What is the difference between Type K and Type L copper tube?

Type K and Type L are wall thickness types of copper water tube under ASTM B88 and its metric version B88M, listed in the SASO annex. Type K has the heavier wall and is often chosen for buried or higher pressure service in Saudi Arabia, while Type L is common for building plumbing.

Why are copper refrigerant and medical gas lines brazed under nitrogen?

Brazing copper refrigerant and medical gas lines with a nitrogen purge stops oxide scale forming inside the tube. In Saudi installations that scale can damage air conditioning compressors or contaminate hospital gas, so the brazing procedure should state the purge and filler alloy.

Who supplies copper tube in Saudi Arabia?

Much of the copper tube sold in Saudi Arabia comes from mills such as Mueller, KME, Wieland, Golden Dragon, Mehta, Mettube and Halcor and sold through distributors in Riyadh, Jeddah and Dammam. Fittings come from makers such as NIBCO, Conex Bänninger and Yorkshire.

Copper pipes and fittings in Saudi Arabia are seamless copper tubes with soldered, brazed, press or compression fittings, used in premium plumbing, air conditioning refrigerant lines and hospital medical gas, and they are covered by SASO's pipes regulation, which lists copper pipes (HS 7411) and copper fittings (HS 7412). This page belongs to the Saudi pipes and fittings category and focuses on copper alone: tube standards, fitting choice, the SASO certificate, Saudi climate effects and supplier checks. Points were checked in October 2026.

What copper tubes are used in Saudi Arabia, and for what?

Saudi buyers order copper in three families: water tube for plumbing, ACR tube for refrigerant lines and specially cleaned tube for medical gas. Specify the family and its standard, because the cleanliness and capping rules differ.

Family	Saudi applications	Standard and what to state
Copper water tube, metric	Hot and cold water in villas, hotels, hospitals, mosques and offices	SASO-GSO-ASTM-B88M (metric, Types K and L), named in the SASO annex; or GSO EN 1057 on European designs
ACR tube	Split, package and VRF air conditioning, cold stores and supermarkets	ASTM B280 or EN 12735-1; coils or straight lengths, cleaned and capped
Medical gas tube	Oxygen, medical air and vacuum in hospitals and clinics	ASTM B819 or EN 13348; installed to the medical gas code in the design
Capillary and press fittings	All of the above	GSO EN 1254-1 (6 to 108 mm) on EN systems; ASME B16.22 on US systems

Many Saudi residential projects now use PP-R hot and cold water pipe instead of copper, and HDPE pipe for buried services, so copper is chosen where the design asks for metal or for refrigerant and gas duties. Copper mill products are under industrial copper pipes and tubes, refrigerant systems under HVAC and district cooling and industrial refrigeration, and hospital pipelines under medical gas systems.

What does SASO require for copper pipes and fittings?

Copper tube and fittings for water and gas in Saudi buildings need a SASO certificate of conformity under the Type 3 model, or the Saudi Quality Mark or equivalent, before they are sold, as of 2026.

Requirement	For the copper buyer	Authority
Certificate of conformity or Saudi Quality Mark	Must name the mill, tube standard and size range	SASO, through SABER
Customs items 7411 (copper pipes) and 7412 (copper fittings)	Imported tube and fittings are checked at clearance	SASO and customs
SASO-GSO-ASTM-B88M	Metric copper water tube, Types K and L	SASO
Metric nominal diameters; no soft conversion from inch sizes	Imperial ACR sizes need checking against SABER before import	SASO
Saudi Building Code	Design and installation still follow the SBC	Saudi Building Code National Committee

SASO says its annex is under review and the products and codes on SABER are current, so confirm how your HS code is treated there; refrigerant tube sold in inch sizes is the case most worth checking early. Our SASO and SABER certificate guide explains product and shipment certificates. Fire sprinkler pipework is excluded from the regulation.

How do Saudi conditions affect copper pipework?

Heat is not the issue for copper; condensation, external corrosion and jointing quality are.

Sweating lines. Refrigerant suction and chilled water branches condense in Jeddah and Dammam humidity. Insulate with closed-cell pipe insulation and seal every joint.
Salty ground. Copper buried in sabkha or salty fill along the Gulf and Red Sea coasts can corrode externally; use coated tube or sleeving.
Brazing. Refrigerant and medical gas joints are brazed under a nitrogen purge to avoid oxide scale that damages compressors and contaminates gas.
Dust on site. Keep ACR and medical gas tube capped until jointing; sand inside the bore is hard to remove.

Who supplies copper pipes and fittings in Saudi Arabia?

Most copper tube sold in the Kingdom comes from mills in Europe, the US and Asia through distributors in Riyadh, Jeddah and Dammam; for imports, the importer holds the SASO certificate.

Water and medical gas tube. Mueller copper water and medical gas tube, KME copper tube, Wieland copper tube and Maksal tube.
ACR tube. Golden Dragon ACR and inner-grooved tube, Mehta ACR coils, Mettube ACR tube and Halcor copper tube.
Fittings. NIBCO copper fittings and press systems, Conex Bänninger fittings and Yorkshire capillary fittings.

Ask for the SABER certificate, mill test certificates with standard, size and temper, cleanliness statements for ACR and medical gas tube, and matching fitting certificates. For project quantities buy through the mill's appointed distributor. See our supplier sourcing guide, or post a copper pipe requirement with tube type, sizes and city.

What affects copper pipe prices and delivery in Saudi Arabia?

Copper price. Offers usually follow the LME price, with short validity.
Tube family. Medical gas and ACR tube cost more than plain water tube because of cleaning and capping.
Wall type and temper. Type K weighs more than Type L.
Certification. SABER-registered products clear faster at King Abdulaziz Port or Jeddah Islamic Port.
Fittings choice. Press fittings cost more but save labour and hot work permits.

Frequently Asked Questions — Copper Pipes & Fittings

Do copper pipes need a SASO certificate in Saudi Arabia?

Yes. Copper pipes and fittings for water and gas in Saudi buildings fall under SASO’s Technical Regulation for Building Materials Part 5, which lists copper pipes under HS 7411 and fittings under HS 7412. The supplier needs a certificate of conformity or the Saudi Quality Mark.

Which copper tube standard does SASO list?

The SASO pipes regulation annex lists SASO-GSO-ASTM-B88M, seamless copper water tube in metric sizes for Types K and L. SASO says the SABER listing is the current version, so confirm the standard and HS code there before importing copper tube into Saudi Arabia.

What copper tube is used for air conditioning in Saudi Arabia?

Air conditioning refrigerant lines in Saudi Arabia use ACR copper tube to ASTM B280 or EN 12735-1, cleaned, dehydrated and capped at both ends. Because SASO requires metric sizes, check how inch-sized ACR tube is treated on SABER before ordering imports.
