Polyurethane Bend Restrictor for Petroleum Pipeline
Polyurethane bend restrictors are essential for safeguarding oil and gas pipelines,due to its high hardness, superior impact resistance, low temperature stability, and ease of production.The bend limiters made by Philson can effectively reduce the bending deformation of pipes and raise pipeline safety and dependability by fulfilling these crucial technological requirements.
Polyurethane bend limiter plays an important role in oil and gas pipeline protection, especially in situations where pipe bending deformation needs to be limited. For this static application, the technical require a hardness of 80-85 Shore D to ensure adequate support and stability. Each bend restrictor section needs to be able to withstand forces between 300 kg and 1 ton to cope with a variety of possible external loads.
Apart from the hardness and load-bearing ability, polyurethane bend limiters must fulfill further essential specifications:
High Hardness and Modulus: These are essential characteristics to guarantee that the bend restrictor can successfully restrict the pipe's bending deformation. When exposed to external forces, polyurethane material with a high modulus and hardness may retain its shape and resist deformation.
Outstanding Impact Resistance: During operation, oil and gas pipelines may be exposed to external shocks like earthquakes and soil movement. In order to shield the pipe from harm, the bend limiter must have excellent impact resistance.
Excellent Impact Resistance: oil and gas pipelines may be subjected to external shocks during use, such as earthquakes and soil movement. Therefore, the bend limiter needs to have excellent impact resistance to protect the pipe from damage.
Maintain Physical Properties at Temperatures Below 70°C: Polyurethane materials need to maintain good physical properties at lower temperatures to ensure that they still work effectively in cold environments. This requires the material not to harden or become brittle at low temperatures, and to maintain sufficient flexibility and elasticity.
Easy Processing: In order to facilitate production and installation, polyurethane bend limiter needs to be easy to process. This requires materials to be easy to cut, form and install to increase productivity and reduce manufacturing costs.
Defective Parts: In order to ensure the quality and reliability of the product, the bending limiter should avoid defects in the production process, such as bubbles, cracks, etc. This requires strict control of the production process and quality control processes to ensure that every part meets the standards.
