Corrosion Type of Stainless Steel Pipe

Gap corrosion: in the narrow gap, such as the flange or the connection of the thread, the gap in the passivation layer may be damaged, in the design, should be avoided as far as possible using flanges and threaded connections, to avoid the combined gap. In the welding process, should avoid undercut and so on.

Intergranular corrosion: Intergranular corrosion occurs in the chromium-poor areas, resulting in decreased corrosion resistance, corrosion in the strong acidic environment. Chemical Cargo ship stainless steel carbon content of less than 0.03%, after prolonged heating carbon content increases, and steel surface if subject to oil, grease, paint and paint pollution, prone to intergranular corrosion.
Stress corrosion cracking: it is austenitic stainless steel in the chloride ion, mechanical stress and temperature rise under the action of cracking, in the 60 ° below and the cargo tanks rarely occur stress corrosion cracking. It occurs occasionally in a heating coil (heating a chloride-containing semi-solid oil or exposing it to a seawater ballast tank containing chloride ions).stainless steel sheet supplier
Electrochemical Corrosion: Dissimilar materials may be electrochemically corroded due to electrolyte contact. When carbon steel and stainless steel welding, the active metal carbon steel accelerated corrosion. Under the driving of the electrolysis voltage, the electrolytic current between the two components causes electrochemical corrosion.316 Grade 8K Stainless Steel Plate/Sheet

Precision stainless steel tube sales channels

Channels to create value, which is self-evident. Although vendors understand this truth, but that few suppliers to do so. Most vendors simply need to change the way they think about channels.90 degree stainless steel elbows
First, the supplier has to consider channels to create their own value, but rarely consider precision stainless steel tube channel for customers to create value. The use of agents to talk with precision stainless steel tube plant, they are likely to tell you "agent" is a very attractive channel selection, because they will "change" precision stainless steel tube sales costs. Only after the agency made a business deal, the supplier will pay them. Therefore, the use of agents vendor does not concern fixed-precision stainless steel tube sales costs. But vendors are unlikely to tell you how to precision stainless steel pipe customer experience is like, it is impossible to tell you what is the value of agents to provide the ultimate precision stainless steel tube customers.stainless steel strips manufacturers in china
Similarly, the use of direct sales force or precision stainless steel tube plant owned store vendors told the control advantages of precision stainless steel tube sales operations, but they can not recognize their control may precision stainless steel tube to customer convenience and cost price. This does not mean the value of suppliers Not important. It means that already far enough. Future success requires more consideration value to end users and channel members of both parties.aluminium profile for industry

Sanitary stainless steel tube heat treatment

Sanitary stainless steel tube heat treatment can be divided into two categories, namely, final heat treatment and heat treatment in order to meet sanitary stainless steel tube manufacturing process product performance requirements in between processes.304 stainless steel pipe price
Other products, according to the technical requirements of product standards, sanitary stainless steel pipe commonly used heat treatment process mainly quenching, tempering, annealing and normalizing. For example: in the OCTG casing, tubing, drill pipe, line pipe, etc., according to the grade level of the corresponding normalizing, normalizing plus tempering, quenching and tempering (quenching) process; high-pressure boiler tube , high pressure chemical fertilizer pipe usually normalized, normalized and tempered, quenched and tempered (thick-walled tubes) and austenitic stainless steel sanitary pipe solution treatment; bearing ball sanitary stainless steel tube annealing, etc. .3mm stainless steel sheete
For heat treatment step between cold-rolled, cold-drawn production process sanitary stainless steel tube, usually recrystallization annealing, softening annealing. The aim of eliminating work hardening effect, reduce the hardness and improve ductility in order to facilitate further cold deformation process to be implemented.303 stainless steel magnetic properties
