FITTING

🔧 General Overview – Butt-Welding Fittings

✅ Definition

Butt-welding fittings are pipe components (elbows, tees, reducers, caps) welded directly to piping systems to change direction, branch flow, or reduce pipe size. They’re essential in high-pressure, high-integrity systems like fire protection, HVAC, petrochemical, and industrial networks.

📍 Application Areas

• Fire fighting systems (sprinkler, hydrant, riser lines)

• HVAC systems (chilled water, heating loops)

• Petrochemical and gas plants

• Shipbuilding and offshore platforms

• Industrial piping networks

🧩 Common Fitting Types

• Elbows (90°, 45°) – change pipe direction

• Tees – create branch connections

• Reducers (concentric/eccentric) – transition between pipe sizes

• Caps – seal pipe ends

• Special fittings – custom shapes for specific layouts (e.g. scraper bar tees)

📊 General Technical Specifications

🏷️ Leading Brands in Egypt & MENA

• TTU (Thailand) – widely used in fire fighting and HVAC

• SHIELD (Europe/Asia) – UL/FM certified, premium quality

• Both-Well (Taiwan) – high dimensional accuracy

• BIS Pipe Fitting (Thailand) – cost-effective, reliable

• Benkan (Japan) – top-tier for petrochemical and gas

• Erne Fittings (Austria) – EN/DIN standard fittings

• M.E.G.A (Italy) – specialized in stainless steel

✅ Certifications & Standards

• UL Listed / FM Approved – required for fire protection systems

• ANSI / ASME B16.9 – US standard for dimensions and tolerances

• DIN / EN 10253 – European standards

• JIS B2311 / B2312 – Japanese standards

• ISO 9001 – quality management certification

• PED / CE – pressure equipment directive for EU compliance

⚠️ Key Considerations

• UL/FM approval is mandatory for fittings used in sprinkler and hydrant systems.

• Welding quality and beveling must match pipe schedule and thickness.

• Material traceability is critical in industrial and petrochemical applications.

• Brand selection depends on project specs, budget, and required certifications.

🔧 Siam Butt‑Welding Fittings – Professional Overview

Definition

Siam fittings are forged or welded components designed to connect, branch, or change direction in pressurized piping systems. They are produced under strict dimensional tolerances and international standards, ensuring durability and safety.

Application Areas

• Fire fighting systems – sprinkler, hydrant, and riser networks

• HVAC installations – chilled water and heating loops

• Petrochemical plants – high‑pressure fluid handling

• Shipbuilding and construction – robust piping connections in harsh environments

Product Types

• Elbows (90°, 45°) – change pipe direction

• Tees – branch connections

• Reducers – concentric/eccentric transitions between pipe diameters

• Caps – pipe end closures

• Special fittings – custom designs for specific layouts

Advantages

• High dimensional accuracy – strict tolerances and wall thickness schedules

• Wide size range – from ½” to 48”

• Durable materials – carbon steel, stainless steel, alloy steel

• Compliance with global standards – ANSI, DIN, JIS

• Superior mechanical properties – corrosion resistance and pressure fatigue strength

📊 Technical Specifications

Certifications

• Manufactured to international dimensional standards (ANSI/DIN/JIS).

• ISO 9001 quality management certified.

• For fire protection projects, check if specific UL/FM approvals are required (Siam fittings are generally industrial grade, not UL/FM by default).

⚠️ Key note: Siam fittings are a cost‑effective alternative to premium UL/FM brands like SHIELD or Benkan. They are widely accepted in Egypt and MENA for HVAC and industrial projects, but in strict fire protection jobs (sprinklers/hydrants), consultants may demand UL/FM certified fittings.

🔹 Bothwell Butt‑Welding Fittings – Professional Overview

Definition: Bothwell fittings are forged or welded pipe components manufactured in Taiwan, designed to connect, branch, or change direction in pressurized piping systems. They are recognized for high dimensional accuracy, strict quality control, and compliance with international standards.

Application Areas

• Fire fighting systems – sprinkler and hydrant piping networks

• HVAC installations – chilled water and heating systems

• Petrochemical plants – handling high‑pressure fluids

• Shipbuilding and offshore construction – durable piping connections in harsh environments

Product Types

• Elbows (90°, 45°) – change pipe direction

• Tees – branch connections

• Reducers (concentric/eccentric) – transition between different pipe diameters

• Caps – pipe end closure

• Special fittings – custom designs for specific layouts

Advantages

• High dimensional accuracy – precise tolerances and wall thickness schedules

• Wide size range – from ½” to 48”

• Durable materials – carbon steel, stainless steel, alloy steel

• Compliance with global standards – ANSI, DIN, JIS

• Superior mechanical properties – corrosion resistance and pressure fatigue strength

• Trusted brand – Bothwell is well‑established in Asia and MENA markets

📊 Technical Specifications

Certifications

• Produced under ISO 9001 quality management system

• Manufactured to ANSI/DIN/JIS dimensional standards

• Generally not UL/FM certified by default, so for strict fire protection projects (sprinklers/hydrants) consultants may require UL/FM brands like SHIELD or Benkan

⚠️ Key note: Bothwell fittings are considered high‑precision industrial fittings. They are widely used in Egypt and MENA for HVAC and industrial projects, and often accepted in fire fighting systems where UL/FM certification is not mandatory.
