Chinese Bend Restrictor for Optimal Hose Protection
The bend restrictor is mainly designed to protect the hose, reducing the excessive bending of the pipeline hose, which increasingly become the optimal choice for protecting the hose in the ocean.
The Development of Hose
As the world's demand for energy continues to increase, efforts to extract oil and gas resources from the ocean are also increasing. In the process of energy mining and transportation, composite hose has been more and more widely used for its advantages of strong designability, corrosion resistance, easy bending, easy laying and recycling, and more economical and practical development. In the development of deep sea and marginal oilfield, the application of composite hose has gradually become a trend.
Bend Restrictor Operating Principle
Composite hoses are usually connected with rigid structures such as subsea riser , pipeline terminal or wellhead structure. Excessive bending of composite hoses may occur at the joint, which will cause serious damage to the pipeline and affect normal production operations. Therefore, a bend limiter is usually installed on the composite hose connected to the rigid structure to prevent excessive bending and thus avoid damage to the pipe.
Bend Limiter Application
The bending limiter is mainly used for static application, less for dynamic environment, whose design is more complex, need to consider various load conditions. At present, the bending limiter on the market is made of polyurethane and ball ground cast iron, which both occupy a certain market. The spheroidal-graphite cast iron bending restrictor has low cost efficiency, strong impact resistance and can withstand high loads. Polyurethane bending limiter is light weight and strong corrosion resistance.
Both polyurethane bending limiter and ductile iron bend restrictor provide protection for Marine hoses. A polyurethane bend limiter is a optimal option in the long run.
