Type L Seamless Copper Tube – C12200

Description

Type L Seamless Copper Tube – C12200

🧩 Product Overview

The Type L Seamless Copper Pipe is a medium-wall copper water-tube category selected by dimensions, temper and intended service. Manufactured from high-purity C12200 phosphorus-deoxidized copper, ASTM B88 is the seamless copper water-tube reference. Confirm the ordered dimensions, condition and inspection requirements.

Thanks to its balance between durability, strength, and workability, the Type L Seamless Copper Pipe is selected by engineers, contractors and system designers against the applicable water, fire-protection or cooling-system requirements. Confirm pressure, temperature, joining method and the ordered specification for the actual installation.

🔩 What is Type L Seamless Copper Pipe?

The Type L Seamless Copper Pipe refers to a copper water tubing category defined by the ASTM B88 standard. It features a medium wall thickness that provides an ideal balance between strength and flexibility. “Seamless” means the pipe has no welded seams or joints, while joints, service conditions and installation quality remain part of the engineering acceptance requirements.

For plumbing or HVAC enquiries, identify the service fluid, pressure, temperature, temper and required specification. Refrigeration or ACR use requires its own applicable tube and cleanliness requirements; Type L naming alone is not that qualification.

In ASTM B88, three types of copper pipes are defined:

• Type K: Thickest wall, used for high-pressure and underground applications

• Type L: Medium wall; confirm plumbing or HVAC suitability against the actual temper and ordered specification

• Type M: Thinnest wall, typically used for low-pressure interior systems

The Type L Seamless Copper Pipe offers the best compromise between cost, mechanical strength, and installation ease.

🧪 Material Composition: C12200 Copper Alloy

Our Type L Seamless Copper Pipes are manufactured using C12200 copper alloy – a phosphorus-deoxidized copper known for its excellent corrosion resistance, formability, and thermal conductivity.

🔬 Typical Chemical Composition of C12200:

Phosphorus is used to deoxidize the copper during production, which enhances the alloy’s welding and brazing properties while maintaining high conductivity and resistance to internal corrosion.

The catalogue lists nominal sizes, outside diameters and wall thicknesses below. Confirm the ordered ASTM B88 dimensions, temper and inspection requirements for the actual tube.

📌 Temper Available: Soft (annealed) or hard-drawn
📌 Length: 3–6 meters standard, custom cutting available
📌 Ends: Plain / beveled / threaded on request

🔧 Installation Guidelines

One of the key advantages of Type L Seamless Copper Pipe is its ease of installation. It supports various joining methods:

• Soldered joints using lead-free solder

• Brazed connections for high-pressure HVAC systems

• Compression fittings for repair and modular systems

• Push-to-connect fittings for fast field installations

🔒 Installation Tips:

• Clean and deburr pipe ends before joining

• Use only lead-free flux and solder for potable systems

• Avoid over-heating to protect the inner surface

• When burying pipes, use sand bedding for additional protection
