What are the common precautions for purchasing stainless steel elbows and special attention? There are relatively many types of stainless steel products, so we must clearly choose the right stainless steel elbows during the purchase process, and we must also understand many common precautions about stainless steel elbows.

High-pressure vessel flange sight glasses and sandwich flange sight glasses are named high-pressure vessel flange sight glasses in the Ministry of Chemical Industry's standards. Due to the influence of construction technology, this construction method will embed two flat flanges and clamp a layer of glass. This design is often called a flat flange sight glass; because its laminated glass is fixed by a flange, it is also called a sandwich flange sight glass.

The tube sheet is on both sides of flange fastening bolts, they are the same bolts, and the pressure on the gasket on both sides of the tube sheet is the same, and they are under force at same time.

A threaded flange is a type of pipe flange with internal threads on its bore, allowing it to be screwed onto a pipe with corresponding external threads, eliminating the need for welding for connection.

In 2023, Wenzhou Shuangneng Stainless Steel Flange and Pipe Fitting Manufacturer in Zhejiang Wenzhou pioneered a high-demand project, crafting corrosion-resistant stainless steel flanges for offshore oil rigs. Faced with rising industry needs for durable marine components, the team employed advanced forging techniques and rigorous pressure testing, delivering 5,000 units within 8 weeks, ensuring compliance with international safety standards and reinforcing their leadership in precision manufacturing.

In 2023, Saudi Aramco’s Jazan refinery replaced 1,200 carbon steel flanges with 316L stainless steel, cutting maintenance costs by 55% over 18 months. Coastal humidity caused rapid carbon steel corrosion, while 316L’s chloride resistance extended service life from 3 to 15+ years.
