GB13296-91 Stainless Steel Pipe UNS S31008 With Polishing

GB13296-91 Stainless steel pipe description

GB13296-91 is a Chinese national standard that specifies the requirements for seamless stainless steel tubes for boilers and heat exchangers. Here is a description of GB13296-91 stainless steel pipes:

1. Seamless construction: GB13296-91 stainless steel pipes are manufactured using a seamless process, which means they are formed from a single piece of stainless steel without any welded joints. This seamless construction provides enhanced strength, durability, and resistance to leakage.

2. Stainless steel grades: GB13296-91 covers a range of stainless steel grades suitable for boiler and heat exchanger applications. The specific stainless steel grades included in the standard are typically indicated by their corresponding Chinese grade designations, such as 0Cr18Ni9 (equivalent to AISI 304) and 1Cr18Ni9Ti (equivalent to AISI 321).

3. Dimensions and tolerances: The standard specifies the dimensions and tolerances for GB13296-91 stainless steel pipes, including outer diameter, wall thickness, length, straightness, and ovality. These specifications ensure the pipes meet the required dimensional standards and can be properly installed and connected.

4. Heat treatment: GB13296-91 may include specific requirements for heat treatment processes, such as annealing or solution treatment, to achieve the desired mechanical properties and improve the corrosion resistance of the stainless steel pipes.

5. Application: GB13296-91 stainless steel pipes are primarily used in boiler and heat exchanger systems where high-temperature and corrosion-resistant properties are essential. These pipes are designed to withstand elevated temperatures, high pressures, and corrosive environments commonly encountered in such applications.

It is important to note that GB13296-91 is an older Chinese standard, and there may be more recent versions or alternative international standards available that provide updated specifications for seamless stainless steel pipes. It is advisable to consult the latest applicable standards or work with reputable manufacturers or suppliers to ensure compliance with current industry requirements.

GB13296-91 Stainless steel pipe features

According to different uses, the requirements for various properties of stainless steel pipes are different, such as acid and alkali corrosion resistance, intergranular corrosion resistance and stress corrosion cracking performance, pitting resistance, climate corrosion resistance, high temperature and oxidation resistance. For use in high temperature environment, it is also required to have satisfactory high temperature persistent strength, durable plasticity, creep resistance and aging stability.

Stainless steel pipe is mainly used for auxiliary exchanger pipe, water heater pipe, main pipe, cooling water pipe and other pipes. Electricity, as the basis of national economic development, national economy and people's livelihood. The inner wall of the stainless steel pipe is smooth, the water transmission resistance is small, can withstand the erosion of high water flow rate, after solution treatment, the mechanical properties of the pipe and the matrix, the corrosion resistance is basically the same, the performance is excellent, and it is widely used in heaters, boilers, heat exchangers, condensers.

Seamless stainless steel pipe production process

China's production of seamless stainless steel pipes is mainly concentrated in Inner Mongolia Baotou Steel, Shanghai Five Steel (Group) Co., LTD., Great Wall Special Steel Co., LTD., Dalian Steel Plant, Fushun Steel Plant, Daye Special Steel Co., LTD., Chengdu Seamless Steel Plant, although the specific process equipment of each production facility is different. However, its production process is mainly divided into hot-rolled seamless stainless steel pipe production process, cold-working seamless stainless steel pipe production process and hot-extruded seamless stainless steel pipe production process.
