Slip On Flange

Forged Steel SO Flange | Low-Medium Pressure Piping

A slip on pipe flange slips over pipe ends and gets sealed with inner & outer fillet welds. Equipped with a reinforced hub, hubbed slip on forged steel flange delivers higher rigidity than simple slip on plate flange, serving as an economical pick for steady low and medium pressure piping.

 

As a reliable flange supplier, Pengrun offers a large selection of flanges made from carbon steel, stainless steel, duplex stainless steel, alloy steel, and special steels. We can produce flanges conforming to various international standards, such as ASME/ANSI, EN, DIN, JIS, GOST, GB, etc.

FAQs

What is the difference between slip on flange and plate flat welding flange?

Plate flat welding flanges are inexpensive but fragile, suitable only for low-pressure, ambient-temperature applications; slip-on flanges are slightly more expensive but sturdier and more reliable, making them the economical choice for medium- to high-pressure piping.

What face types do you supply for slip on pipe flange?

We provide FF,RF,RTJ,FM,TG five types face for slip on flange.

What materials can you produce for slip on flange?

We can produce carbon steel,stainless steel,duplex stainless steel,alloy steel and special steel for slip on flanges.

What slip on flange sizes can you produce?

Full slip on flange sizes DN15-DN3000, all pressure classes Class150~Class1500 available.

When should I select slip on flange?

Suitable for medium-to-high pressure (Class 150–1500), medium-to-high temperature, and critical operating conditions (such as in the chemical and power industries).
