Stainless Pipes, Fittings and Flanges: 5 Key Benefits

September 10, 2014 in Pipes Valves and Fittings by

Stainless stell flangesFrom tubing, to cutlery, to appliances, stainless steel is used in many different applications.

This is for good reason, because it has many advantageous properties.

Here are a handful of those properties that make it an excellent choice for pipes, fittings and flanges.

Resistance To Corrosion

The most well-known advantage of stainless pipes and fittings (and of stainless steel in general) is their ability to hold up against corrosion. Read More

The Advantages and Cost of Steel Pipe

August 27, 2014 in Pipe by

Steel pipeSteel is a very popular piping material. Here are some reasons why.

Resistance to Internal and External Pressure

Steel’s high tensile strength, ductility and elasticity give it the ability to withstand severe pressures. This performance advantage is particularly notable in stresses resulting from uneven bedding, misalignment, fluctuations in temperature or abnormal cover. Plus, steel pipes are often able to hold up to severe bending or longitudinal stresses that may cause other materials to fail.

Resistance to Shock and Vibration

Modern traffic can impose jarring and damaging shocks and vibrations on the pipes beneath roadways. In these situations, steel pipes are preferable. Their strength and lack of brittleness means they can withstand the stresses of vibrations much better than some other materials.

Protection Against Corrosion 

Galvanized steel pipes have a zinc coating that allows them to endure corrosive environments. The zinc serves as a ‘sacrificial metal’. It rusts before the steel underneath it, even if the zinc layer is scratched. This allows the functional steel part of the pipe to maintain its integrity for longer.

Wide Range of Joints

A variety of joints are available for steel pipes, from very flexible to very rigid. These include: Read More

Copper Pipes: Types, Sizes and Applications

August 13, 2014 in Pipe by

Copper PipeCopper pipes are popular in plumbing, cooling and heating systems. Here’s some basic information about this reliable, long-lasting material.

Types

There are two types of copper pipes: soft and hard.

Soft copper pipes are annealed to make them soft and flexible, and they can be bent so that they can travel around potential obstacles. Hard copper pipes are not annealed. They’re rigid, so fittings like elbows are needed to change the direction of the fluid flow.

Sizes

In the U.S., copper pipes often fall into one of four categories, based on their wall thicknesses.

Type K has the thickest walls and is often used underground, beneath streets and sidewalks.

Type L is one step down in thickness, and is often used for water supply in both residential and commercial buildings.

Type M is thinner still and also used for water supply.

Type DMW is the thinnest and primarily used in unpressurized applications, like waste lines or drains.

Advantages

Copper pipe offers a number of advantages, including: Read More

Welded Pipe vs. Seamless Pipe

July 23, 2014 in Blog, Pipe by

PipeWelded vs. seamless. It’s a debate that’s been around for a long time, and it’s still going strong today.

So when your next project arrives, what side of the debate will you fall on? Will you choose a welded steel pipe, a welded carbon pipe? Or will you go with one of their seamless counterparts?

Here are some of the advantages of both types of pipes to help you make your decision.

Advantages Of Welded

  • Welded pipes are typically more cost effective than their seamless equivalents.
  • Welded pipes are usually more readily available than seamless. The longer lead time required for seamless pipes can not only make timing problematic, but it also allows more time for the price of the materials to fluctuate. Read More

Industrial Pipe Fittings Standards

July 09, 2014 in Blog, Valves and Fittings by

Industrial pipe fittingsWhen you buy something, you want to be confident that it will perform as you expect.

That’s why standardization systems are so important. They let us know that what we’re getting is what we think we’re getting, and that it won’t let us down.

This is especially crucial when the consequences of a product failing are dire–like in an engineering project.

The piping industry relies on standards. To give you a brief idea of how it works, let’s look at how standards apply to industrial pipe fittings.

What Standards Tell Us

Pipe fitting standards give us information about how fittings were designed, how they were constructed, and how they can be expected to perform. Some of the characteristics that pipe fitting standards cover include: Read More

U.S. Oil Country Tubular Goods Producers Stand Up Against Dumping

June 25, 2014 in Industry Trends, OCTG by

Oil Country Tubular GoodsThese days, the talk of the gas and oil pipe industry is how to prevent domestic jobs from being lost to foreign imports.

Last July, some of the largest steel producers in the country brought a petition to the U.S. Commerce Department claiming that nine foreign countries were ‘dumping’ their oil field pipe goods into the U.S. Dumping occurs when foreign governments subsidize industries within their own countries, which allows companies to export their goods at a very low price, often under the cost of production. This allows them to undercut competitors in countries where their goods arrive.

In February 2014, the Commerce Department made a preliminary ruling requiring duties on imports from eight of those nine countries. However, South Korea, the biggest importer by far, was left off the list.

This omission has dismayed many in the oil country tubular goods industry. Steel plants in Pennsylvania and Texas have been idled in part because of the ruling. And more jobs are potentially at risk.  Read More

Alloy 20 Pipe

June 11, 2014 in Pipe by

Alloy pipeCertain applications require piping systems that can withstand extreme conditions.

Some materials lend themselves to this better than others. And one of those materials is alloy 20 pipe.

Also known as Carpenter 20, alloy 20 is a ‘Super’ alloy developed to hold up to sulfuric acid. Its nickel, chromium, molybdenum and copper components allow it to resist chloride ion stress corrosion cracking and pitting attack. What’s more, it has good mechanical properties and can be fabricated easily.

Applications

As you would expect, alloy 20 pipes are often used in environments where sulfuric acid is present. However, their other beneficial characteristics, like easy fabricability, also make them useful in many other applications. Some of the most common applications include: Read More

FAQ’s About Galvanized Steel Pipes

May 28, 2014 in Pipe by

Galvanized Steel Pipe SuppliersGalvanization involves coating steel, iron or aluminum with a layer of zinc. Although various methods can be used to apply the zinc layer, the most common method is hot-dipping, or fully submerging the metal in a bath of molten zinc. Hot-dipping is usually preferred over other methods because it produces a thicker, more durable zinc layer.

Galvanized materials have a range of uses, including pipes. Galvanized steel pipes are particularly popular for outdoor applications. Here are a few commonly asked questions about galvanized pipes.

How does galvanization protect pipes?

The zinc serves as a sacrificial layer. It will rust before the metal beneath it, keeping the integrity of the pipe intact for much longer than regular pipes. Furthermore, even if the zinc layer is scratched or damaged, it will still protect the metal beneath it.

Are galvanized pipes expensive? Read More
