Geotextile Pipeline Weight

Geotextile Pipeline Weight

 

 


Heshan geotextile pipeline weight is a series of ZDPS pipeline anti buoyancy control products including U1 type, U2 type, U3 type and U4 type. Introduce the latest advanced pipeline laying technology; we adopt environmental protection materials with special production engineering,approved patent certificate.


U1 geotextile pipeline weight

● Application scope
When the pipeline traverses the river, lake, marshland or swamp, the buoyancy will arise; the ZDPS-U1 geotextile pipeline weight (patent number:ZL 2006 2 0157792.4,passed GB/T19001-2008/ISO9001:2008 certificate of quality management system cetification,API Specification Q1,SGS test report)is a kind of product to control the pipeline buoyancy to avoid pipeline floating and ensure the smooth operation. 
 

● Features
Fast construction speed
The gravel can be obtained and filled at site, installation process is simple and ensures good construction effect, which simplifying the construction steps and shorten the construction time;
 

● Reducing construction cost: 

Without too much heavy equipment for installation which saves the equipment cost.

● Safety, environmentally protection, and coating protection:
The material is polypropylene which is anti-corrosive, durable, and able to endure acid and alkali, and no pollution to water. The pipeline weight is firmly pressed onto the pipeline with maximum area in contact with the pipe. It is non-biodegradable,the permeability of the material dose not impede cathodic protection, the key performance parameter cannot be changed within 40 years.

U2 geotextile pipeline weight

● Application scope
When the pipeline traverses the river, lake, marshland, or swamp, the buoyancy needs to be controlled. The pipeline weight (patent number:ZL ZL 2010 2 0208673.3,passed GB/T19001-2008/ISO9001:2008 certificate of quality management system cetification,API Specification Q1,SGS test report)is used in the situation which is not suitable for heavy equipment. 

● Features
1. The single bag is “U” type; the filling material is composed of small sandbags. Easy to place on pipe; free standing after filling;
2. Hooks can be removed from top of ditch.
3. Super strong double layer woven polypropylene material; Geotextile material will not harm pipe coating; cathodic protection is not restricted.
4. Within the constructiong scope, allowable range, directly fill with excavator instead of special filling machine.
5.Every single bag weight is up to 6-8 tons to improve pipeline safety buoyancy factor.
