AN ISO: 9001:2008 COMPANY
Quality Assurance at Pankaj Flexibles is of vital importance. Every stage of production is constantly monitored by a qualified team of QC Engineers. Pankaj Flexibles has complete in-house testing facilities for various types of tests, as per international standards specified for metallic flexible hoses.
Pankaj Flex strip wound metallic interlock hose are manufactured in accordance with generally standards ISO 15465 : 2004 & British Standard BS 6501- PART II.
ISO STANDARD: 15465-2004
This International Standard specifies the requirements for the design, manufacture and testing of four principal types of strip wound metal hose and hose assemblies, of which only one type is for pressure applications. The four are: single overlap, unpacked and packed; double overlap, unpacked and packed, the last of these having maximum allowable pressures of up to 40 bar, These hoses and hose assemblies may be supplied in nominal sizes from DN 6 to DN 500 and may operate at temperatures up to 600 °C dependent on materials of construction.
Pipe work – Strip wound metal hoses and hose assemblies (ISO 15465: 2004). Approved dated : 2004-04-16.
Our Interlock Hoses are under ROHS Compliance Test Certificate are Issued along with the material If required.
ROHS Compliance Definition:
The definition and aim of the ROHS directive is quite simple. The ROHS directive aims to restrict certain dangerous substances commonly used in electronic and electronic equipment. Any ROHS Complaint component Tested for the presence of Lead (Pb), Cadmium (Cd), Mercury (Hg), Hexavalent chromium (Hex-Cr), Polybrominated biphenyls (PBB), and Polybrominated diphenyl ethers (PBDE). For Cadmium and Hexavalent chromium, there must be less than 0.01% of the substance by weight at raw homogeneous materials level. For Lead, PBB, and PBDE, there must be no more than 0.1% of the material, when calculated by weight at raw homogeneous materials. Any ROHS compliant component must have 100 ppm or less of mercury and the mercury must not have been intentionally added to the component. In the EU, some military and medical equipment are exempt from ROHS compliance.
A test of attributes that are assessed to ascertain the quality of our range Metallic interlock Flexible Hoses & Conduits:
- Size & Dimension
- Smoke Test
- Burst Pressure
- Raw material Composition
- Crushing Test
- Corrosion Resistance
- Temperature Resistance
- Pressure Bearing Capacity
- Flexibility tests
- Mill Certificates are issued by the steel mill certifying chemical composition & mechanical properties of both Stainless & galvanized Steel .
- Our Interlock Metal Hoses & Conduits are Under ROHS Compliance.
- Third party Inspection available when required.
Every Strip wound Interlock Pressure & Exhaust hose assembly is tested hydraulically according to required working pressure in different sizes before dispatching. Smoke Test is also carried out whenever necessary to detect the leakage in exhaust hoses. All raw material used in the manufacture of interlock hoses, and end-connections undergo rigid inspection by qualified engineers to ensure highest quality standards produced gives the best performance for many years.
Besides stringent in-house control of quality, raw materials are sourced only from reputed manufacturers and these are regularly counter checked from external independent agencies for physical, chemical and metallurgical properties.
Where a general material certification is required, Pankaj Flex Shall provide letter of Conformity, Which shall confirm the grade & strip thickness of materials is used in manufacturing strip wound interlock hoses in both Stainless Steel & Galvanized Steel.
