Wedge Wire Reactor Internal Scallop for Oil Refining

The wedge wire reactor internal scallop is an engineered screen component installed inside a fixed-bed reactor. It is typically mounted along the inner wall and functions as a flow distributor or collector. 

These wedge wire scallops are designed to enhance the performance of catalytic reactions by evenly distributing gas and liquid phases through the reactor bed. The wedge wire design offers strength, durability, and precise open areas for optimal flow management.

Why Use Wedge Wire Technology in Scallops?

The wedge wire, also known as Vee wire or profile wire, is a stainless steel wire with a V-shaped cross-section. When applied in reactor scallops, this material offers several advantages:

• High strength and load-bearing capacity under high pressure and temperature conditions.

• Excellent corrosion resistance, especially in aggressive chemical environments.

• Precise slot openings prevent clogging while maintaining ideal flow rates.

• Long service life due to its robust mechanical properties and resistance to fouling.

These characteristics make wedge wire ideal for manufacturing internal scallop systems used in oil-refining and petrochemical reactors.

Design and Materials of Wedge Wire Reactor Scallops

Wedge wire scallops are custom-fabricated using stainless steel 304 or 316, depending on the operating environment. Designs often feature laser-welded V-shaped wires on a support structure, ensuring uniform flow distribution across the catalyst bed. The anti-clogging nature of wedge wire helps maintain continuous operation even under challenging conditions.

In many applications, scallops include perforated inserts or support grids that further enhance mechanical stability. These inserts also assist in retaining catalyst media and preventing bypass or channeling, which can reduce reactor efficiency.

Reactor Scallop Applications in Oil & Gas and Petrochemical Industries

Wedge wire reactor scallops are commonly used in:

Hydrotreating and hydrocracking reactors

Downflow fixed-bed reactors

Catalyst support systems

Petrochemical and chemical processing vessels

Maintaining consistent fluid distribution and avoiding pressure drops are key in oil refining. These reactor scallops are often part of a larger reactor internal system, including support grids, center pipes, hub lateral distributors, and bed limiters.

Benefits of Using Wedge Wire Reactor Internal Scallops

Improved flow distribution in catalyst beds

Enhanced reactor efficiency and uptime

Custom design flexibility for different vessel sizes and geometries

Easy installation and replacement

For companies aiming to improve the performance of their refining units, integrating wedge wire internal scallops into their reactor design provides a cost-effective and highly efficient solution.
