CSAPL is a quality management company where a separate independent quality function exists to oversee all aspects and operations of the business; to ensure that quality is imbibed from the beginning till end of the value chain. The management in addition takes it upon itself to ensure that measurable and verifiable quality objectives are set through out the organization. Quality is assured from the time the raw material is inspected by a third party at the supplier’s site till the final product is transported to the customer. CSAPL strictly adheres to its quality policy which is known to each and every employee of the company.

The company has been holding ISO 9001 certification since Jan, 1997 and has been an API Monogram authorization holder since 1987. Modern and sophisticated equipment as well as highly qualified and experienced technical personnel have enabled the implementation of a formal quality programme across the entire organization.

Quality control involves inspection of raw materials at the mills to pre-shipment inspection and transportation delivery to the customer. It includes continuous inspection of manufacturing process, pipe handling and storage.


PIPE PLANT
Ensuring the use of modern technology, spiral welded steel pipes are produced at state of the art spiral weld pipe plant. Inspection and testing of bare pipes is carried out by employing sophisticated measuring and testing equipments, which includes Non-Destructive testing, Mechanical testing, Chemical Analysis and different dimensional measurements as per API 5L and client specific requirements.

On-line automatic ultrasonic testing units are used to check the complete length of the spiral seam as well as the entire width of the H.R Coil. Fluoroscopic inspection presents the entire spiral seam on visual display – for analysis of defects, if any. Each pipe is also hydrostatically tested as per API 5L specifications. In additions, an X-ray station takes radiographs of the weld seam at each pipe end. Every pipe is subjected to a rigorous check at the final inspection stand.

In order to keep pace with the changes in technical specifications and to meet the emerging requirement of sour gas transmission pipelines CSAPL has installed an automatic off-line ultrasonic testing unit. The off-line automatic ultrasonic testing unit will re-check the weld after expansion during hydrostatic testing which includes test systems for longitudinal weld defects as well as transverse defects and defects in the heat affected zone.

Great emphasis is placed on the specification of raw material quality requirements, raw material specifications are prepared in accordance with API standards as well as client’s specific requirements. CSAP ensures that it meets and exceeds all requirements even in cases when client specifications are more stringent than API standards. Further raw material is purchased from pre-qualified suppliers for which a stringent criterion has already been set through a vendor evaluation system.


COATING PLANT
We have added an acid wash facility to our coating plant. This ensures removal of traces of chloride from pipe surface in order to improve the bond between coating and pipe surface. Coating inspection and testing is carried out in accordance with international coating standards and test methods which include:
1.
Testing of raw material example determination of Gel time of epoxy power, melt flow index of polypropylene and other tests.
2.
Inspection of pipe prior to shot blasting.
3.
Checking pipe surface after shot blasting.
4.
Checking the blasted profile and depth of anchor pattern.
5.
Checking temperature of pipe prior to acid wash (Note: Acid Wash is carried out to remove traces of chlorides from pipe surface when specified by the client)
6.
Monitoring of Chromate Wash.
7.
Checking and monitoring of pipe temperature prior to Fusion Bonded Epoxy application.
8.
Checking and monitoring of pipe Bonded Epoxy thickness.
9.
Checking and monitoring the Copolymer Adhesive and High Density Polyethylene extruder temperature.
10.
Checking of time lag between application of Fusion Bonded Epoxy Powder and that of Copolymer Adhesive Layer and monitoring it to be within the gel time of Fusion Bonded Epoxy being used.
11.
Checking and monitoring thickness of Copolymer Adhesive and High Density Polyethylene/Polypropylene.
12.
Holiday detection of 100% pipe surface.
13.
Checking thickness, appearance and uniformity of coating and coating cutback.
14.
Checking final marking.
15.
Conducting peel test and Impact test.
16.
Conducting cathodic disbondment test.
17.
Inspection of the time of pipe storage and pipe loading on customer’s trailers.
18.
Testing for determining percentage elongation of High Density polyethylene/Polypropylene.
19.
Hot water soak resistance test
 
Radiographic inspection of weld seam
Hardness testing of material
   
Holiday testing of coated pipe
