Join us for an informative webinar where we delve into the intricate details of pipeline bending and highlight essential considerations that every engineer, purchaser, and industry professional should know. In this session, we will cover various topics that are often overlooked but crucial to understanding the complexities of pipeline design and manufacturing.

Discover the nuances of required wall thickness calculation to AS 2885.1, where the thickness requirements differ from straight pipes. Unravel the intriguing dynamics of extrados and intrados thickness and learn how to specify minimum intrados and extrados thickness effectively, including corrosion allowances.

Gain valuable insights into manufacturing tolerances and understand what purchasers should request when ordering a bend. We'll clarify that adding tolerance is not the responsibility of the purchaser but rather the bender's duty to meet the specified minimum.

Explore the intriguing world of API 5L ERW pipe thickness under-tolerance and unveil why it is actually less than 10%. We'll delve into the dominance of weight tolerance over thickness tolerance, shedding light on practical considerations where it is commonly -3.5%.

Delve into the divergence between the definitions of ovality in AS 2885 and ISO 15590. We'll elucidate the conversion between these definitions, highlighting the typically double standard and the heightened stringency of ISO 15590.

Contemplate the safety and feasibility of cutting an induction bend within the bend itself and welding it to the next pipe. We'll discuss the risks involved, such as weldability, weld procedure validity, and dimensional compatibility, including out-of-roundness concerns.

Unlock the world of quality assurance (QA) activities with a focus on gauge plate checks. We'll walk you through the essential elements of these checks and provide an understanding of their significance in maintaining pipeline integrity.

Learn about the intriguing concept of proof bends and how they provide insight into the properties of pipelines without resorting to destructive testing. We'll explore the intricacies of conducting proof bends and clarify whether they require the same pipe heat or a piece from the same pipe length.

Dive into the realm of strain ageing and its impact on pipe properties when subjected to heat. Discover how professionals predict and account for these changes to ensure safe and reliable pipeline operations.

Finally, we'll challenge the conventional wisdom of fracture control for bends. Examine the logical reasons behind the lack of fracture propagation control for short-length bends and gain insight into the experimental validity of fracture propagation theories in this context.

Don't miss this opportunity to expand your knowledge and gain a deeper understanding of the critical factors surrounding pipeline bending. Join us for this engaging webinar and equip yourself with invaluable insights to enhance your pipeline design and manufacturing practices.
