The Ins and Outs of 2 Inch Galvanized Pipe: A Handy Guide for Any Project
Whether you’re building a fence, framing a new shed, or putting the finishing touches on your farm equipment, having the right sizes and types of metal pipe on hand is essential. For many outdoor applications and structural supports, 2 inch galvanized steel pipe hits the sweet spot – sturdy enough to handle heavy loads, but easier to work with than larger diameters. In this handy guide, we’ll walk through everything you need to know about working with 2 inch galvanized steel pipe.
What is Galvanized Pipe and Where Can It Be Used?
Galvanized pipe refers to steel pipe that has been coated with zinc to protect it from rust and corrosion. This makes galvanized pipe well-suited to outdoor projects or any setting where pipes may be exposed to moisture and other weather elements over time. The zinc coating forms a protective barrier, allowing the pipe to stand up to years of use without degrading. While more expensive upfront than non-galvanized steel pipe, galvanized pipe saves money in the long run by avoiding the need for frequent replacements of rusted pipe.
In addition to its weather-resistance, galvanized pipe offers excellent durability, high strength-to-weight ratio, ease of installation, and availability in standardized sizing. You’ll see galvanized pipe used for things like fence posts, cattle guards, trailer frames, flag poles, scaffolding systems, and more. It can also be used for water delivery in agricultural settings, greenhouses, outdoor wash stations, and other non-potable water transfer applications.
Understanding 2 Inch Galvanized Pipe Dimensions and Specifications
While galvanized steel pipe comes in sizes ranging from 1⁄2 inch to over 6 inches in diameter, 2 inch galvanized pipe represents one of the most widely used sizes for do-it-yourself and commercial projects. Under standards from the American Society for Testing and Materials (ASTM), 2 inch galvanized steel pipe features the following specifications:
Outer Diameter: 2.375 inches
Inner Diameter: 2.067 inches
Wall Thickness: 0.154 inches
These standardized dimensions allow for interchanging 2 inch galvanized pipe supplied by different vendors, predictable fit with pipe fittings, and reliable threading. The 0.154 inch wall thickness provides ample strength for structural supports, pressure systems, and heavy implement frames while still keeping the weight manageable for one or two people to work with. Always source 2 inch galvanized steel pipe from reputable dealers that adhere to ASTM specifications.
5 Key Benefits of Using 2 Inch Galvanized Pipe
Now that we’ve reviewed basic specs, let’s drill down into five of the best assets offered by 2 inch galvanized steel pipe:
1.Corrosion Resistance – With pipe walls fully coated in a protective zinc layer, you’ll avoid obnoxious rust problems over years of service. This means galvanized pipe can be directly buried or set in concrete without special treatments to prevent corrosion.
2.Structural Integrity – The standard 0.154 inch wall thickness strikes a winning balance of strength, weight, and cost. It’s overbuilt for water and many structural supports.
3.Standard Sizing – With outer diameter fixed per ASTM standards, 2 inch galvanized pipe works seamlessly with common fittings like elbows, tees, reducers and couplers. No surprises!
4.Cost Effectiveness – You’ll pay a few dollars more per foot than plain steel, but save hugely over time with corrosion protection. 2 inch diameter hits a good economy of scale.
5.Availability – As a core building product, every hardware store stocks 2 inch galvanized pipe along with associated fittings. You can also order pre-cut lengths from any steel supplier.
Techniques for Cutting, Threading, and Working With 2 Inch Galvanized Pipe
While working with 2 inch galvanized pipe is typically faster and easier than larger diameters, having the right metalworking tools on hand is a must. Here are some of our best tips:
•Use a tubing cutter or portable bandsaw with metal-cutting blade for straight cuts free of kinks or deformation. A hacksaw also works for short pieces.
•Deburr cut ends with a knife, file, or deburring tool so threads cut clean and don’t leave metal shards that risk corrosion inside the freshly exposed steel.
•Thread pipe with a quality 2 inch pipe threader compatible with Galvanized Iron Pipe Size (GIPS) standards. Ensure proper thread profile and depth for leak-free connections.
•When running long sections of pipe, use joining sleeves, couplings, unions or flanges to connect instead of threading the entire length.
•Protect coated exterior surface from scratches during handling. Touch up any damage with a cold galvanizing zinc compound.
•Use pipe size-specific fittings, brackets, hangers, etc. for secure 2 inch galvanized pipe installations.
The combination of corrosion resistance, strength, standardized sizing, and wide availability makes 2 inch galvanized steel pipe a go-to solution for countless outdoor infrastructure projects. Following proper cutting, threading, joining and handling techniques will keep your system functioning smoothly for decades to come. Reach out with any questions!
