How to Pack Forged Steel Olets?

Before packing, we will do the marking on outlet fittings body which including size, pressure, standard and Heat No. After that, surfaced the forged steel olets with anti-rust oil which against rust during the shipment.

Then the workers began to sleeve SS 304 Threadolets BSP into plastic bag individually, and put them in cartons & wooden cases, finally bundled wooden cases with nylon rope.

Clear labels are tagged on the outside of the package for easy identification of the quantity and product I.D. great care is taken during operation and transportation.

Inspection Process of Stainless Steel Threadolet

1. Visual the surface of threaded olet.
2. Check the marking ‘ 1″ 3000# SS 304 BSPT MSS-SP-97 Z168″
3. Measure dimensions. Such as run outlet dimension, branch outlet dimension, wall thickness.
4. Test the chemical properties of stainless steel threadolet.

Advantages of Threadolet

Easy Installation: Branches are directly connected via threads, eliminating the need for welding and reducing installation time.

Convenient Maintenance: Easy to disassemble and reassemble, ideal for pipeline systems requiring frequent maintenance.

Cost-Effective: Suitable for small-diameter branches, saving on welding and installation costs.

Versatility: Widely used in industries such as petroleum, chemicals, power, and shipping.

Application Areas
