Product Description:

1Structure of Seamless Pipe: 

We are company that have many years experience and professional manager team and engineer team and sales team, sure we will provide you high quality of pipe and professioanl service.

Seamless pipe possesses a hollow section and without seam around the strip steel. It is made with solid bar or steel ingot by perforating machine. As the facture process does not include any welding, seamless pipes are considered to be stronger and more durable. Generally speaking, seamless pipe has better pressure resistance and security than other classifications, and was usually more easily available than welded pipe.

Q:Seamless steel pipe is how to do it?
Round tube has some limitations, such as in the plane bending conditions, the tube is better than square and rectangular tube bending strength, and some agricultural machinery skeleton, steel, wood furniture, commonly used square, rectangular tube. According to different purposes, other sections of special-shaped steel pipe are needed.
Q:Where is a steel pipe casing usually used?
A straight tube of carbon steel sheathed on pipes and tubes and threading tubes to protect the joints from damage by electric welding. The purpose is to protect the wires and cables.
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:Material of welded steel pipe
GB/T3091-1993 (galvanized steel pipe for low pressure fluid delivery). Mainly used to transport water, gas, air, oil and heating, hot water or steam, etc. generally lower pressure fluid and other use tube. Its representative material is Q235 grade a steel.
Q:What is the difference between seamless steel pipe and welded pipe?
The thicker the diameter, the more commonly the spiral weld. The seamless steel pipe is generally molten state molten steel through the annular slot backlog, and then stretched and other treatment process, so that there is no weld. On the performance, especially the pressure capacity of the steel pipe than ordinary steel has greatly improved, so often used for high voltage equipment.
Q:What is the outer diameter and wall thickness of the welded steel pipe of national standard DN250?
DN250 is the nominal diameter, the outer diameter of the steel pipe is 273mm, the thickness is above 6.5mm.
Q:Is hot dipped plastic pipe steel?
Hot dip plastic composite pipes used in coal mine gas drainage, ventilation system, fire water system, central air conditioning HVAC piping circulating water, industrial water supply and drainage, water supply and drainage life, conveying gas and other gases, power threading, chemical pipelines and water disposal pipe etc..
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:The outer circle of a seamless steel pipe 50 head into the outer circle of the 40 to close
According to the metal processing performance, pipe size, quality requirements, as well as investment and benefits to choose different processing methods and corresponding auxiliary processes. The basic process of cold rolling of cold drawn pipe are: (1) tube feeding, the pipe material for hot-rolled finished or semi-finished tube, pipe extrusion pipe and welded pipe; (2) pipe material preparation, including inspection, bundling, pickling, cleaning, washing, drying, neutralization, grease and so on; (3) cold processing (cold or cold); (4) finished finishing finished including heat treatment, straightening, sampling, end cutting, inspection (manual inspection and various testing), pressure test, oiling, packaging and warehousing etc.. Different products are refined and the content varies.
Q:DN150 welded steel tubes one meter multiple
The theoretical weight table of welded steel pipe (Kg) can be checked, and the outer diameter and wall thickness can be measured according to the formula.For example: DN150 welded steel pipe, diameter 165mm, thickness 4.5mm, weight kg per meter.Welded steel pipe theoretical weight (Kg/m) = (165-4.5) * 4.5 * 0.02466=17.81Kg
