    Stainless Steel Pipes: The Ultimate Guide

    When you choose to buy high quality stainless steel pipe, we need to understand some important points before we start.

    Stainless steel pipe is a high-alloy steel product suitable for various fields and is widely used in power generation, renewable energy, pulp and paper, process piping, food and beverage, oil and gas due to its overall corrosion resistance and machinability , mining, ocean.

    What Are Stainless Steel Pipes?

    Stainless steel tube is a kind of hollow long round steel.Stainless steeltubes are mainly used in piping systems for transporting liquids or gases.
    We manufacture steel pipes from alloy steel containing nickel and chromium, which makes stainless steel corrosion-resistant.
    Stainless steel tubing is oxidation resistant and a low maintenance solution for high temperature and chemical applications. Because stainless steel tubing is easy to clean and sterilize, it is also required for use in food, beverage and pharmaceutical applications.

    How Stainless Steel Pipes Are Made?

    Stainless steel tubes mainly go through 14 production processes: a. Round steel preparation; b. heating; c. Hot rolling perforation; d. Cut the head; e. Pickling; f. Grinding; g. Lubrication; h. Cold-rolled processing; i. Degreasing; j. Solution heat treatment; k. Straightening; l. Cut pipe; m. Pickling; n. Product testing.


    What Are The Advantages of Using Stainless Steel Pipes?

    1.  Stainless steel tubes have good corrosion resistance, which is extended from stainless steel itself in contact with water or in a humid environment for a long time without rusting. Some stainless steel pipes developed by modern technology can be washed by chemical liquids for a long time without rusting. damage occurs;
    2. Stainless steel tube has good ductility, which is its second major advantage, because the structure of stainless steel material can withstand a certain external force, although it will deform to some extent, but generally there will be no brittle failure like cast iron pipe. .
    3.  The stainless steel tube has a long service life, which is why the stainless steel will not easily undergo physical and chemical reactions whether it is buried in the ground or exposed to the air.


    The Difference Between 304 Stainless Steel Pipe and 316 Stainless Steel Pipe

    The density of 304 stainless steel is 7.93g/cm3, and the density of 316 stainless steel is 8.03g/cm3. In essence, there is no obvious difference between the two, and they are both a kind of many stainless steels, which have the characteristics of acid resistance, alkali resistance, easy processing and high toughness.

    First of all, in terms of application, 304 stainless steel tubes are widely used, and they have good corrosion resistance. It can be used for anti-theft windows, stair handrails, guardrails, anti-theft doors, automobile exhaust tubes, medical equipment, etc. On the basis of 304, 316 has added elements of Ni, Cr, and Mo, which have higher density, better corrosion resistance and high temperature resistance than 304, so it is widely used in various industrial fields (seawater equipment, chemistry, dyes , papermaking, oxalic acid, fertilizer and other production equipment).

    Secondly, the chemical composition and performance are compared: the chemical name of 304 stainless steel pipe is: 06Cr19Ni10, and the chemical name of 316 stainless steel pipe is: 06Cr17Ni12Mo2. 06 means the carbon content is lower than 0.08, Cr19 means the chromium content is 19, NI10 means the nickel content is 10 . Among them, the element that determines the rust and corrosion resistance of stainless steel pipes is nickel, and its price is relatively expensive.
    The purity and thickness of 304 and 316 are different. 316 has better corrosion resistance and better rust resistance. So the price will be more expensive.

    What Is The Mill Origin of Your Stainless Steel Tubes?

    Our professional management team sources only high quality stainless steel materials and ensures that all materials we use meet our factory standards.

    Our original factory origin is very famous, such as Taigang, Baowu, Jiugang, Pohang, Outokumpu.

    Only in this way, we can provide high-quality cold-rolled and hot-rolled stainless steel products to global users.
