CARBON BLACK
EXPANSION JOINTS

Expansion Joints for carbon black plants are installed in several critical locations. Expansion Joints have many applications in carbon black plants, where the process involves high temperatures, varying thermal loads, dust/particulate as well as abrasive media. These operating conditions set high demands for the components installed in the application, including the Expansion Joints. When designed correctly for the application, Expansion Joints provide long-term durability and reduce maintenance, making them the ideal choice for carbon black plants worldwide.

Applications:

Reactor and furnace ducts
Cooling and filtration sections
Air preheaters
Flue gas emission control systems
Steam and utility piping
Heat exchangers

Design expertise:

High pressure
High temperatures
Special Expansion Joint design
Special tests
Special media compositions
Special material requirements

SPECIAL INSULATED EXPANSION JOINTS

CASE STORY

Belman has designed, manufactured and supplied four special hot combustion airline Expansion Joints for installation at a producer of carbon black in Italy. These Special Insulated Expansion Joints are designed to operate at extremely high temperatures (950°C). As Carbon black is produced at extremely elevated temperatures the media can easily reach +900°C during operation. Insulation of the Expansion Joints would play a key role in ensuring that the prevailing safety factors could be met and at the same time, keep the bellows skin temperature at an acceptable low level.

CARBON BLACK EXPANSION JOINTS

TECHNICAL DESCRIPTION

TYPES & DESIGN

The Expansion Joint types and designs applied in carbon black plants cover both standard catalogue Expansion Joints as well as customised Expansion Joints designed for the exact application. However, Belman mainly sees the following types of Expansion Joints used in this application:

Custom Expansion Joint solutions for carbon balck
As Expansion Joints are used in various applications in carbon black plants and for a wide range of operating data, the design and features of the Expansion Joints can vary greatly from project to project. Belman is highly specialised in finding and designing the best custom solution for the client and the application in question.

How we do

MATERIALS

Expansion Joints for carbon black applications are made from many different steel and metal types depending on the point of installation and the operating parameters. In many cases the Bellow is made from higher alloys such as Incoloy or Inconel. Belman can design and manufacture Expansion Joints for the carbon black from:

All austenitic stainless steels including 1.4571 (AISI 316Ti), 1.4404 (AISI 316L), 1.4541 (AISI 321).
1.4878 (AISI 321 H)
1.4845 (AISI 310 S)
Inconel 625
Incoloy 825

ADVANTAGES

QUALITY & TESTS

Belman is known for high quality products and therefore our quality control is a fundamental part of our business. All processes during production designed by the Belman quality engineers, is strictly follow and implement according our procedures and instructions and carefully inspected by Belman quality inspectors. All checks and inspections are done according to the strict prevailing Belman quality control procedures which is part of the Belman ISO 9001 quality management system approved by DNV.

ITP & Test
Inspection test Plan generated by the quality management system makes sure that each step of manufacturing has the appropriate inspection points such as Hold and Witness points.

Based on manufacturing code, project specification, application, media, and eventual ship classification rules Belman performs a large variety of quality tests including destructive, non-destructive testing and proof testing. All tests can be witnessed by the 3^rd part based on the customer and classification requirements.

Destructive test: such as life cycle test and burst test to validate the design, i.e., vessels and offshore platforms
Non-destructive test such as Visual testing, dye penetrant test, Radiography examination, Magnetic testing, ultrasonic testing, hardness testing and PMI for all applications
Proof tests: leak test with air, leak test with helium and formier gas, hydrostatic pressure test for all application
