Product Description:

1、Structure of Carton Seamless standard pipe ASTM A53: 

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. Historically seamless pipe was regarded as withstanding pressure better than other types, and was often more easily available than welded pipe.

 

2、‍‍Main Features of Carton Seamless standard pipe ASTM A53:

• Small inertia resistance

• Strong heat dissipation ability

• Good visual effect

• Reasonable price 

• High manufacturing accuracy

• High strength

- Inquire about price/MOQ

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:What is the meaning of "DN" and "Phi" in the dimensioning of steel pipe diameter and how to apply the mark?
DN represents the path of the tube". Fair represents diameter. Path is the diameter of the fluid through which it should be inside. The diameter may be the outer diameter or the inner diameter. The diameter is only used when the pipe is used for flow through. Fair as long as the garden can be used. According to the requirements of mechanical drawing fair, DN text notes.
Q:What's the difference between hot dip galvanizing and cold galvanizing? Which kind of galvanizing method is good?
Cold galvanizing refers to the zinc plating, the coating is thinner, corrosion resistance is slightly worse, variable color. Environmental pollution.Hot dip galvanized by molten zinc ingots, the coating thickness can be adjusted, good corrosion resistance, and subsequent passivation, can be used for outdoor rust, long service life, some up to 20 years.
Q:Is steel pipe made of profiles?
According to the shape of the cross-section, the steel is generally divided into profiles, plates, pipes and metal products in four categories.Therefore, the steel pipe belongs to the pipe, not the profile.
Q:ASME seamless tube how to express, what is the form, I did not find on the ASME, thank God!
Seamless steel pipe, welded steel pipe, then its means of expression is: nominal diameter refers to the outer diameter (diameter * wall thickness), the unit is mm. [for example, seamless steel tubes of phi 32 * 3. It means that the nominal diameter (outside diameter) is seamless steel pipe of phi 32mm and wall thickness 3mm.
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:Galvanized steel pipe, PPR pipe, PE pipe, U-PVC pipe and HDPE double wall corrugated pipe and what is the difference between the characteristics of
U-PVC tubes are hard poly vinyl pipes, because they contain chlorine, so they are mainly used in sewer pipes or electrical wiring;HDPE double wall corrugated pipe is a high-density polyethylene pipe, because of its excellent electrical insulation performance, now mainly used for distribution line arrangement.
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:Is there a weld on the outer wall of seamless steel tube?
Seamless steel pipe's inner wall, outer wall, section, cross section can not see the weld seam. Because seamless steel pipe is a molding product, no late roll pressure, welding and other processes. No section, inner wall, outer wall or section, as long as there is weld, it is not seamless steel tube. The inner wall can not see the outer wall of welding seam, but it can be seen that the weld products are fake or polished goods. Some products can not be seen without friction and have weld seams on the outside wall. They are seamless treated steel tubes and are polished goods. The price is much different from the real seamless steel tube. Some bad wounding, confusing concepts, earn illegal profits.
Q:What is the outer diameter of the steel tube?
The diameter of a steel pipe refers to the diameter of the steel pipe. The specifications of the steel tube is normal with diameter (diameter and thickness) said, for example 100MM outer diameter and wall thickness of 5MM tube is marked with 100*5.
