Bright annealing of stainless steel seamless pipes
Bright annealing is a specialized heat treatment process applied to stainless steel seamless pipes to enhance their mechanical properties, surface finish, and corrosion resistance. This process involves heating the stainless steel pipe to a precise temperature, maintaining it for a specific duration, and then cooling it gradually to refine its internal structure. The primary objectives of bright annealing are to eliminate internal stresses from manufacturing, improve the material’s ductility and toughness, enhance surface quality, and optimize cutting performance.

Pressure bearing capacity of boiler tubes
Boiler tubes are steel products with openings at both ends and a hollow structure, characterized by a high length-to-circumference ratio. Based on the production method, they are classified into seamless steel tubes and welded steel tubes. Their specifications are typically expressed in terms of external dimensions (such as outer diameter or side length) and wall thickness. The size range varies widely, from small capillary tubes to large-diameter pipes measuring several meters. As critical components in industrial boiler systems, the pressure-bearing capacity of boiler tubes is directly related to system safety and operational efficiency. So, how much pressure can boiler tubes withstand?

What is 321 stainless steel pipe?
321 stainless steel is an austenitic stainless steel known for its exceptional high-temperature stress rupture strength and creep resistance. Compared to 304 stainless steel, it offers enhanced mechanical properties under high-temperature conditions. Stabilized with titanium (Ti), 321 stainless steel prevents intergranular corrosion when exposed to temperatures ranging from 425-850°C. This makes it an excellent choice for applications requiring oxidation resistance, high strength, and phase stability in high-temperature environments up to 900°C. This article will briefly introduce what is 321 stainless steel pipe.

Can stainless steel welded pipes be made into thick-walled pipes?
Many people mistakenly believe that stainless steel welded pipes are synonymous with thin-walled pipes, assuming that their wall thickness is greatly limited and that thick pipes cannot be produced. This misconception primarily arises from the longstanding emphasis on the ease and cost-effectiveness of manufacturing thin-walled stainless steel welded pipes compared to seamless pipes under the same compressive strength. However, with advancements in technology, stainless steel welded pipes have overcome this limitation, and thick-walled stainless steel welded pipes are now widely used across various industries.
