What are the 4 types of copper tubing?
Copper pipe manufacturers offer four standards of copper pipe which are types L, M, DWV, and K. These letters partially indicate the relative pipe wall thickness. A pipe's wall thickness is dependent on the pipe size.
Is copper tubing sized by OD or ID?
The nominal size of copper pipe is always smaller than the OD measurement. 1/2- inch pipe is the measurement of copper pipe that is 5/8 inch OD. The ID is affected by wall thickness.
Which copper is thicker L or M?
Type L copperType L copper is thinner than Type K but thicker than type M.
What is the difference between copper tubing and copper piping?
Tubing is usually more expensive than pipe due to tighter manufacturing tolerances. Interestingly, while the stated and measured OD's of tubing are almost exact in most cases, copper tubing generally has a measured OD that is 1/8” larger than stated OD. As such, maybe it should be called copper pipe.
When did they stop using copper pipes in houses?
Copper was the plumbing pipe of choice from the 1950s until 2000 and was widely used both in new construction and to replace the galvanized steel water supply pipes that had been the standard into the 1950s.
How do I know what size copper pipe I have?
How to Size Your Water Supply Lines with Copper PipesFind out the circumference of the pipe by wrapping the string around the pipe once. ... Lay the string out on a flat surface. ... Divide the length by 3.143, and this is the outer diameter of your pipe.More items...•
Do you measure pipe inside or outside?
Tubing is measured by the OUTSIDE DIAMETER (O.D.), specified in inches (e.g., 1.250) or fraction of an inch (eg. 1-1/4″). Pipe is usually measured by NOMINAL PIPE SIZE (NPS).
What size copper pipe is used in homes?
Generally speaking, the main pipeline from the street to your home is either ¾ or 1 inch in diameter. Supply pipes are ¾ inch in diameter and individual components are ½ inch in diameter.
Is PEX better than copper?
PEX pipe is not only cheaper than copper but more durable too. PEX is immune to corrosion and mineral build-up, and it's not affected by electrolysis, which can cause small pinhole leaks in copper piping. Copper pipes can last anywhere from six months to the life of a building.
Should I use type L or Type M copper pipe?
When to use Type L and Type M copper pipe sizes. Type L copper pipe is recommended where you need strength and protection. But for normal “in the wall” household plumbing, Type M copper pipe is just fine.
Are SharkBite fittings reliable?
John Guest quick-connect and SharkBite fittings are both reliable and awesome fittings for emergency fixes. Even though Quick-Connect and SharkBite fittings are rated for use underground and behind walls, soldering pipes may be the smarter choice.
What are the different types of copper tubing?
There are two basic types of copper tubing, soft copper and rigid copper. Copper tubing is joined using flare connection, compression connection, pressed connection, or solder.
What is the difference between Type K and Type L copper tubing?
Type K is the heaviest. Type L is medium weight and used most often for water lines in homes. Type M is thinner and is used underground or for light domestic water lines if local codes allow.
Should I use Type M or Type L copper?
When to use Type L and Type M copper pipe sizes. Type L copper pipe is recommended where you need strength and protection. But for normal “in the wall” household plumbing, Type M copper pipe is just fine.
What are the color codes for copper tubing?

What type of copper pipe is used in commercial construction?
The three most common types of copper pipe used in residential and commercial construction are Type K, Type L, and Type M. A fourth type, used for drain-waste-vent, or DWV, piping, can be found in some older homes.
What is copper pipe used for?
Copper pipes are commonly used in the construction industry for water supply lines and refrigerant lines in HVAC (heating, cooling, and air-conditioning) systems . Copper pipes can be manufactured as soft or rigid copper and offer excellent corrosion-resistance and reliable connections.
What is type M copper pipe?
Type M Copper Pipe: Type M copper pipe is thinner than both type K and L copper pipe. Sold in both rigid and flexible forms, Type M is used most commonly for heating water services and vacuum systems. It can be used with sweat, compression, and flare fittings. Type M tubing is favored for residential work for its relatively low price; a thinner wall means less copper and thus a lower price. Type M copper is not always allowed by plumbing codes in all areas and applications. Always check with the local building authority for restrictions on its use.
What is DWV pipe?
It is suitable only for above-ground applications and has a low-pressure rating, typically lower than the water pressure of most municipal water supply systems. DWV pipe usually has yellow markings to distinguish it from M type copper. Read More.
What type of copper pipe is used for sweat?
It is available in rigid and flexible forms and can be used with sweat, compression, and flare fittings. Type L is considered the most common type of copper piping, as it can be used in many more applications than Type K. Flexible Type L copper can be used to repair or replace old water lines, although rigid tubing is more durable.
What is type K pipe?
Type K pipe is available in a rigid and flexible form and can be used with flared and compression fittings. It is recommended for main water lines and underground installations because its thickness helps it withstand the pressure from backfilled earth in trenches.
Is copper pipe type L or M?
Type L copper is thinner than Type K but thicker than type M. Type M Copper Pipe: Copper pipe type M wall is thinner than both type K and L copper. Sold in both rigid and flexible forms, Type M is used most commonly for heating water services and vacuum systems. It can be used with sweat, compression, and flare fittings.
What is Nominal Pipe Size?
Nominal pipe size (NPS) is the number that defines the size of the pipe. For example, when you say 6” pipe, the 6” is the nominal size of that pipe. However, for the pipe sizes, NPS 14 and above Outside Diameter is the same as NPS. To understand this concept, you have to learn the way pipes are manufactured.

Note-4: For thin-wall pipe, the ovality in any one cross-section shall not exceed 1.5 % of the specified outside diameter.
What is Pipe Schedule?
The pipe schedule is the way pipe wall thickness is mentioned. To simplify the ordering of the pipe ASME committee has developed Schedule Number which is based on modified Barlow’s wall thickness formula.
What is Pipe NB (Nominal Bore)?
NPS is frequently referred as an NB (Nominal Bore). As such, there is no difference between N B and NPS. NB is also an American way to refer pipe dimensions. I have also seen that when pipe dimensions are shown in mm (DN) people refer pipe sizes in NB. So when someone says 25nb pipe or 50nb pipe basically they are talking about DN.
What is NPS in pipe?
Nominal pipe size (NPS) is the number that defines the size of the pipe. For example, when you say 6” pipe, the 6” is the nominal size of that pipe. However, for the pipe sizes, NPS 14 and above Outside Diameter is the same as NPS. To understand this concept, you have to learn the way pipes are manufactured. Manufacturing of NPS ⅛ (DN 6) ...
Is NPS 2 pipe ID the same as NPS 14?
From the above table, you can see that for NPS 2, Pipe ID is near to pipe NPS and for NPS 14 pipe OD is same as NPS.
Is schedule 80 pipe thicker than schedule 40?
Schedule 80 pipe is thicker than schedule 40 pipe. Look at the above formula of schedule number, allowable stress for material at a given temperature is fixed. That means with an increase in service pressure schedule number will increase which is a pipe wall thickness designator.

How long is steel pipe?
The standard length for buying steel pipe is 21 feet. Anyone who works with steel pipe will be aware that it is generally sold in lengths of 21 feet. Although several theories exist as to why this is, the actual reason is most likely due to its manufacturing history. Advertisement.
