Paslanmaz Çelik Borunun Flanşı Nasıl Çıkarılır

Stainless steel pipes are widely used in industries such as oil & gaz, kimyasal işleme, su arıtma, marine engineering, ve enerji üretimi. To connect these pipes securely, engineers often rely on flanging—a method that creates a projecting rim (flanş) on the pipe end, allowing it to be bolted to another flanged pipe, vana, or equipment. Many professionals, especially procurement managers and technicians, often ask: How to flange out a stainless steel pipe properly and efficiently?

This article provides a detailed guide on flanging stainless steel pipes, explaining the techniques, teçhizat, avantajlar, and applications of this process.

What Does “Flanging Out” Mean?

Flanging out a pipe refers to forming or attaching a flange at the pipe end so it can be connected to other pipeline components. This can be achieved either by:

Forming the flange directly on the pipe end (mechanical flaring).
Welding a prefabricated flange onto the pipe.

Both methods ensure secure, sızdırmaz, and detachable connections, which are crucial in industrial piping systems.

Why Use Flanges for Stainless Steel Pipes?

Detachable Connections: Easy assembly and disassembly for maintenance.
Leak Prevention: With proper gaskets, flanges provide tight seals.
Çok yönlülük: Suitable for connecting pipes to pumps, vanalar, and tanks.
Standardizasyon: Available in global standards (ANSI, DIN, JIS, EN, vesaire.).
Kuvvet: Withstands high pressure and temperature conditions.

Tools and Equipment for Flanging Stainless Steel Pipes

Pipe Cutting Tools – Saw, cutting wheel, or plasma cutter to prepare pipe ends.
Pipe Flanging Machine – Mechanical or hydraulic tool for forming flanges.
Welding Equipment – For attaching weld neck, bağcıksız, or socket-weld flanges.
Measuring Instruments – Calipers, gauges, and squares to ensure precision.
Protective Gear – Safety glasses, eldivenler, and welding shields.

Methods of Flanging Stainless Steel Pipes

1. Mechanical Flanging (Cold Flaring)

The pipe end is mechanically expanded using a flaring machine.
Common for thin-walled stainless steel tubes.
Produces a rolled edge suitable for light-duty applications.

2. Welding a Flange

A prefabricated flange (bağcıksız, kaynak boynu, kucak eklemi, or socket weld) is welded to the pipe.
Suitable for medium to heavy-duty piping systems.
Provides strong, permanent connections.

3. Hot Forming Flange

Heat is applied to the pipe end, and then the flange shape is pressed out.
Rarely used today due to welding and machining being more efficient.

Step-by-Step Guide: Paslanmaz Çelik Borunun Flanşı Nasıl Çıkarılır

Adım 1: Prepare the Pipe

Cut the stainless steel pipe to the required length.
Ensure the cut is clean and perpendicular.
Remove burrs and sharp edges using a grinder.

Adım 2: Select the Flanging Method

Thin-walled tubes → mechanical flaring.
Industrial pipelines → welding a prefabricated flange.

Adım 3: Position the Flange

For welding, slide the flange over the pipe end.
For forming, place the pipe end into the flaring machine.

Adım 4: Form or Weld the Flange

If flaring: expand the pipe end gradually to form the flange.
If welding: use TIG or MIG welding to attach the flange securely.

Adım 5: Finishing and Inspection

Check flatness and alignment.
Deburr and clean the flange face.
Conduct a leak test if required.

Types of Stainless Steel Flanges Commonly Used

Geçmeli Flanşlar – Kurulumu kolay, welded inside and outside.
Kaynak Boyunlu Flanşlar – Ideal for high-pressure systems, welded at the neck.
Soket Kaynaklı Flanşlar – For small-diameter, yüksek basınçlı borular.
Bindirme Bağlantı Flanşları – Useful when frequent disassembly is required.
Kör flanşlar – Close the end of a pipeline or vessel.
