Catalytic Converters


Catalytic Converters: What to Look for
There are several reasons your catalytic converter may have gone bad: corrosion, physical damage or internal clogging. When replacing your converter, it's best to choose one that will allow you to avoid falling victim to the same problem twice. If your car is very low to the ground, for instance, you'll want to make sure you buy a catalytic converter that has a heavy durable metal exterior.


The best catalytic converters are usually made with stainless steel tubing and a stainless steel body. Stainless steel is ideal for catalytic converters for several reasons. The first reason is that it is highly resistant to rusting. Since catalytic converters are usually mounted underneath your car, they are highly susceptible to corrosion from water and road salts that splash up on the undercarriage of your car.

Stainless steel also happens to be a very strong metal that is resistant to dings and cracks. A catalytic converter made of stainless steel will help you avoid physical damage that can render the converter inoperable. When purchasing a catalytic converter, it's a good idea to consider the kind of weather and roads you will be driving on, and make a choice that's right for your driving situation.

Pipe bending equipment



Pipe bending equipment is an important piece of machinery that is used by a range of industries, from small fabricating shops, to large scale construction companies. This article takes a look at some of the most common types of pipe bending machinery, what each of their benefits are, and the best places you can purchase them from.

Single Axis and Full CNC Mandrel Bending Machines

The mandrel bending machine is available in a variety of models, with additional bending machine options. A specialist will be able to advise you on what the right type of machine is for your needs. Standard CNC models will include:

• Multiple stack bending options
• Electric bend head (servo control)
• Windows based control
• 3D part simulations
• Optional functions EG punching

Additional features can include twin head bending machines that are able to make two bends in one go, section rolling machines, and end forming machines with EG swaging or tapering operations.

Pipe Dream Machinery

Pipe dream is a popular make of pipe bending machinery. The model PD50 electro hydraulic pipe bending machine is available with a range of standard and optional tooling additions. What you choose should ultimately depend on what type of piping the machine is being used on. There are also additional specials which can be incorporated onto the machine.

seamless stainless steel pipe

There are many kind of stainless steel sections with various of dimension of each. This post will show you the some typical section of stainless steel which widely used in our works.


1. Welded wide H flange beam

This section below show the detail dimensions of each stainless steel section in order to understand between manufacturers and customers. I have already make a small report of some well known stainless steel suppliers specialize in supplying stainless steel tube.

About note of this Section:
  • A: Width of flange on top
  • B: Width of flange on bottom
  • H: Height of H flange beam
  • t1: Thickness of vertical stainless flange
  • t2: Thickness of flange top and bottom. Some time the thickness of flange top and bottom is difference
  • This images is lack of thickness of welding between vertical flange with bottom and top flange
