, in addition, the bending and torsional strength of the same, the weight is light, so it is 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 pipe be connected with stainless steel pipe?
Welding methods are used to connect. Because galvanized pipe is in fact carbon steel pipe, so galvanized pipe and stainless steel pipe welding, in fact, carbon steel and stainless steel welding, welding of dissimilar materials.
Q:What type of steel pipe for security windows?
Stainless steel security window generally use 25 square tubes and 19 round tubes! 25/38 tubes and 22 round tubes are also available!
Q:What is the difference between galvanized iron pipe and galvanized steel pipe? Or called different, in fact, is referred to as galvanized pipe?
Just name different, all refers to GB/T 3091-2015 "low pressure fluid transport welding pipe" contained in the galvanized pipe.Galvanized pipe means zinc plated, suitable for water, air, heating, steam and gas and other low pressure fluid conveying straight welded steel pipe, longitudinal submerged arc welding (SAWL) steel pipe and spiral seam submerged arc welding (SAWH) steel pipe.
Q:What's the difference between the fastener type steel pipe scaffold, the floor type steel pipe scaffold and the overhanging type steel pipe scaffold?
It is made up of steel pipe, fastener, base, foot board, safety net and so onSteel pipe rod: generally there are two kinds, an outer diameter 48mm, wall thickness 3.5mm; another kind of outer diameter 51mm, wall thickness 3mm; according to its location and function is different, can be divided into vertical pole, horizontal rod, sweeping rod, etc..Fasteners: fastener is the connection between the steel tube and steel tube, which has three forms, namely the right angle fastener, rotating fastener, butt joint fastener: rectangular fastener for connecting the two vertical pipes, it depends on the friction between the fastener and the steel pipe to transfer load. Swivel fastener: used for connecting two steel tubes intersecting at any angle.
Q:What are the main types of steel pipe ah? How to judge which kind of steel pipe performance is better?
Sort by connectionThe connection way of steel pipe can be divided into: light pipe (pipe end without thread) and wire tube (Guan Duan with thread).The tube can be divided into ordinary tube and end tube.Thickening of the tube can also be divided into: extra thick (with external thread), internal thickening (with internal thread) and inside and outside thickening (with internal and external thread) and other vehicle wire tube.The wire tube can also be divided into ordinary cylinder or taper thread and special thread.In addition, according to user needs, wire tubes are generally equipped with pipe delivery.Plating characteristicsAccording to the characteristics of surface coated steel pipe can be divided into: Clarinet (not coated) and coating tube.The coating tubes include galvanized pipes, aluminium plated tubes, chrome plated pipes, aluminized tubes and other alloy layers.The coating tube has an outer coating tube, an inner coating tube and an inner and outer coating pipe. The commonly used coatings are plastics, epoxy resins, coal tar, epoxy resins, and various glass based anticorrosive coatings. Galvanized pipe is divided into KBG pipe, JDG pipe, threaded pipe, etc.
Q:How to distinguish between steel pipe and spiral pipe material?
Steel pipe according to the pipe material (ie steel) can be divided into: carbon tube and alloy tube, stainless steel tube.Carbon tube can be divided into ordinary carbon steel tube and high quality carbon structure tube.
Q:Can stainless steel pipes spray black paint?
Stainless steel pipes can spray black paint.The stainless steel surface with a layer of smooth surface, so the painting before the need to use corner grinder or iron brush to paint out into hair and then paint. Otherwise, spray paint can not be adhered to the surface of the stainless steel pipe.
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:What is the weight of hot galvanized steel tubes? DN150 4mm wall thickness
GB/T3091-2008: DN150 welded steel pipe, wall thickness of 6mm, the theory of the weight of welded steel pipe 24.02kg/m, galvanized steel pipe should be multiplied by the weight coefficient after galvanizing, C, DN150, wall thickness of 6mm, C=1.02, DN150, theoretical weight and wall thickness of 6mm galvanized steel 1.02*24.02= 24.5kg/m.
