Stainless steel pipe/tube has high strength, strong corrosion resistance, good toughness, excellent vibration and shock resistance, and it is not brittle at low temperature. In the process of water delivery, it can ensure the purity of water quality.
Thin-walled stainless steel pipe has the following advantages: excellent mechanical properties, excellent wear resistance, good safety and health performance, good temperature resistance, good thermal insulation performance, smooth inner wall, low water resistance and 100% recyclable.
The following is a specific introduction to the role and advantages of thin-walled stainless steel pipes.
Chromium reacts with oxygen and oxidant in thin-walled stainless steel pipes and produces a passivation effect. A thin and tough dense passivation film Cr2O3 is formed on the surface of the steel pipe, which plays a protective role in corrosion resistance.
If stainless steel pipes and fittings are treated by impurity removal, pickling and passivation, the thickness of Cr2O3 generated can be increased, and the uniformity of compactness will be enhanced. By polishing of stainless steel pipes and fittings, not only can surface defects can be eliminated, but also the passivation film will be more delicate and dense, so as to reduce the probability of pitting corrosion. At the same time, the inner wall of the pipe is smooth and smooth, and friction is low, which further improves the hydraulic performance of the pipe and saves the consumption.
Uses and functions
Stainless steel pipe is safe and reliable, hygienic and economical. The thin-walled of the pipe and the development of new reliable, simple and convenient connection methods make it have more and more advantageous compared to other pipe materials.
Galvanized steel pipe, as a common pipe material, is easy to corrode. Under the influence of relevant national policies, galvanized steel pipes will gradually be withdrawn. Plastic pipes, composite pipes and copper pipes have become the common pipe materials of pipeline systems. However, in many cases, the stainless steel pipe has more advantages, especially the thin-walled stainless steel pipe with wall thickness of 0.6-1.2mm in high-quality drinking water system, hot water system and water supply systems.
Advantages of thin-walled stainless steel pipes
Thin-walled stainless steel pipe has the following outstanding advantages: excellent mechanical properties, excellent wear resistance, good safety and health performance, good temperature resistance, good thermal insulation performance, smooth inner wall, small water resistance, beautiful appearance, clean, fashionable, 100% recyclable, conducive to saving water resources, wide range of use, long service life, low comprehensive cost, etc.
What is Stainless Steel Coil?
Stainless steel is initially produced in slabs, which are then put through a conversion process using a Z mill, which converts the slab into coil prior to further rolling. These wide coils are typically made at around 1250mm (sometimes a little wider) and are known as 'mill edge coils'.
These wide stainless steel coils are further processed using a range of manufacturing techniques such as slitting, where the wide coil is slit into a multitude of strands; this is where much of the confusion around the terminology comes in. After slitting, the stainless steel forms a batch of coils taken from the mother coil and these are referred to by many different names, including strip coils, slit coils, banding or simply strips.
The way coils are wound can result in different names being applied to them. The most common type is known as a 'pancake coil', named after the way the coil looks when laid flat; 'ribbon wound' is another name for this method of coiling. Another type of winding is 'traverse' or 'Oscillated' , also known as 'bobbin wound' or 'spool' due to the fact that it looks like a bobbin of cotton sometimes these can be physically wound onto a plastic spool. Producing coil in this way allows much larger coils to be produced, resulting in improved stability and better production yields.
Nickel Alloy Material
About 60% of the nickel in the world ends up as a component of stainless steel. It is selected because of its strength, toughness, and resistance to corrosion. Duplex stainless steels typically contain about 5% nickel, austenitics around 10% nickel, and the super austenitics over 20%. Heat resistant grades often contain over 35% nickel. Nickel-based alloys generally contain 50% nickel or more.
Nickel Alloy Material Properties
In addition to a majority nickel content, these materials and may contain significant amounts of chromium and molybdenum. Nickel based metals were developed to provide greater strength at high temperatures, and greater corrosion resistance than could be obtained from iron and steel. They are significantly more expensive than ferrous metals; but because of their long life, nickel alloys may be the most cost-effective long term material selection.
Special nickel based alloys are widely used for their corrosion resistance and properties at dramatically elevated temperature. Whenever unusually severe conditions are expected one could consider these alloys because of their unique resistance properties. Each of these alloys is balanced with nickel, chromium, molybdenum, and other elements.
