Bend Restrictor Selection Guide MBR ID OD Standards

In the field of marine engineering, providing reliable bend protection for critical equipment has always been a key industry focus. As a professional provider of marine engineering protection solutions, we are releasing this selection guide to help customers scientifically choose the most suitable bend restrictor (BR) products.

Core Parameter Analysis: Understanding the "Technical Language" of Products

When selecting bend restrictors, the following core parameters require special attention:

Minimum Bend Radius (MBR) : This is the primary design indicator for our products, ensuring cables bend within a safe range and preventing damage from over-bending.

Inner Diameter (ID)/Outer Diameter (OD) Our products offer a variety of size options to ensure a perfect match with various cables and connectors.

Tensile Strength (TS)  : For different application scenarios, we provide multiple product series ranging from standard grade to heavy-duty grade.

Environmental Adaptability  : Our products use special material formulations, capable of withstanding a wide temperature range from extreme cold to high temperatures, and offer excellent corrosion resistance. Key standards include DNVGL-ST-0378 and API Spec 17L1.

Four-Step Selection Method: For More Precise Choices

Based on years of industry experience, we have summarized the following four-step selection method:

Environmental Assessment: Our technical team can assist customers in analyzing specific application environments (e.g., static, dynamic, S-lay, J-lay) and recommend the most suitable product series.

Size Measurement: We provide professional measurement guidance to ensure accurate selection of ID/OD.

Parameter Determination: Based on the customer's specific needs, we recommend products with the optimal MBR and required TS.

Solution Customization: For special requirements, we provide fully customized product solutions, including bespoke MBR and material specifications.
