Product Description:

 

1Structure of Seamless steel tubes for the United States and the United Kingdom standards

 Seamless steel pipe has a hollow section, a large number of pipes used for conveying fluid, such as oil, natural gas, gas, water and some solid materials, etc Seamless pipe is formed by drawing a solid billet over a piercing rod to create the hollow shell. As the manufacturing process does not include any welding, seamless pipes are perceived to be stronger and more reliable.

Q:What is the single length of galvanized steel pipe?
Hot dip galvanized steel pipe is widely used in fire, power and highway.
Q:25 of the steel pipe with 6 in charge of what is the difference?
25 of the steel pipe with 6 in charge of the difference:25 of the steel pipe refers to the DN25 tube, the outer diameter of 25mm; 6, in charge of refers to DN20 steel pipe, the outer diameter is 20mm.
Q:How to perform nondestructive inspection of steel tubes
Including fluorescence, coloring two kinds. Because of its simple equipment and convenient operation, it is an effective method to check the surface defect of magnetic particle inspection. It is mainly used for surface defect inspection of non-magnetic materials.
Q:Stainless steel tube, also known as why tube?
The longitudinal section can be divided into equal section tube and variable cross section tubeThe variable section tube has a conical tube, a stepped tube and a periodically cross section pipe, etc.
Q:What is the diameter of the steel tube DN20?
Usually the nominal diameter is nominal for cast iron pipe, steel pipe joints, concrete pipe pipe, seamless steel pipe does not use this notation (with diameter * wall thickness). With nominal diameter pipeline accessories, meaning with tube.
Q:Is the diameter of the steel tube indicated by the outer diameter by the wall thickness or by the inside diameter by the wall thickness?
Seamless steel pipe specifications are: outer diameter, wall thickness, material. Three of these reflect its main features.Welding pipe specifications are: nominal diameter (internal diameter), galvanized or non plated
Q:Difference and application of seamless hot rolled pipe and cold drawn pipe in seamless steel tube
The general production of hot-rolled seamless steel pipe in the automatic tube rolling mill. Solid billet after inspection and clearance of surface defects, cut into required length, in the tube hole end surface of centering, then sent to a heating furnace, in punch in punch. While continuing to rotate and advance, in the roll and immediate action, tube gradually form a cavity, called capillary. Sent to the automatic tube rolling mill on rolling. Finally after all the entire thickness, sizing machine sizing, achieve specifications. Using continuous pipe mill production of hot-rolled seamless steel tube is advanced.1.2, in order to obtain smaller size and better quality of seamless tube, cold rolling, cold drawing must be used or combined method of cold rolling. Usually in two roller mill, rolling ring groove tapered plug pipe in variable cross section circular slot and the composition. Drawing is usually in single or double 0.100T chain drawbench.1.3, the extrusion method will soon heat the tube blank in the closed extrusion cylinder, the perforation bar and extrusion rod movement, so that extrusion parts from the smaller die hole extrusion. This method can produce smaller diameter steel pipe
Q:Fastener type steel pipe scaffold external parts name
Steel pipeScaffold steel pipe should adopt outer diameter 48mm and wall thickness 3.5mm welded steel pipe, also can use outer diameter 51mm and wall thickness 3.1mm welded steel pipe. For horizontal horizontal rods, the maximum length of steel pipe shall not be greater than 2m; other poles shall not be greater than 6.5m, and the maximum mass of each steel tube shall not exceed 25kg, so as to be suitable for manual handling.
Q:Where is a steel pipe casing usually used?
Classification of casing: rigid casing, flexible waterproof sleeve, steel pipe sleeve and iron sheet bushing, etc..
Q:How seamless steel tube is formed?
Seamless steel tubes are formed by cold drawing and hot rolling.
