Stainless Steel Pipes Introduction


Stainless steel seamless steel pipe is a long strip of steel with a hollow section and no joints around it. It is a steel pipe that is resistant to weak corrosive media such as air, steam, and water, and chemically corrosive media such as acid, alkali, and salt. Also known as stainless acid-resistant steel pipe.


First, the thicker the wall thickness of the product, the more economical and practical it is, and the thinner the wall thickness, the higher the processing cost; secondly, the technology of the product determines its limited performance, generally The precision of seamless steel pipe is low: uneven wall thickness, low brightness inside and outside the pipe, high cost of sizing, and there are pits and black spots on the inside and outside that are not easy to remove; third, its detection and shaping must be processed offline. Therefore, it reflects its superiority in terms of high pressure, high strength, and mechanical structural materials.

Stainless steel seamless pipe is a steel pipe that is resistant to weak corrosive media such as air, steam, and water, and chemically corrosive media such as acid, alkali, and salt. Also known as stainless acid-resistant steel pipe.

The corrosion resistance of stainless steel seamless pipes depends on the alloying elements contained in the steel. Chromium is the basic element for stainless steel to obtain corrosion resistance. When the content of chromium in steel reaches about 12%, chromium and oxygen in corrosive medium act to form a thin oxide film (self-passivation film) on the surface of steel. , which can prevent further corrosion of the steel matrix. In addition to chromium, the commonly used alloying elements for stainless steel seamless pipes are nickel, molybdenum, titanium, niobium, copper, nitrogen, etc., to meet the requirements of various uses for the structure and properties of stainless steel.

Stainless steel seamless pipe is a kind of hollow long round steel, which is widely used in petroleum, chemical, medical, food, light industry, mechanical instrumentation and other industrial transportation pipelines and mechanical structural components. In addition, when the bending and torsional strength are the same, the weight is lighter, so it is also widely used in the manufacture of mechanical parts and engineering structures. It is also commonly used to produce various conventional weapons, barrels, shells, etc.


The difference between stainless steel seamless pipe and seamed pipe


1. There are certain differences in the chemical composition of stainless steel seamed pipes and stainless steel seamless pipes.
The steel composition of the production of seamless pipes is only to meet the basic requirements of astm. The steel from which seamed pipes are produced has a chemical composition suitable for welding. For example, silicon, sulfur, manganese, oxygen and the mixture of triangular ferrite and other elements in a certain proportion can form a welding melt that is easy to transfer heat during the welding process, so that all welds can be penetrated. Steel pipes lacking the above chemical components, such as seamless pipes, will cause various unstable elements during the welding process, which are not easy to weld firmly and cannot be welded through.

2. The quality of the welded stainless steel pipe is better controlled than that of the seamless stainless steel pipe.
Since the seamed stainless steel pipe is made of accurate cold-rolled sheet according to the test, all defects are limited to the weld. Seamless tubes are punched from stainless steel billets by punching needles, causing a lot of tearing in the wall thickness created by extrusion. The eddy test shows that the defective rate of the slotted stainless steel pipe is generally smaller than that of the seamless stainless steel pipe. Using ultrasonic testing, the background noise of seamless stainless steel welded pipe is so large that it is difficult to detect its shortcomings. However, the background noise of the seamed stainless steel pipe is very low, and it is easy to find the shortcomings.

3. The quality of seamed stainless steel welded pipe is more precise and easier to control than stainless steel seamless pipe:
The production and manufacturing process of stainless steel seamless pipe is to punch a hole into a stainless steel billet at a temperature of 2200°f. At this high temperature, the tool steel is punched and drawn to become soft and spirally formed from the hole. . In that way the wall thickness of the pipe is uneven and the eccentricity is high. The wall thickness difference of seamless pipes is larger than that of seamed pipes. Because stainless steel slotted tubes are made from precise cold-rolled sheets, the wall thickness tolerances of the slotted tubes are small and the wall thickness is very uniform across the circumference.




Application of stainless steel seamless pipe:


It is widely used as a fluid delivery pipe, such as oil, natural gas, water, gas, steam, etc.

It is used as superheated steam pipe and boiling water pipe in medium and low pressure boilers.

Heating surface of water-tube boilers used to manufacture high pressure and above pressure in high pressure boilers

More widely used in furnace tubes for oil cracking, geological drilling tubes and diamond core drilling tubes, etc.
