Project Highlight: Singapore Client’s Order for 90° Long Radius Elbows

Haihao Group successfully fulfilled an order for 90° long radius elbows (LR Elbows) tailored to meet the stringent requirements of ASME B16.9 standard. Here’s a breakdown of the specifications:

• Material: ASTM A234 GR.WPB (carbon steel, weldable grade)
• Size: 24″ Nominal Pipe Size (NPS)
• Wall Thickness: SCH STD (Standard) / SCH 20
• Standard Compliance: ASME B16.9 (dimensions, tolerances, and testing protocols)

These elbows, designed for low-pressure fluid systems, were crafted to ensure optimal flow efficiency and structural integrity in demanding industrial applications.

Uncompromising Quality Assurance: Full Suite of Inspection Reports

At Haihao Group, quality is non-negotiable. Every product undergoes multi-stage testing to guarantee compliance with international standards. For this Singapore project, we provided the following comprehensive reports:

Micrographic Examination with Photographic Documentation

Reveals material microstructure (e.g., grain size, inclusion rating) to validate mechanical properties.

Corrosion Resistance Test (ASTM G48)

Simulates aggressive environments (e.g., seawater, acidic conditions) to assess pitting corrosion resistance.

Hardness Testing (Rockwell/Brinell Methods)

Ensures material hardness meets ASTM A234 specifications for durability.

Charpy V-Notch (CVN) Impact Test

Measures toughness at low temperatures to prevent brittle fracture.

Ferrite Content Analysis

Critical for duplex/stainless steel grades to balance corrosion resistance and strength.

Positive Material Identification (PMI)

Verifies chemical composition via XRF/OES spectroscopy to eliminate material mix-ups.

Dimensional Inspection Report

Confirms adherence to ASME B16.9 tolerances for outer diameter, wall thickness, and bend radius.

Non-Destructive Testing (RT/UT/LPT)

• Radiographic Testing (RT): Detects internal flaws like cracks or voids.
• Ultrasonic Testing (UT): Identifies subsurface defects in welds.
• Liquid Penetrant Testing (LPT): Reveals surface discontinuities (e.g., hairline cracks).
