Copper Pipe for Gas Fitting

Quick Answer: The Copper Pipe for Gas Fitting is copper tube used to carry fuel gas, such as LPG or piped natural gas, from the cylinder manifold or meter to the gas taps on laboratory benches, where Bunsen burners are then connected with flexible tubing.

Why Copper Is Used for Lab Gas Lines

Copper tube has a long history in gas installations because it resists corrosion from the gas and from most indoor environments, can be bent to follow benches and walls, and can be joined reliably by brazing or with compression fittings. Soft-temper copper is supplied in coils and bent by hand or with a bender; hard-drawn copper comes in straight lengths for neat, clipped runs along walls.

In a school or college chemistry lab, copper pipe for gas fitting typically runs from a gas manifold or meter, through an isolating valve at the lab entrance, along the benches, and ends at the individual gas taps. Only the last short link, from tap to burner, is flexible tubing such as the Safety Burner Tube.

The diameter, wall thickness and temper required depend on the gas, its pressure and the length of the run, and local gas-safety codes set the rules. Installation and pressure testing should be carried out by a qualified gas fitter; this page describes the product and its purpose, not an installation method.

Specifications

Applications

• Gas lines from an LPG cylinder manifold to bench gas taps in school chemistry labs.
• Extending an existing lab gas line to new benches during refurbishment.
• Utility gas lines in college and research labs, where copper is compatible with the gas used.
• Replacing corroded or damaged sections of older gas pipework.

Safety and Handling

• Use a qualified gas fitter for installation, alteration and pressure testing.
• Test joints for leaks with a leak-detection solution or a gas detector, never with a flame.
• Clip pipes securely and protect them where they pass through walls or run near bench edges.
• Keep the main isolating valve accessible and labelled so that the lab supply can be shut off quickly.

Why Choose LabEquip

Laboratory builders and schools upgrading their gas services buy copper pipe together with the fittings for their benches. LabEquip lists it under General Lab Products; a Combustible Gas Detector is a sensible companion for leak checks, and diameters and lengths can be agreed through the contact page.

Frequently Asked Questions

Is copper pipe suitable for LPG lines in a lab?

Copper tube is widely used for LPG and natural gas installations, but the permitted diameter, wall thickness and joining method are set by local gas codes. A qualified gas fitter should settle the specification for your installation.

What is the difference between soft and hard copper pipe?

Soft-temper copper is annealed, comes in coils and can be bent by hand for short runs. Hard-drawn copper is stiffer, comes in straight lengths and is bent with a bender or joined with fittings at corners.

How are copper gas pipes joined?

Usually by brazing or with compression or press fittings approved for gas. Which methods are allowed differs between local codes, so the fitter follows the rules that apply where the lab is built.

How do you check a gas pipe for leaks?

After installation the line is pressure tested by the fitter. For routine checks, brush a leak-detection solution over the joints and watch for bubbles, or use a gas detector. Never use a flame to look for leaks.

Can copper pipe carry other lab gases?

Copper suits several laboratory gases, but some react with it; acetylene, for example, can form explosive copper compounds. Check compatibility for any gas other than the fuel gas the line was designed for.

Who should install a lab gas line?

A qualified gas fitter, following local gas-safety regulations. Teachers and lab staff should only operate the bench taps and the isolating valve, and report any smell of gas at once.
