Seamless vs Welded Pipe

Selecting between seamless and welded pipe depends on pressure rating, corrosion environment, and budget. The matrix below helps buyer to take right decision for each service condition.

Seamless Pipe

No weld seam, it made from a pierced solid billet
Uniform wall thickness throughout
Higher pressure ratings than welded pipe
Required for sour service (H2S) per NACE MR0175
Covers ASTM A106, API 5L, A335, A213, A519, A269
Higher cost, but longer service life
Available from 1/8" to 26" NPS

Welded Pipe

Rolled from flat plate and welded longitudinally
Weld seam requires extra NDE inspection
Suited for low-pressure and water service
Not recommended for sour service or cyclic duty
Covers API 5L, ASTM A53, A671, and A672
Lower cost for large-diameter pipelines
Available in larger diameters beyond SMLS limits

Seamless Steel Pipe Price Factors in Saudi Arabia

Seamless steel pipe price varies significantly by grade, schedule, mill origin, and market conditions. Understanding the factors below helps buyer negotiate effectively and time purchases to minimise total landed cost at Saudi Arabia ports.

Raw Material (HRC / Billet)

Impact: Very High

45–55%of ex-mill price driven by global billet and HRC costs

Buy at billet low-typically Q1-to lock in better pipe pricing

Monitor LME & MEPS Weekly

Schedule / Wall Thickness

Impact: High

SCH 160commands 40–70% premium over SCH 40 in same size and grade

Specify only the schedule required by design calculations

Match Schedule to Pressure Rating

Frequently Asked Questions

ASTM A106 covers hot-finished seamless carbon steel pipe for high-temperature service up to 482°C. ASTM A53 covers both seamless and welded pipe for general-purpose applications

PSL stands for Product Specification Level. API 5L PSL1 sets the basic requirements for line pipe . PSL2 adds mandatory Charpy impact toughness testing, tighter chemistry limits

Yes. Seamless hydraulic tubing governed by ASTM A269 or EN 10305-4 is specifically designed for hydraulic and pneumatic systems. Standard seamless steel tubing per ASTM A213 or A519 is acceptable for pressure service

Seamless casing pipe is the steel liner run inside a drilled oil or gas well to prevent formation collapse. In Saudi Arabia’s Arab Formation wells, N80 and P110 are the most common production casing grades.
