Standard Specification for Welded and Seamless Steel Pipe Piles

This specification covers nominal (average) wall steel pipe piles of cylindrical shape and applies to pipe piles in which the steel cylinder acts as a permanent load-carrying member, or as a shell to form cast-in-place concrete piles.

ASTM/ASME A252/SA252 Piling Pipe

Our standard and line pipe manufacturing processes ensure the highest quality in end products.

Reliant Pipes ASTM/ASME A252/SA252 steel piling pipe is a structural pipe ideally suited for application in buildings, retaining walls, and other structures needing solid, dependably, quality made steel piling pipe as its structure.

A252 Comparitive Specifications

ASTM Specification A252 describes nominal (average) wall steel pipe piles of cylindrical shape and applies to pipe piles in which the steel cylinder acts as a permanent load-carrying member or as a shell to form case-in-place concrete piles.

Surface imperfections exceeding 25% of the nominal wall in depth are considered defects. Defects not exceeding 22.5% of the nominal wall in depth may be repaired by welding. Before welding, the defect shall be completely removed.

Structural Steel Pipe

ASTM A 252 Grade 2 / ASTM A 252 Grade 3 & Limited Service Pipe

ERW Carbon Steel Pipe Fabrication / Pipe Pilings & Steel Casings

Structural Grade Steel Pipe

A leading structural steel pipe supplier, Reliant Pipes Supply Company stocks large quantities of ASTM A252 Grade 2 & Grade 3 Carbon Steel Pipe. On-hand inventory includes 2" - 48" OD in various thicknesses. Limited service pipe is readily available on our yard.

We custom fabricate and sell pipe to customers serving construction segments such as building construction, road construction, bridge construction, utility construction, marine construction, and oilfield construction just to name a few. Our Welded Steel Pipefinished products are installed by those performing horizontal road boring, directional drilling, and pile driving procedures for these industries. We have two specialty niches. The first includes fabricating 20' dead length stock sections for use as Steel Casings, such as Road Bore casing, Culvert casing, Open Cut casing, Open Tunnel casing, and Water Well casing. The picture above shows some of these 20' sections on our yard. The second includes custom fabricating Steel Pipe Pilings, such as Foundation piling, Bridge piling, and Marine piling, including pier pilings, dock pilings, and deep water pipe pilings to length.

Fabricated to Length

We bevel cut, weld and coat casings and pilings to your specifications. Our standard cutting is to mechanical torch bevel cut to 30°, then perform full penetration circumferential welds. We offer options for mid-welds or no welds depending upon the length required. We have production capacity to process pipe up to + - 93 ft. in length. Options include welding and fabricating steel plate, shoes, and conical points. Lining and Coating options include bituminous coating, coal tar epoxy coating, and cement lining for the different types of applications.

Other structural pipe applications include: sign posts, roadway billboard signs, caissons, and tower construction such as in water towers. A third specialty niche, we manufacture pipe bollards. Usually 6 - 12" in diameter, cut to lengths so that about 3 - 4 feet or so will protrude above the ground, encased in concrete, and painted reflective yellow or some noticeable color as compared to the surrounding background scenery, bollards are normally used to protect a zone and to form a barrier from vehicle traffic. A bollard is a rigid post, usually arranged in a line or a closed-loop path to close parking lot traffic from entering the protected space, such as in surrounding gas pump islands, shielding storefront entranceways, and enclosing complete parking lots.

Steel Casing Pipe

Reliant Pipes specializes in ASTM A252 Steel Pipe Casings for the various utility construction industries, including:

• Road Bore Casing
• Culvert and Tunnel Casing
• Open Cut Casing
• Pipe-in-Pipe Casing
• Water Well Casing
• Oil and Gas Transmission Pipeline Casing
• Drilling Casing
• Bare Steel Pipe Casing, Uncoated with coating options

We have a large inventory of ASTM A252 Steel Pipe Casing, Grade 2, Grade 3, and "limited service pipe". Normal inventory includes pipe diameter sizes: 2", 3", 4", 6", 8", 10", 12", 14", 16", 18", 20", 22", 24", 30", and 36". Also available in larger diameters to 110" with wall thicknesses ranging in thickness from .25" - 1" depending upon the pipe OD.

Our limited service pipe is "New and Unused steel pipe" as we have major pipe distributor status with many of the mills. We mill crop or mechanically torch cut and bevel ends to 30º bevel by bevel and bevel x square, weld adjoining pipes together, and produce large quantities of 20 foot dead length sections for stock. From these sections we custom fabricate pipe casings to your specifications. We produce and sell large quantities of custom steel casings for every use.

If you should have the need for open cut casing, we are able to fabricate and ship the exact footage you require per crossing. This reduces time and scrap loss for the contractor. Open cut casing is available in ASTM A252, Grade 2 or 3 along with limited service. Standard end treatment is 30º bevel.

Optional coating services are available from us for underground piping, including Bituminous Asphalt coating and coal tar epoxy coating.

With a sales staff that has been together over 10 years and with most of our machinists each having over 10 years at our plant, our knowledgeable and friendly team is experienced in manufacturing and shipping orders on time, no surprises. We look forward to the opportunity to help you fulfill your steel casing needs.

Cutting Steel Pipe - Cut to length, Welded & Coated Pipe

Reliant Pipes custom cuts and fabricates Structural Grade Carbon Steel Pipe, mid-welding pieces together for our customers. Our specialty is to have in-stock 20' lengths of various diameters and thicknesses ASTM A252 GR2, GR3, and limited use structural pipe. Since 1997, we've earned industry respect across the Southeast & nationwide for on-time delivery of cut-to-length Pipe PilingsSteel Casings and Pipe Bollards. We stock carbon steel pipe in sizes and dimensions ranging from 2" - 48".

With "Bevel x Bevel" or "Bevel x Square" beveled pipe cutting options, we fabricate welded pipe to length specifications. Custom fabricating capacity includes options for welding plate, points, shoes, and flanges into place. Upon customer request, our pipe products are treated with a pipe coating or a pipe lining procedure. When the pipe is delivered on-site to you, it's fabricated to length and coated to your requirements.

Pipe Cutting and Splicing is what we do.

Our Plant is in Mumbai & Gujarat in India

Reliant Pipes offers several types of steel pipe coating processes. The pipe for sale from our yard is sold as is, bare pipe, meaning, there's no coating, inside or outside. There are multiple options for coated pipe for every order. When you request a particular coated pipe, coated inside and/or coated outside, you have a choice of applications for pipe as large as 72"OD.

º Shot Blast & Sand Blast Cleaning available
º Bituminous Asphalt steel pipe coating available (Fast and least expensive)
º Coal Tar Epoxy Coating (Typically applied in two coats, 16 mil minimum)
º Multi-Coat Exterior and Interior Paint systems, Polyurethane, and Tape Wrapping also available

Bare steel pipe will eventually corrode, or rust. Since the total performance of a pipe coating system involves the three separate processes, application to the pipe, handling and storage of the pipe, and in-ground or above-ground service of the pipe; the functional requirements and the resistance to deterioration should be considered when establishing your criteria for the coating properties that we offer.

Bituminous Asphalt Coating

The principal uses for asphalt coatings include internal and external application to carbon steel pipe. Our bituminous asphalt coating has been tested to meet ANSI-A21.4 and AWWA C104 specifications for potable water, and has been found to be acceptable and is certified to NSF Standard 61. This coating is black in color. When applied correctly, this fast coating process provides the cathodic protection required for most underground structural steel pipe. This is the least expensive method we offer for pipe coating for cathodic protection, and we are able to provide reliable response times because this is the least complicated coating process that we offer. Primarily used for road bore casings and other casing pipes.

Epoxy Coating - Sprayed Application

Typical applications include heavy-duty service conditions such as chemical plants, bridge piling structures, and pipelines. Excellent resistance to immersion in salt-water, above ground extreme temperature swings and abrasive wear and tear.
