Product Description:

1Structure of Seamless Pipe ASTM A106/53: 

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. 

Packing and shipment

Packaged in bundles,as per customers' requirements, it can also bepackagesd as beveled ends, typed marking, black painting, plastic caps protection,woven bags packing

For 20" container the max length is 5.8m; For 40" container the max length is 12m. other options are available based on customer requests. Please discuss when placing orders.

Q:Why is stainless steel magnetic?
There are kinds of stainless steel at room temperature, the organizational structure can be divided into several categories: 1. austenitic: such as 304, 321, 316, 310; 2. martensite or ferrite, such as 430, 420, 410; austenitic is non-magnetic or weak magnetic properties, martensite or ferrite is magnetic. Usually used as a decorative stainless steel pipe,Most of the stainless steel plate is Austenitic 304 stainless steel material, is generally non-magnetic or weakly magnetic, but fluctuations in chemical composition caused by smelting or processing of different magnetic properties may also appear, but this can not be considered to be counterfeit or substandard, what is the reason? The above mentioned austenite is non-magnetic or weakly magnetic, and martensite or ferrite is magnetic, due to melting segregation or improper heat treatment, will cause a small amount of martensite Austenitic 304 stainless steel body or ferrite.
Q:Stainless steel pipes can not be less than the amount of chromium
The chromium content of stainless steel is generally not less than said first why stainless steel tube is not easy to rust 12%-304 stainless steel tube, then why stainless steel will rust stainless steel is not easy to have a great relationship with the composition of stainless steel rust. In addition to iron, stainless steel contains chromium, nickel, aluminum, silicon and so on.
Q:Mechanical properties of stainless steel tubes
The phenomenon of deformation due to external forces increases with time is called creep. At a certain temperature, especially at high temperature, the greater the load, the faster the creep occurs. Under a certain load, the higher the temperature and the longer the time, the greater the possibility of creep. On the contrary, the lower the temperature and the slower the creep rate, the less creep is when the temperature is low to a certain temperature. This minimum temperature varies according to the type of steel. In general, pure iron is at about 330 degrees, while stainless steel has been strengthened by various measures, so the temperature is above 550.
Q:Advantages and disadvantages of PPR lined stainless steel pipe and PPR aluminium plastic pipe
1 、 aluminum plastic composite pipe including lap welding aluminum plastic composite pipe and butt welding aluminum plastic composite pipe, butt welding, the thickness of the aluminum strip and welding process requirements are relatively high.2, the existence of lap welding aluminum layer, increased the modulus of the pipe, and the wall thickness is more thick, installation of pipe is more difficult to bend, need to use more pipe fittings for connection, therefore, field construction is more difficult than PP-R. And the plastic aluminum steady state composite tube must first strip off the outer protective layer, the adhesive layer and the aluminum layer before welding, and then can connect. If the adhesive layer is not clean, it will lead to welding unreliable and leak point.
Q:Mirror stainless steel tube 60*60 how much is one meter?
Stainless steel tube square weight formula: (pipe circumference / 3.14- actual thickness) * actual thickness *0.02491* length, 0.02491 of which is converted by the stainless steel density of a constant.
Q:304 stainless steel will rust it?
Stainless steel is a very thin layer formed on the surface and the stability of the fine solid chromium rich oxide film (protective film), to prevent the infiltration of oxygen atoms, to oxidation, and the ability to obtain anti-corrosion. Once there are some reasons, this film was constantly destroyed, air or liquid oxygen atoms will continue to infiltrate or metal atoms of iron to keep out from the loose formation of iron oxide, the metal surface will be continuously corroded.
Q:Is galvanized steel pipe stainless steel pipe?
Not galvanized pipe, but the surface of the welded pipe galvanized zinc rust protection. The stainless steel pipe is welded by stainless steel band, or made of stainless steel bar punched (seamless pipe). And the two prices are very different
Q:What is the difference between the stainless steel tube and tube rolling
Stainless steel seamless pipe manufacturing process at home is divided into hot and cold drawing tube, two pieces of process what is the difference between the use of the same? Let's make a brief introduction.
Q:What wire is used for welding of 316 stainless steel line?
Quality inspection of welding groove preparation, according to requirements of groove size, accuracy and surface quality stipulated in construction instruction and welding process instruction, groove quality including flatness, perpendicularity and cleanness.1, check the groove processing size (height, angle, edge and blunt edge, etc.) and accuracy isDoes it meet the relevant technical standards?.2, check the groove surface roughness and surface defects (cutting gap, crack,Layer and slag) if beyond the scope of the standard should be allowed to defect, repair treatment, such as surface roughness does not reach the standard, can use abrasive grinding.3. Check the surface cleaning quality of the groove. At least 200mm of the groove face and its sidesShould be clean within the scope, without burr, slag, rust, oil, film and paint and other harmful foreign bodies.4 、 nondestructive inspection of groove surface. For welding process documentation, specify the slopeMaterials such as CY-M steel, Fe-CY-N, high temperature steel and alloy steel shall be examined on the surface for nondestructive testing (such as coloring, etc.), and the defects such as cracks shall be removed.
Q:304 stainless steel tube with the diameter of 25*2-3 is what mean?
304 stainless steel tube with the diameter of 25*2-3 said: material for 304 (the equivalent of the American brand, Chinese numbered S30408 stainless steel or 06Cr19Ni10 stainless steel), diameter (OD) for 25mm, for the seamless steel pipe wall thickness of 2 to 3mm.
