Our process applies a fully fused zinc coating to the exterior surface after seam welding. This is beneficial in that the total circumference of the tube is coated with zinc. This provides an equal amount of protection over the entire surface of the tube including the weld seam. Unlike products manufactured using pre-galvanized materials with a metallized seam, the weld seam does not have the same level of protection as the body of the tube or pipe. It is widely accepted that metallization of the weld seam will fail far more rapidly than the pre-galvanized material. The following graphic illustrates typical performance of various products tested under the ASTM-117B Salt Spray Standard.

Authored by Peter Chifo, Jr. (A segment of this blog was originally published in The Fabricator) Methods for Galvanizing Tubulars and Shapes At present there are four production methods being employed to produce galvanized tubular products. Three of these are well known and only a brief description of each is provided. The fourth continuous process not being as widely known is presented in more detail. Pre-Galvanized Strip with Metallized Weld Seam This method utilizes pre-galvanized strip in lieu of un-coated steel strip. As the zinc coating is melted away at the weld seam during the welding process, a metallized spray is directed over the seam to provide corrosion protection. The inability to provide corrosion protection to the weld seam equal to that of the pre-galvanized strip makes this product susceptible to premature failure and is thereby practical for limited environments and usage. While this process requires minimal capital investment this is typically offset by the high cost of raw material which can be quite unstable due to wide fluctuations in balance of market supply and demand. Electro-Deposition or Electroplating

Our process design of Zinc-Tech™ ILG rapidly heats and cools the tube during application of zinc. A distinct benefit of this process is both higher yield and tensile strength. The following graphic will illustrate a comparison of products manufactured utilizing the Zinc-Tech™ process as compared to products manufactured by the hot dip method.

Authored by Pete Chifo, Jr. ORIGINALLY PUBLISHED IN TUBE & PIPE TECHNOLOGY MAGAZINE This article will inform you of the vast opportunities available to tube producers to expand into rapidly growing, profitable markets through utilization of the inline galvanizing process. While In-Line galvanizing systems have been used for over three decades by a relatively small group of producers, market expansion for its end use products have made the process attractive to a variety of tube producers worldwide. Traditionally the most common finished products for In-Line systems have been electrical conduits and fence tubes. Recent developments in line designs and technologies have enabled a number of new uses which can be manufactured more efficiently and far more cost effective than by other galvanizing processes. To begin, I would like to identify the most common alternative methods of galvanizing tubular products and shapes. They are: Hot Dipped Galvanizing Electroplating Operations Conversion of Pre-Galvanized Strip While admittedly there are a few inherent advantages of each of the preceding methods, their disadvantages far outweigh their value to tube producers. As the technology of these methods are widely known, I will not address the details of these designs. Instead I will present the case of why the In-Line process is far more valuable to the modern-day producer.

A common misconception has been lingering in the galvanizing industry for decades: "The thicker the zinc coating, the better!" - Customer Many manufacturers who are eager to reduce their production cost and the prices for their customers know, a thicker zinc coating does not always result in better product performance. However, it is often difficult to explain this to the customer who often doesn't completely understand why. And, since a handful of end use products do benefit from a thicker coating, selling products with low zinc weight can sometimes become a struggle. So, which is it now? Does zinc coating thickness or zinc weight really matter?

Zinc-Tech™ ILG, In-line galvanizing process is very popular amongst its users due to its vibrant features. Zinc-Tech™ ILG is capable of producing different types of products which adhere to different shapes, sizes, lengths and market segments. Zinc-Tech™ ILG is extensively used to produce tubulars in any size or lengths without having the stress to maintain huge zinc kettles, it also produces electrical conduits with the premium top notch quality which adds to its prime features, usability and increased life. It is also used in manufacturing structures or units used in the farming/agricultural industry as our triple coated non-porous exteriors prevent bacteria from penetrating the surface of the products.

We would like to start by expressing our gratitude towards our readers for sharing their overwhelming response to our recent blogs. Previously we had covered a topic How Zinc-Tech™ ILG Can Boost Your Production Volume?, today with this blog post we would like to share the versatility of Zinc-Tech™ In-line galvanizing process. Zinc-Tech™ ILG is the most up to date and technologically advanced process which has been continuously refined to perfection. The versatility of this process is so beneficial it should be of interest to anyone who would wish to improve their operations. Let’s move ahead and discuss a few benefits of its versatility.

Previously our blogs had introduced, What is Zinc-Tech™ ILG (In-line galvanizing)? And How it Works, with an intention to help our readers understand the ILG process and how they can benefit from it. Today with this blog post we intend to explain how Zinc-Tech™ ILG can boost your production volume As you are aware, the conventional hot dip galvanizing process involves a method of processing tubulars piece by piece, because of its design the process has certain limitations. Let us understand the hot dip process.

The Zinc-Tech™ ILG (In-line galvanizing) process is the most technologically advanced and is deemed to be revolutionary for the hot dip galvanizing industry. Zinc-Tech™ ILG has various unique features which sets it at the apex of galvanizing technology. Superior Technologies Inc., has been working towards continuously evolving the process with innovation to help the users reach tremendous benefits. Let us have a look at what makes our ILG technology stand out from existing solutions:

Earlier we briefly introduced the In-Line Galvanizing (ILG) process and its design that allows it to be integrated to existing tube manufacturing lines. This time, we want to answer questions about the process technology, specifically what ILG is and its basic fundamentals. Let us begin by introducing the different components that make up our Zinc-Tech™ process.
