Product Description:

1、Structure of Stainless Steel Seamles Pipe 304 ASTM A312 Description:

Stainless 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 the Stainless Steel Seamles Pipe 304 ASTM A312:


• High manufacturing accuracy

Q:A333gr6 steel pipe and domestic material of the same?
The SA333 standard in ASME (cryogenic seamless and welded nominal steel tubes), so A333-6 is a representation of the United States, followed by many countries.
Q:Can the KBG25 steel tube hold 4 six types of cables?
1 of the six lines of cross-sectional area of about 25 square millimeters, 4 to 100 flat, KBG25 cross-sectional area of about 490100/490=20.4%, just over the specifications, so short distance and less elbow can be worn. However, due to the construction of pipes are generally not standardized, elbow more, and do not use special elbow (site bending), so KBG25 wearing 4, six kinds of cable are more difficult.
Q:How to distinguish seamless pipe and welded pipe?
The way to distinguish seamless pipes and welded pipes is to see if there is weld marks on the port.
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:What is the difference between steel pipe and round steel?
Widely used in the manufacture of structural and mechanical parts, such as oil drilling pipe, automobile transmission shaft, bicycle frame and steel scaffolding used in construction. Making ring parts with steel tubes can improve data application rate, simplify manufacturing process, save data and work hours, such as rolling bearings, rings, Jack sleeves, etc., and have been widely used in steel pipe manufacture.
Q:Material of welded steel pipe
GB/T14980-1994 (large diameter welded pipe for low pressure fluid delivery). Mainly used to transport water, sewage, gas, air, heating, steam and other low-pressure fluid and other uses. Its representative material is Q235 grade a steel.GB/T12770-1991 (stainless steel welded pipe for mechanical structure). Mainly used in machinery, automobiles, bicycles, furniture, hotels and restaurants, decorations and other mechanical parts and structures. Its representative material 0Cr13, 1Cr17, 00Cr19Ni11, 1Cr18Ni9, 0Cr18Ni11Nb and so on.
Q:Are steel tubes and round steel in weight or length when purchased?
It's priced by weight. The cutting process should size to determine the length (otherwise - please specify the weight of the material), the material ration to calculate weight for cost accounting as.
Q:How are steel tubes represented?
If you speak of steel pipe, if it is water. Gas transmission pipe, then it is said: nominal diameter refers to the inner diameter. The units are millimeters or inches. [for example, water pipes with phi 25. It means that the nominal diameter (diameter) is 25mm (or an inch) steel pipe.
Q:Why seamless steel pipe called seamless steel pipe?
Seamless is relative to welded steel pipe, because welded steel pipe is welded with steel strip, seamless steel pipe is made of whole round steel empty, no welding seam.
Q:What steel pipes are buried for outdoor heating pipes? Seamless or welded tube? Are there any rules for specific countries? Can use the seamed tube?
Where outdoor heating pipes are buried, what steel pipe shall be referenced by the 11.1.2 code for installation of outdoor piping?:This chapter applies to the quality inspection and acceptance of the outdoor heating pipe network installation of the plant and the civil building group (residential area) with the saturation steam pressure not greater than 0.7MPa, and the hot water temperature not exceeding 130 degrees celsius.
