Application of Weldolet，Sockolet & Threadolet
- 90° Weldolet is often used in high-pressure and high-temperature applications such as in the oil and gas, petrochemical, and power plant industries.
- 90° Threadolet is suitable for low-pressure applications and situations where welding is not feasible or required, commonly used in water, air, or other low-pressure fluid systems.
- 90° Sockolet is typically used for socket welding in small-diameter pipes and high-pressure and leak-resistant applications.
- 45° Weldolet is used in space-constrained systems or where branches must be set at a specific angle, such as in certain process piping or HVAC systems.
- 45° Threadolet is suitable for low-pressure systems requiring a 45-degree branch connection without welding, such as compressed air or water distribution networks.
- 45° Sockolet is suitable for applications requiring a strong, leak-proof connection in high-pressure piping systems.
Advantages of Weldolet Sockolet Threadolet
- High Strength and Durability
- Reduced Stress Concentration
- Versatility for Various Applications
- Flexibility in Installation
- Cost-Effective
The Materials of Weldolet，Sockolet & Threadolet We Can Provide
SSM’s Olets are manufactured from controllable raw materials with strict quality control. We commonly supply fittings made from the following materials:
Carbon Steel Weldolet Sockolet Threadolet
SSM commonly provides olets including ASTM A105, A350 LF2 (for low-temperature applications), and A234 WPB. These fittings provide good strength and toughness, making them suitable for use in general piping systems, including those with moderate pressure and temperature.
Stainless Steel Weldolet Sockolet Threadolet
SSM commonly provides stainless steel olets including ASTM A182 F304, F316, F321, etc. They offer excellent corrosion resistance, high strength, and durability, ideal for applications involving harsh environments, including those in the chemical, petrochemical, and food processing industries.
Alloy Steel Weldolet Sockolet Threadolet
SSM commonly provides alloy steel olets, such as ASTM A182 F11, F22, F5, F9, etc. They are designed for high-temperature and high-pressure applications, providing superior mechanical strength and resistance to corrosion and oxidation. Commonly used in power plants, refineries, and petrochemical facilities.
Nickel Alloys Weldolet Sockolet Threadolet
SSM commonly provides nickel alloy olets such as Inconel 600, 625, 718, Hastelloy C276, Monel 400, and K500. They are known for their exceptional resistance to high temperatures, corrosion, and oxidation, making them suitable for applications in extreme environments like offshore drilling, chemical processing, and aerospace industries.
