Concrete is applied by wrapping a uniform layer while simultaneously wrapping reinforcing wire within the concrete coating for stability. The concrete is prepared in an automated batching plant using aggregates (e.g., sand, iron ore), cement and water.
21-11-2011· Concrete coating is intended to: Achieve the required negative bouyancy/submerged weight (due to Lateral and Vertical Stability) Provide an additional mechanical protection (if needed) and also can provide thermal insulation (if needed) To achieve the purposes stated above, the material of concrete weight coating for pipeline consist of: Cement Concrete Weight Coating is matriced by
Zero-slump concrete can be used for weight coating of steel pipes used for the underwater transmission of natural gas, primarily to provide negative buoyancy for the pipe sections. This concrete is prepared using heavyweight (iron ore) aggregates and typically has a water-cement ratio of 0.33.
Concrete Weight Coatings are applied to Offshore Pipelines. Concrete Weight Coating on pipes ensures that gas and oil pipelines will not float (negative buoyancy) ones they are installed in sea and protects them against collision damage. To achieve concrete with a high density, iron ore is added. Concrete Weight Coating is always steamcured.
ISO 21809-5 CONCRETE WEIGHT COATING(CWC) FOR OFFSHORE PIPELINE - ISO 21809-5 CONCRETE WEIGHTED COATING(CWC) Products, China Manufacturer. External concrete weight coating application is performed by "impingement" method. Concrete coating is applied by continuously throwing the concrete mix on longitudinally moving and rotating pipe with protective coating and
Economical heavy concrete weight coating (102) is used as a weight coating for submarine pipes (104). The economical heavy concrete weight coating (102) includes steel slag and iron ore as aggregate. Steel slag can contain iron and thus have a higher density than some other types of slag. By supplementing the steel slag with iron ore as aggregate, the economical heavy concrete weight coating
Jetek Nigeria has in depth knowledge of concrete weight coating. Depending on your choice we can use iron ore or granite as base aggregate to provide offshore and
Concrete weight coating (CWC) involves extremely high operational costs for coating materials (iron ore and cement). Therefore a controlled execution of the coating process from the start of production is essential. Bauhuis has in-depth knowledge of the process and brings experiences gathered over 40 years in designing concrete weight pipe

05-06-2014· In a preferred embodiment of economical heavy concrete weight coating, both steel slag and iron ore are used as aggregates. Other aggregates may also be used. In some embodiments, the economical heavy concrete weight coating includes 40-45% iron ore, 30-35% steel slag, 16-17% cement, 2-3% sand, and 5-6% water at the time it is mixed.
Heavy weight iron-ore is used as the main ingredient of the high density concrete mix for concrete coating of sub-merged marine pipelines which is transportation of petroleum materials like importing crude oil and domestic gas, desired heavyweight concrete is
By adding weight to the pipe, CWC helps keep movement and vibration down, prevents slipping and damage to the pipe, and protects the pipe from corrosion. With CWC, pipes are coated at the manufacturing facility with a special formula of magnetite-infused concrete. The iron ore not only makes for a heavier, smoother concrete product.
Heavy weight iron-ore is used as the main ingredient of the high density concrete mix for concrete coating of sub-merged marine pipelines which is transportation of petroleum materials like importing crude oil and domestic gas, desired heavyweight concrete is
The concrete weight coating system is typically used in conjunction with other coating systems such as FBE and 3LPP/E. Bayou uses various methods to avoid slippage between the concrete layer and anti-corrosion coating. These include adding a rough-coat layer or applying a 2-component epoxy adhesive to bond the concrete to the coated surface.
Concrete is applied by wrapping a uniform layer while simultaneously wrapping reinforcing wire within the concrete coating for stability. The concrete is prepared in an automated batching plant using aggregates (e.g., sand, iron ore), cement and water.
Adding MagnaDense to the concrete will make it heavier, however, the concrete is still fluid enough to be sprayed onto the pipelines. Compression concrete weight coating. Using this applying method, the pipe gets a concrete weight coating by rolling the heavy concrete with a
The concrete is prepared in an automated batching plant using aggregates (e.g., sand, iron ore), cement and water. The mix is applied on the pipe by impingement or compression while one or more reinforcing wire meshes are incorporated, depending on the required coating thickness. Pipeline Protection, Available Worldwide
