Exhaust Pipe line(Pre fabrication welding pipe) for Scrubber & EGCS
Smokestack, Stack, Funnel for Scrubber, Scrubber piping
Welding type: TIG Welding
Pressure: Low pressure
Application: Marine industry - Exhaust gas pipeline.
The large exhaust pipe fabricate for this order, using 254SMO grade super stainless steel,
254 SMO is a high-alloy austenitic stainless steel developed for use in seawater and other aggressive chloride-bearing media.
In terms of anti-corrosion, especially in the harsh medium environment (such as sea water, high chloride ion content), it performs well, so the Scrubber exhaust pipe using 254SMO is a very good choice.
It can be seen that the size of the exhaust pipe is very large
2.2 meters in diameter, So it is very difficult to process
The movement of pipe fittings depends on driving, The joint of the elbow is often welded in half a day
It took nearly a week for the welding work alone
Although the production process is difficult, it does not affect the work of our processing technical
They are meticulous in every step of the product processing, ensuring quality and quantity
Finally, in less than half a month, the batch of products were produced and shipped
Deliver a batch of satisfactory products for customers
Compared with ferritic stainless steel and austenitic stainless steel, dual phase stainless steel pipe has good welding performance. It is neither like the welding heat affected zone of ferritic stainless steel, because of the grain coarsening, the plastic toughness is greatly reduced, nor like austenitic stainless steel, it is more sensitive to welding hot cracks.
Due to its special advantages, duplex stainless steel is widely used in petrochemical equipment, seawater and wastewater treatment equipment, Gas Exhaust Pipe line,oil and gas pipelines, paper-making machinery and other industrial fields. In recent years, it has also been used in the field of bridge bearing structure, with a good development prospect.
In duplex stainless steel, ferrite and austenite account for half of each phase, and the content of the least phase may reach 30%.
