Certificates Certificates – Watani Composites

“Al-Watani Composite Group is the only ISO 9001 certified pipe & manhole manufacturer in the world“

ISO 9001

ISO is the International Organization for Standardization.
Its accredits and certifies Companies to ensure that they:

• Maintain a set of procedures to cover key processes

• Monitor manufacturing to ensure a quality product

• Keep proper records

• Check outgoing product for defects and take correct

action.

• Review processes and the entire quality system

regularly for effectiveness.

This certification ensures that a business delivers what it is supposed to deliver to its customers. When standards such as ASTM and DIN exist, these are the benchmarks for quality.

The development of pipes in polymer concrete dates back to the early 1960’s, however the technology had not developed significantly until recent years with the advancement in thermoplastic polymer resins. Consisting of up to 90 quartz tic, oven dried fillers, including mineral sands and grit with a grading curve of 0 to 16mm, with polyester resin as a bonding agent. Cement is not used; instead the polyester resin brings about the bonding between the fillers after curing and gives the pipes the additional positive properties of elasticity and resistance to fracture and chemic attack. Polyester resins, used as thermosetting bonding agents, are according to the requirements for the chemical resistance of the effluent to be transported. Al Watani has been involved in the manufacture of polymer resin based products for over 20 years and has an enviable reputation within the region for its innovative approach to new technology and manufacturing processes.

Typical properties of the finished product are

	Compressive strength: 100 to 120N/mm² Modulus of elasticity: 28000 N/mm² Tensile strength: 6 N/mm² Ring bending tensile strength: 16 N/mm² Ring fatigue strength: 6 N/mm² Absolute wall roughness: 0.1 mm²
