What Are The Types Of Stainless Steel Pipe Fittings?
Stainless steel pipe fitting is designed to connect and influence the flow of media in the system. These pipe fittings are designed having different specifications. Elbows, tees, reducer, cross, coupling, unions, adaptors, olets, caps, and valves are the common type of pipe fittings.
Is Ut Testing Possible On ASTM A403 SS Elbow?
The ultrasonic testing makes an ideal method for testing the ASTM A403 SS elbow to check for its strength and integrity.
Cost Difference Of Stainless Steel Fittings In India And Singapore
The cost of stainless steel fittings is dependent on the size, thickness, grade, and type of fitting. The cost of a stainless steel fitting in India is $2.91 per kg, while the cost of a stainless steel fitting in Singapore is $3.2 per kg.
Why Choose Stainless Steel Forged Fittings For Seawater Service?
The stainless steel forged fittings are designed with outstanding chemical composition. This allows the fittings to have excellent corrosion and oxidation resistance that commonly affects items in seawater. The fittings showcase good strength and have resistance to high and low temperatures, making them a viable option in seawater. Apart from this, they have good strength and durability for long periods.
What Are The Difference Between SS Tee And Stainless Steel Reducer
The SS tee and reducer are two of the common fittings in the industry. A stainless steel tee is designed with 3 openings shaped in the form of a T. These tees allow for flow to take place across 2 channels with one inlet section. A SS reducer on the contrary is fitting that connects piping equipment of dissimilar sizes efficiently. These versatile fittings create a gradual drop in pressure and can be part of different fittings.
