Pressed flanges: the best option for pipe assembly
A very good solution for the creation of stainless steel pipes and manifold involves the use of free sliding flanges in order to avoid the orientation of the bolt holes that happens for flanges welded by means of overlap weld.
The positioning of the valves or components all along the pipe can be oriented by means of the rotation of free flanges until joining them. In particular, pressed flanges – by virtue of their peculiar shape – allow the lightening of the joint. This results in a variety of advantages both in terms of lifting the pipe and in terms of price (due to the lower weight of the flanges).
Pressed flanges are created by moulding metal sheets with a hydraulic press. After a series of steps, the sheets get their final forms, i.e. the one showed in their respective product pages. The thickness of the metal sheets used increases progressively as the nominal dimension (DN) increases.
Pressed flanges make use of the same welding collars (EN1092-1 TYPE 33 standard) usually used with free aluminium flanges and EN1092-1 TYPE 01A flat sliding flanges.
In our stock you can find pressed flanges for collars following ISO dimensions with PN 16 and a DN ranging from 15 to 200 and flanges with PN 10 and a DN ranging from 200 to 500.
Laboratory tests proved that the peculiar feature of pressed flanges is the optimal coupling with the sealing gasket interposed between the collars; the right tightening of bolts allows a homogeneous gasket sealing resulting from the uniform pressure all along the flanges’ diameter.
For all these reasons, pressed flanges are the best option when it comes to piping that is pre-assembled in the workshop and assembled in the construction site.
Polyethylene (PE) vs Polypropylene (PP)
PE vs. PP
When it comes to which is the best for your application, plastics can often seem complicated and confusing. We all know that no two types of packaging are created alike, and that means that different varieties of plastic and poly materials are needed for different applications. Below, we're covering two of the most common types of plastic — polyethylene (PE) vs. polypropylene (PP) — and the key differences between them.
Polyethylene (PE)
Polyethylene (PE) plastic is flexible, durable, and tear-resistant. These three characteristics are each a necessity when you need to packaging heavy-duty items within your poly bags. That means that industrial companies often utilize polyethylene storage bags for large, heavy items, such as industrial machining parts.
A polypropylene bag is high clarity and crystal clear in order to enhance the image of whatever product is inside. This PP bag offers a highly protective barrier against both moisture and vapors. These poly bags delay evaporation and dehydration to preserve the freshness and taste of packaged foods. Generally, PP plastics are stronger, clearer, and more expensive than their PE plastic counterparts. Polypropylene bags are great for the following industries — food, electronics and electronics manufacturing, hospitals, agriculture, and more.
Stainless steel is one of the most popular metals used today. This metal scores over several other metals due to its physical properties including good corrosion resistance, durability, etc. Various types of industrial, commercial, and residential items are created using this metal. Stainless steel pipes are one of the most popular products created out of this metal. These pipes are supported by certain accessories which are also made from stainless steel. Stainless steel flanges are one such accessory used to support stainless steel pipes. There are a vast variety of flanges available for purchase. This post discusses eight important types of flanges that you should know about.
The following are the top 8 stainless steel flanges used in stainless steel pipelines:
What is The Radiator?
The radiators are heat exchangers used to transfer thermal energy from one medium to another for the purpose of cooling and heating.
A radiator is a device consisting of a large amount of cooling surface which contains large amounts of air so that it spreads through the water to cool efficiently.
The radiator has a wide range of application in automobile industries there are mainly used to cool the internal combustion engine in the automobile. They also used in piston-engined aircraft, Railway, locomotives, motorcycles, stationary generating plants and other places where such engines are used.
Radiators are classified according to the direction of the water flow through them. In some, the water flows from top to bottom-down flow type radiator. In other, the water flows horizontally from an input tank on one side to another tank on the other side-cross flow type radiator.
Radiators are usually made of copper and brass because of their high heat conductivity. The various sections of the radiators are almost completely joined by soldering.
Types of Radiator
There are two basic types of radiator
In tubular type core, the upper and lower tanks are connected by a series of tubes through which water passes. Fins are placed around the tubes to improve heat transfer. Air passes around the outside of the tubes, between the fins, absorbing heat from the water in passing.
In a tubular radiator, because the water passes through all the tubes, if one tube becomes clogged, the cooling effect of the entire tube is lost. In a cellular. radiator, the clogging of any passage results in a loss but of a small part of the total cooling surface.
Cellular Type Core
In cellular type core, air passes through the tubes and the water flows in the spaces between them.
The core is composed of a large number of individual air cells which are surrounded by water. Because of its appearance, the cellular type usually is known as a honeycomb radiator, especially when the cells in front are hexagonal in form.
In a cellular. radiator, the clogging of any passage results in a loss but of a small part of the total cooling surface.
How to Choose the Best Food Dehydrator
When you’re in the mood to snack, what do you turn to? If you’re like most Americans, your mind probably flashed to images of potato chips, snack cakes or chocolate bars which, while very tasty, aren’t too healthy to be munching on at regular intervals throughout the day.
For owners of food dehydrators, snacking brings to mind a delicious array of healthier fare all of which are homemade right in your kitchen. A few popular dehydrated options include apple chips, kale chips, sundried tomatoes, banana chips and homemade beef jerky.
Food dehydrators are a relatively small investment that can pay off with significant perks for you and your family. From healthier foods to saving you money, here are a few benefits you should expect after buying a food dehydrator.

- Inert, translucent, and creates a lower static charge
- Prohibits a greater amount of light from entering the bag or film, which helps protect the contents
- Attracts significantly less dirt, dust, or other foreign organic elements
- Soft and pliable
- More resistant to cold temperatures and wear and tear
- Generally less expensive than PP

These poly bags delay evaporation and dehydration to preserve the freshness and taste of packaged foods. Generally, PP plastics are stronger, clearer, and more expensive than their PE plastic counterparts. Polypropylene bags are great for the following industries — food, electronics and electronics manufacturing, hospitals, agriculture, and more.
- More resistant to chemicals, high temperatures, and scratches
- Crystal clear for great product presentation
- Stiff and hard plastic
- Rough surface has the potential to produce scratches
- Outstanding vapor and moisture barrier
- Meets FDA and USDA specifications
- Difficult to break, but not very flexible

This metal scores over several other metals due to its physical properties including good corrosion resistance, durability, etc. Various types of industrial, commercial, and residential items are created using this metal. Stainless steel pipes are one of the most popular products created out of this metal. These pipes are supported by certain accessories which are also made from stainless steel. Stainless steel flanges are one such accessory used to support stainless steel pipes. There are a vast variety of flanges available for purchase. This post discusses eight important types of flanges that you should know about.
The following are the top 8 stainless steel flanges used in stainless steel pipelines:
- Weld Neck Flanges: These flanges are distinguished by their protruding necks. The weld neck flanges have the same bevel and thickness of the pipe. This flange is considered for severe service conditions such as sub-zero or high temperatures and high pressure.
- Slip-On Flanges: These are the most affordable varieties of flanges available for purchase. The slip–on flanges have a slightly larger diameter than the pipe, which makes it easier to slip them over the pipe. These stainless steel flanges are fillet welded to a position and are ideal for low-pressure applications.
- Blind Flanges: The flanges are designed without a bore, and are used to seal vessel openings or piping systems. These flanges are ideal for piping systems or vessels that require regular inspection. The blind flanges can be supplied with or without hubs. This flange can easily handle high stress caused due to internal pressure.
- Threaded Flanges: These types of flanges are used for special applications and can be easily assembled without welding. Stainless steel threaded flanges are compatible with pipes with external threads. The flanges are not recommended for applications where bending stresses, high pressure or high temperatures are involved.
- Lap Joint Flanges: The lap joint flanges are the type of slip-on flanges that are used with stub end fittings. These flanges are ideal for piping systems that require regular inspection and maintenance such as low alloy steel pipes or carbon steel pipes.
- Socket Weld Flanges: The flanges are designed for use on small diameter and high-pressure piping. The socket weld flanges have internal welds which contribute to their durability as well as fatigue strengths. These flanges are used in the chemical processing industry.
- Orifice Flanges: The function of these steel flanges is to provide access to a line for metering liquids or gases. The orifice flanges are installed with orifice plates or flow nozzles.
- Ring–Type Joint Flanges: These flanges are used for high pressure and temperature applications. The ring-type joint flanges feature a groove that can be easily compressed on blind, slip-on or weld neck flange. The flanges help avoid leaks in pipelines where media is transferred at high pressure and high temperature.
