AZEIDK supplies its black and hot-dip-galvanized steel pipes for fire sprinkler and firefighting networks in Schedule 10 and Schedule 40 up to 6 inches; the pipes appear in UL’s certification database, and the manufacturer’s documentation cites FM approval.
Key takeaways
- KD Industries was established in 2000 and makes welded steel pipe from 1/2 inch to 6 inches, according to its website.
- AZEIDK supplies KDI fire protection pipe in Schedule 10 to ASTM A795 and Schedule 40 to ASTM A53, black or hot-dip galvanized.
- UL Product iQ lists the company under Metallic Sprinkler Pipe, file EX27954, for models 10 and 40; the manufacturer’s documentation cites FM Approvals Class 1630.
- Schedule, joining method and working pressure come from the approved design and hydraulic calculations, not the brand name.
- In Saudi Arabia, the Saudi Fire Protection Code (SBC 801) and Civil Defense set the applicable standard editions.
Who is KD Industries?
On its official website, the company describes itself as an ERW pipe manufacturer and supplier in Dubai, established in 2000. It produces pipe from 1/2 inch to 6 inches with wall thicknesses of 1.2 to 7 mm, plus square and rectangular hollow sections, and lists fire sprinkler systems among its applications alongside structural and water supply uses.
In UL Product iQ, file EX27954 is held by K.D Industries Inc under the Metallic Sprinkler Pipe category (VIZY), with models 10 and 40. UL 852 covers metallic pipe for water-based fire protection systems and classifies it by size, pressure rating, end configuration and wall thickness; steel pipe is also classified by its corrosion resistance ratio (CRR).
KDI pipes supplied by AZEIDK
Our KDI fire sprinkler pipe product page describes carbon-steel welded pipe for automatic sprinkler and firefighting networks, black or hot-dip galvanized, with UL and FM documentation. Key published data:
- Schedule 10: lightweight pipe to ASTM A795 Grade A or B; the UL certificate shows 3/4 inch through 6 inches.
- Schedule 40: black or galvanized pipe to ASTM A53 Grade A or B; the UL certificate shows 1/2 inch through 6 inches.
- Joining: grooved couplings, welding with beveled ends, or threaded and coupled ends on selected sizes.
- Pressure: the FM documentation covers rated working pressure up to 300 psi, depending on size and approved installation configuration.
- Production checks: hydrostatic testing, ultrasonic weld seam inspection, and dimensional and weight checks.
The page also states that factory hot-dip-galvanized pipe can be used in dry-pipe systems within the applicable FM approval scope, and that schedule, grade, joining method and pressure must follow the approved drawings, hydraulic calculations and project specification.
Where these pipes are used
The product page lists automatic sprinkler systems, fire hydrant and hose networks, fire pump rooms, fire water supply lines, and wet and dry pipe systems, with galvanized pipe selected for dry systems. The table summarizes what the manufacturer and AZEIDK publish:
| Product line | Typical use | Specification or listing as published |
|---|---|---|
| Schedule 10 (ASTM A795) | Branch lines and mains with grooved or welded joints | UL 852 listing for 3/4 to 6 inches per the certificate; FM approval for 1 to 6 inches, varying with pressure and joining method, per the manufacturer’s documentation |
| Schedule 40 (ASTM A53) | Threaded small-bore lines, mains, hydrant networks and pump rooms | UL listing for 1/2 to 6 inches per the certificate; FM documentation for the same sizes, up to 300 psi depending on size and configuration |
| Hot-dip-galvanized pipe | Dry systems where the design calls for it | Within the applicable FM approval scope, per the manufacturer’s documentation |
What to check before approving supply
- Search UL Product iQ for file EX27954, confirm the model (10 or 40) and size are covered, and check that the UL mark is printed on the delivered pipe.
- Ask for the FM approval and confirm it in the FM Approval Guide; the manufacturer’s documentation cites approval PR455384, and the approved pressure varies by size and joining method.
- Match the joining method to the wall: the ASTM A795 scope lists rolled grooving, welding and plain-end fittings for lightweight pipe, and threading only for standard-weight pipe.
- Compare the highest expected system pressure with the pipe rating for the chosen size and joining method.
- When comparing thin-wall pipes, ask for the CRR value from the listing information.
- Request mill test certificates for the ASTM grade and hydrostatic test results for each batch.
- Check SABER conformity where the product falls under a technical regulation of the Saudi Standards, Metrology and Quality Organization (SASO), as our SABER conformity news explains.
- Obtain consultant approval and Civil Defense acceptance of drawings and calculations before supply.

FAQ
Are KDI pipes UL listed and FM approved?
UL Product iQ shows file EX27954, held by K.D Industries Inc, under Metallic Sprinkler Pipe for models 10 and 40. FM approval is stated in the manufacturer’s documentation under Class 1630, approval PR455384, and should be confirmed in the FM Approval Guide. In every case, check that the mark is on the delivered pipe and the size is covered.
When should I choose Schedule 10 or Schedule 40?
The approved design, joining method and working pressure decide. Schedule 10 is lighter and is usually joined by grooved couplings or welding, while Schedule 40 also suits threading. The sizes and pressures covered differ between the UL and FM documents, so review them against the hydraulic calculations.
Can Schedule 10 pipe be threaded?
AZEIDK describes KDI Schedule 10 as lightweight pipe to ASTM A795, and that standard’s scope lists rolled grooving, welding and plain-end fittings for lightweight pipe, with threading listed for standard-weight pipe. Use threaded joints only for the sizes and walls that the manufacturer’s documentation and the design allow.
Do dry systems need galvanized pipe?
The adopted standard and the design decide. The product page states that factory hot-dip-galvanized pipe can be used in dry-pipe systems within the applicable FM approval scope. It is good practice for the consultant to specify the pipe type, taking water quality, operating conditions and authority requirements into account.
What sizes does AZEIDK supply?
The AZEIDK product page shows pipe up to 6 inches. The UL certificate covers Schedule 10 from 3/4 inch to 6 inches and Schedule 40 from 1/2 inch to 6 inches, while FM sizes vary with pressure and joining method. Contact our team to confirm the sizes and quantities for your project.
