Description

Weld Neck Carbon Steel Flange ASME B16.5 Class 150 SCH40 Hot Dip Galvanized

Product Description

These carbon steel flanges are manufactured in strict compliance with the ASME B16.5 standard, adopting high-quality carbon steel material, precision forging process, and hot dip galvanizing (HDG) surface treatment. Designed as Weld Neck (WN) type, they feature Class 150 pressure rating and SCH40 wall thickness, ensuring excellent corrosion resistance, good pressure-bearing capacity, and reliable sealing performance. Widely used in industrial pipeline systems requiring cost-effective, durable, and anti-rust connections.

Key Parameters

  • Material: Carbon Steel
  • Standard: ASME B16.5
  • Process: Forged + Hot Dip Galvanized (HDG)
  • Pressure Class: Class 150
  • Wall Thickness: SCH40
  • Type: Weld Neck (WN) Flange
  • Face Type: Raised Face (RF, standard)
  • Features: High strength, hot dip galvanized anti-rust, pressure resistant, forged structure, reliable sealing
  • Application: Water supply, drainage, oil & gas, chemical, construction, industrial piping systems

Application

Widely applied in water supply and drainage projects, oil and gas transmission pipelines, chemical processing plants, construction engineering, and general industrial piping systems. Suitable for connecting pipelines, valves, pumps, and equipment, especially in outdoor, humid, or mild corrosive environments, where the hot dip galvanized surface provides long-term anti-rust protection, ensuring stable operation of the piping system.

Product Advantages

  • Strictly complies with ASME B16.5 standard, ensuring dimensional accuracy, interchangeability, and consistent quality, meeting international export requirements.
  • High-quality carbon steel material and precision forging process enhance structural stability and pressure-bearing capacity, adapting to Class 150 working pressure and SCH40 wall thickness requirements.
  • Hot dip galvanizing surface treatment provides excellent anti-rust, anti-corrosion performance, effectively extending the service life in humid and outdoor environments.
  • Weld Neck (WN) design ensures firm welding connection with pipelines, uniform stress distribution, reduced leakage risk, and easy installation.
  • Cost-effective carbon steel material, suitable for large-scale industrial applications, balancing performance and budget.
  • Standard SCH40 wall thickness, compatible with common industrial pipelines, strong versatility.

Installation & Use

Before installation, check the flange surface, bolt holes, and sealing face for galvanizing layer damage, scratches, or contamination; clean the welding end and flange sealing face thoroughly. Use gaskets compatible with carbon steel and the working medium; tighten bolts evenly and symmetrically to ensure uniform pressure and reliable sealing. Conduct a pressure test after installation to confirm no leakage before formal operation. Avoid damaging the galvanizing layer during installation.

Precautions

Store in a dry, clean, and ventilated warehouse to avoid moisture, corrosion, and damage to the galvanizing layer; handle with care during transportation to prevent collision and scratch. Use within the rated pressure (Class 150) and temperature range; avoid overloading or improper installation. Professional welding and installation personnel are recommended to ensure the welding quality and galvanizing layer integrity.

Delivery

Ship within 7–15 working days after order confirmation; shipped by sea, air, or express according to customer requirements. A logistics tracking number will be provided promptly to facilitate order tracking.

Payment Terms

T/T, L/C, Western Union, PayPal; 30% deposit upon order confirmation, balance paid before shipment.

Packing

Plastic caps + anti-rust film wrapping + foam protection + plywood wooden case; shockproof, moisture-proof, and anti-scratch, effectively protecting the galvanizing layer, suitable for long-distance ocean transportation and international shipping.
