Product Description:

1Structure of ASTM Standard Stainless Steel Welded Pipe

ASTM Standard Stainless Steel Welded 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, ASTM Standard Stainless Steel Welded Pipe are perceived to be stronger and more reliable. Historically ASTM Standard Stainless Steel Welded Pipe was regarded as withstanding pressure better than other types, and was often more easily available than welded pipe.


2‍‍Main Features of ASTM Standard Stainless Steel Welded Pipe:

• High manufacturing accuracy

• High strength

• Small inertia resistance

• Strong heat dissipation ability

• Good visual effect

• Reasonable price

Q:What's the difference between stainless steel 304 and stainless steel 202?
304 stainless steel is a common stainless steel material, the density of 7.93 g/cm3, the industry is also called 18/8 stainless steel. High temperature resistance of 800 degrees, with good processability, high toughness characteristics, widely used in industry and furniture decoration industry and food and medical industry. The common marking methods in the field are 0Cr18Ni9, SUS304.
Q:Under what circumstances can the stainless steel pipe be welded by argon arc, and under what conditions can the arc welding be used?
The quality of argon arc welding is high, the efficiency is low, the efficiency of SMAW is relatively high, the quality of secondary pipe welding, general thick such as 10mm are TIG welding, welding rod filler cover, if the pipe is thin directly by argon arc welding
Q:Classification, advantages and disadvantages of stainless steel welding
The utility model has the advantages of universal use and easy operation, and is mainly regulated by people, and the welding seam material is an electric welding strip. Manual welding can weld almost all of the material, even outdoors, so it has good adaptability and is usually powered by direct current.Welding, either titanium type electrode, can also be sealed. The titanium electrode is easy to weld, the welding seam is beautiful, and the welding slag is easy to remove. But the drawback is that if you do not use it for a long time, you must bake it again to prevent moisture accumulation.
Q:How thick is the 3 stainless steel tube?
3 thicknesses representing 3 mm wall thickness
Q:Are stainless steel tubes and galvanized steel tubes the same?
Stainless steel management theory, the whole is not rusty, from the table to the material is stainless steel, no surface and internal.
Q:Water and electricity thin wall stainless steel tube 304 material delta 2 what does that mean?
304 is a stainless steel number, 2.9 refers to the pipe wall thickness.
Q:What brand of stainless steel pipe cutting machine is good?
Cut stainless steel tube, choose what brand is good, not the most important, first of all depends on what method to cut the best, the current cutting methods are saw blade, saw blade, laser, plasma, turning tools and so on.
Q:How can the inner walls of stainless steel tubes be polished?
1) (used in polishing the inner surface polishing machine): rod is thrown into the tube to drive the impeller 1000 or homemade abrasive wheel rotating speed, and with the rotation of the polishing pipe itself, while rotating slowly forward throwing rod. Generally speaking, first use the 60#-80# wheel of Chiba or abrasive belt wheel for rough throwing, and then gradually fine throwing with high precision according to the requirement of smoothness. Large size pipe 6, more than the general use of thousands of impeller, small size of the pipe can be made with homemade abrasive belt wheel, you can reduce costs.
Q:SA-179 what kind of material is steel pipe?
SA179 corresponds to China's material is GB8163 10# seamless steel pipe.
Q:What is the difference between stainless steel seamless tube and stainless steel welded pipe?
Stainless steel welded pipe is also a hollow section of steel, but it is welded through the plate into the steel pipe, so there is a welded steel pipe welding gap.
