What is a Screwed Flange?

Threaded flanges are also known as screwed flanges and are similar to slip-on flanges, but the bore is threaded to enable assembling without welding. Screwed pipe flanges are just like to slip-on pipe flanges that are used with pipes that have external threads. It is used where small diameter and high pressure is required. These flanges are available in all materials, specifications, sizes and grades. Screwed Flange is used to connect other components in non-critical applications, low-pressure in which no welding is required. Screwed pipe flanges are similar to slip-on pipe flanges except the bore of screwed pipe flange has tapered threads. Screwed pipe flanges are used with pipes that have external threads.

Inspection & Testing of Screwed Flanges

• Mechanical Testing Such as Tensile of Area, Hardness Test, Positive Material Identification – PMI Testing, Flattening Test, Micro and Macro Test, Pitting Resistance Test, Flaring Test, Intergranular Corrosion (IGC) Test.

Metline is a large producer of various type of flanges such as Weld-neck, Slip-on, Socket-weld, Lap-joint, Screwed, Blind and Threaded Types. We produce and forge screwed flanges to specifications of ASME B16.5, ASME B16.47, ASME B16.48, BS EN 1092, BS 4504, API-605, API-590, MSSSP44, DIN 2632 to 2638, DIN 2576, 2642, 2527, 2566. At Metline, screwed flanges cover a full range of pressure ratings of these specifications (150 – 2500 psi for ASME & PN6-PN400 for DIN/EN flanges). We also specialize in producing non-standard screwed flanges upto a diameter of 4500 mm.

Materials:

A flange is a method of connecting pipes, valves, pumps and other equipment to form a piping system. It also provides easy access for cleaning, inspection or modification. Flanges are usually welded or screwed. Flange joints are made by bolting together two flanges with a gasket between them to provide a seal. Flanges are commonly used to connect valves into pipework making it easier for removal and maintenance. There are many common flange standards and flanges within the same standard can either be flat (commonly cast iron, ductile iron) or raised face (commonly cast steel and stainless steel).

Metline Industries is one of the prominent supplier, manufacturer and exporter of screwed flanges in India. Our manufacturing process for flanges includes an adequate heat treatment and the examination of chemical and mechanical properties. We have CNC machines as well as conventional lathe machines for machining and processing various types of flanges. The benefit of these pipe flanges is that it can be attached without welding. Screwed pipe flanges are often used for small diameter, high pressure requirements.
