Pipeline Saddle Bag Weights

pipeline negative buoyancy bag weight

  

HeShan Negative Buoyancy bag weight, made of Non-toxic pollution-free and

enviromentally friendly geotextile fabric with special producing technology, is a ZHYD's

patented system, which is one of the the most advanced technologies for pipe-laying in the

world , providing an effective, environmentally friendly and economical solution to your

pipelines weighting requirements.

Heshan bag Weights are the replacement of the traditional pipelines weighting such as

cement press products or concrete coating. Heshan bag weights can be used on all types of

pipelines , both steel and plastic, including gas, oil,water and coal gas, crosing rivers, lakes,,

foreshore,swamp,marsh, etc. for buoyancy control. It has the following advantages:

 

 

Fast to construction  

 1. Installation is simple. Fill the Heshan bag weights with gravel from a local source,distribute 

    along the right of way, lower over the pipeline, and back-fill.

 2. the bags can be filled up and deliverred to the site Within three days.

 3. No extra trench depth required. Less trench dewatering required.  construction period is    

     shortened.

 

 Construction cost is cut down

 1. Fill the Heshan bag weights with gravel from a local source, handling and transporting

     costs are saved.

 

 2. no heavy-duty equipment for hoisting, so equipment cost is saved. 3. Heshan 's "effective weight" under water often exceeds that of equivalent concrete weights or cement press products due to less water being displaced. for certain length of pipe, less weighting is required, so the procurement cost is cut down. 4. Leftover Heshan bags can be folded up and put on a shelf until your next project. Safety,Environmentally friendly and Coating protection:1. Heshan bag is purely made of polypropylene fabric, with features of corrosion-resistant ,anti-acid, non-pollution to water quality, which is a kind of reinforced  material with high durability. 2. Heshans non-biodegradable polypropylene fabric is filled with local gravel, so it is as permeable as the ballast used to fill it, allowing groundwater and cathodic protection an easy path. 3. Heshan bag weights are a soft buoyancy control, allowing the pipeline the ability to move slightly while still maintaining negative buoyancy and coating protection. 4. Heshan 's "effective weight" under water often exceeds that of equivalent concrete weights or cement press products, and the weight tilting problem is avoided..

Langfang Zhongyide Petroleum & Gas Equipment Co., Ltd.(Hereinafter say ZHYD) is a leading company in the industry in the pipeline accessories. Our products such as the HeShan geo-textile fabric negative buoyancy bag weight is a patented system of top-loading, gravel filled compartments that straddle a pipeline to achieve buoyancy control; the patented series insulators are patented products that are universally applicable in the installation of pipelines when the carrier pipe runs inside a casing; and the Cathodic Protection Test Piles are patented that are used for the Cathodic protection for the buried steel-pipeline of natural gas, LPG, oil, product-oil, coal gas, chemical plant, Hydraulic Engineering and Water supply engineering. Besides,we have other products such as MMO Wire Anodes,Anodes scarifies,Impressed current Anodes,Industrial Scientific Flammable gas testing series,Solid Sate Decoupler and so on.ZHYD also provides pigs that can be used for all kinds of oil, gas, water and new pipelines to remove the deposites and contaminants from the pipe.
