Square flange Ø 40 mm pipe aperture
Solid twin hole flanges made of 304 AISI stainless steel. Extra strong and solid version to build compact and gas-tight connections. To take in the regarding pipe diameter, the central hole intake is constructed with a bore tolerance, which effects easy fitting, fixing and further processing. The flange plates can be mounted directly to elbow pipes, ordinary pipes or assemblies of any kind and form and allow you flexible construction.
Pipe aperture: 40 mm
Material thickness: 8 mm
Outside dimensions: 69x69 mm

Square Flanges Key Features:

• Can be attached to the pipe without welding (sometimes an additional seal weld is used as well)
• Ideal for higher pressure and temperature applications for small pipe sizes
• Not recommended for larger loads, especially when subjected to higher torque

NOTE: This flange is referred to as either threaded or screwed. It is used to connect other threaded components in low pressure, non-critical applications. No welding is required.

Standards: ANSI, AS2129, JIS, DIN, EN-1092-1, BS10, BS4504 etc

Nominal Pressure: PN0.25-PN42, 150LB-900LB, 5K--30K.

Nominal Diameter: DN10A-DN600A, NPS:3/8"-24".

Square Flanges Materials: Carbon steel, stainless steel and alloy steel.

Printing: Carbon steel and alloy steel with yellow print, black print, oil or zinc.

Square Flanges Packing: Plywooden case.

Payment terms: both L/C at sight and T/T before shipment.

* We can also manufacture special application flanges and forgings that customers require.
