Haihao Group Ships ASTM A105 Fittings and Branch Connection Components to the UAE
Haihao Group has completed a new shipment of forged and threaded pipe fittings for a customer in the United Arab Emirates. The order combines ASTM A105 fittings, stainless steel components, branch connection fittings and threaded accessories in a range of sizes and pressure classes.
For UAE piping projects, component selection often depends on more than nominal size. Material grade, pressure rating, pipe schedule, connection type and dimensional compatibility all need to match the project specification. This shipment was prepared accordingly, with several products supplied in ASTM A105/A105N carbon steel and others in stainless steel grades such as ASTM A182 F316L and ASTM A403 WP316/316L.
Product Range for the UAE Order
The shipment includes threaded fittings, branch connection components, reducing fittings and socket-weld products. The specifications cover sizes from 1/4″ to 4″ and pressure ratings up to 6000 PSI or Class 3000, depending on the product.

Why ASTM A105 Is Widely Used for Forged Piping Components
ASTM A105 fittings are commonly selected for pressure piping applications where forged carbon steel components are required. ASTM A105 covers carbon steel forgings for piping applications, including fittings and other pressure-containing components.
In this UAE order, ASTM A105 and A105N are used for threaded tees, reducing couplings, plugs and branch connection components. The combination of forged construction and compact dimensions makes these components suitable for piping arrangements where reliable connections are required within limited installation space.
The A105N products in this order also include different configurations, allowing the customer to match the fitting with the required pipe schedule and connection arrangement rather than relying on a single standard configuration.

MSS SP-97 Branch Connections for Piping Systems
The order also includes branch connection components manufactured from ASTM A105N and ASTM A182 F316L. The specified MSS SP-97 fittings cover reinforced branch connection applications, with the actual run and branch dimensions selected according to the customer’s requirements.
MSS SP-97 addresses essential requirements such as dimensions, finish, tolerances, testing, marking and material for integrally reinforced forged branch outlet fittings. The current MSS SP-97-2025 edition covers butt-welding, socket-welding and threaded types.
For this shipment, Haihao Group supplied both carbon steel and stainless steel branch components, including a 3/4″ × 3″ ASTM A182 F316L item and several ASTM A105N configurations.
Stainless Steel Options for Corrosive Service
Carbon steel is not the only material represented in this order. The customer also specified ASTM A182 F316L and ASTM A403 WP316/316L for selected components.
The ASTM A182 F316L branch connection is supplied in SCH 80S, while the ASTM A403 WP316/316L concentric reducers cover SCH 40S and SCH 10S × SCH 40S configurations.
This combination gives the customer flexibility when designing piping systems with different material requirements across the same project. Material selection can be matched to the process medium, temperature, corrosion conditions and applicable project specifications.
Different Connections for Different Piping Requirements
One practical feature of this order is the variety of connection types.
The shipment includes:
- Threaded nipples and plugs
- Female-threaded equal and reducing tees
- Socket-weld tees
- Butt-weld branch connections
- Raised-face flanged branch connections
- Concentric reducers
This makes the order more than a standard fitting supply. It covers several connection arrangements that can be used in piping assemblies, manifolds and branch lines.
For example, the 1-1/2″ × 3/4″ and 3″ × 1-1/2″ reducers provide different transition configurations, while the threaded tees and couplings are supplied in compact sizes from 1/4″ to 2″.
Quality Control Before Shipment
For ASTM A105 fittings and other forged components, dimensional accuracy and material identification are important because small fittings are often installed directly into pressure piping systems.
Haihao Group checks the supplied products against the purchase requirements, including:
- Material grade and specification
- Nominal size and schedule
- Pressure class
- Connection type
- Machining and thread configuration
- Dimensional requirements
- Surface condition and marking
For products manufactured to specific standards, the inspection and documentation requirements can be coordinated with the customer’s project specification.
A Mixed Fitting Order Prepared for UAE Delivery
This UAE shipment demonstrates Haihao Group’s ability to handle mixed fitting orders rather than limiting supply to one product category. From compact threaded components to stainless steel reducers and reinforced branch connections, the products were selected according to individual size, material and connection requirements.
For buyers sourcing ASTM A105 fittings, stainless steel fittings, MSS SP-97 branch connections or custom combinations of forged piping components, Haihao Group can review drawings, specifications and material requirements before production.
