Astm a53 standard specification covers seamless and welded, black and hot-dipped galvanized nominal (average) wall pipe for coiling, bending, flanging and other special purposes and is suitable for welding.
The steel for both seamless and welded pipe shall be made by one or more of the following processes: open-hearth, electric furnace, or basic-oxygen. The weld seam of electric-resistance welded pipe in grade b shall be heat treated after welding.
A53 pipe comes in three types and two grades
Weight of any length shall not vary more than 10% over and 3.5% under that specified.
Note-nps 4 and smaller-weighed in lots. Larger sizes shall be weighed separately by length.
The unit price on this page is just a general amount, as we produce oem orders, so the exact quatation for casting and machining is up to the drawing.
We sale standard parts, but not only, usually, we will receive a drawing from the customer first, if everything goes well, we will open the tooling(mould), then do a few samples before producing batch orders.
We always cherish the honest operating, double-wins and our respectable customers.
We have immense pleasure in introducing ourselves as one of the leading stockiest, importer, exporter and supplier of high quality stainless steel sheets, plates, coils, round bars, wire, rods, forged pipe fitting like flanges, tee bends, elbows etc.
Precision - stainless steel packed with all metal and atmospheric oxygen for reaction, the formation of oxide film on the surface. Unfortunately, the iron oxide in the form of ordinary carbon steel on oxidation, rust continues to expand, eventually forming holes. You can use paint or oxidation-resistant metal (for example, zinc, nickel and chromium) plating to ensure the
1, ferritic stainless steel. From 12% to 30%. Its corrosion resistance, toughness and can increase the welding with chromium increases the amount of resistance to chloride stress corrosion is superior to other types of stainless steel. 2, austenitic stainless steel. Chromium is more than 18%, still contain 8% of nickel and a small amount of molybdenum, titanium, nitrogen and other elements. Comprehensive performance is good, resistant to a variety of medium corrosion.
3, austenitic ferritic duplex stainless steel. Both austenite and ferrite stainless steel and has the advantages of, superplasticity.
4, martensitic stainless steel. High strength, plasticity and poor weldability.
5, precipitation hardening stainless steel. With good formability and good weldability, high strength materials can be used in the nuclear industry, aviation and aerospace industry.
Components can be divided according to cr (sus400), cr-ni system (sus300), cr-mn-ni (sus200) and the precipitation hardening systems (sus600).
