What are Assorted/Block Pipes?

Assorted pipes generally refer to surplus, secondary, or slightly defective steel pipes sold in bulk lots for diverse applications. These are for non-critical uses. Temporary structures, fencing, or water management are typical applications. Precision oil and gas drilling would not use this material. The pipes are often leftover from large projects or overstocked materials. This makes them an affordable choice for structural or general piping needs. In these cases, exact specifications are not the most vital thing.

Types of Secondary Seamless Assorted & Block Pipes

We offer three main categories of secondary assorted and block pipes:

  • Assorted: Mixed sizes in a single grade with various dimensions within one material specification.
  • Block Lot: A full shipment purchase where you buy the whole container or inventory lot at a bulk price.
  • Mixed Grade: Buy a single item with different grades, sizes, and types of materials.

Advantages

Some of the main benefits of buying secondary assorted and block lot pipe are:

  • Significant Cost Savings: 30% to 50% less than the price of prime materials, depending on the condition of the lot.
  • Immediate Availability: Ready stock means no lead time for standard mill orders.
  • Suitable for Many Applications: Functional material for both structural and non-critical uses.

Secondary Seamless Assorted & Block Pipes Specifications

To identify suitable materials for non-critical applications, refer to the secondary and surplus pipe specifications detailed below:

Dimensions ASTM, ASME and API
Size (Seamless) 30 mm to 800 mm with thickness of 5 mm and above
End Plain End, Beveled End, Screwed, Threaded
Length Single Random, Double Random, Required Length, Custom Size

Applications of Secondary Seamless Assorted & Block Pipes

Secondary assorted and block pipes serve various industries for non-critical applications where cost savings matter.

Plumbing

General plumbing work, drainage systems, and utility piping use this material when the budget is the primary consideration. Contractors choose secondary grade for projects where premium pipe is not justified.

Chemical Industry

Non-critical process support, utility lines, and general plant piping use secondary pipes. Code requirements do not apply to these systems. Plants save money on auxiliary infrastructure this way.

Water Supply Systems

Irrigation, industrial water distribution, and non-potable water systems accept secondary grade material. These applications do not require the precision of potable water piping. Cost reduction drives the material choice here.

Oil and Gas Pipeline

Temporary installations, non-critical utility lines, and support infrastructure use secondary pipes. This material is not under pressure code requirements. Field operations rely on it for temporary setups and auxiliary systems.

Fabrication Industry

Structural fabrication, general manufacturing, fencing, and temporary structures use secondary pipes. Material certification is not required in these applications. Fabricators get functional pipes at a lower cost.

Power Plant

Auxiliary systems, non-pressure service, and maintenance applications in power generation facilities use this material. Critical steam lines would never use secondary grade. But support infrastructure and maintenance work can benefit from the cost savings.

Paper & Pulp Industry

General mill piping, support structures, and utility service use secondary grade material. These systems operate at lower pressures and temperatures. Mills choose this material where it makes economic sense without compromising safety.
