Vaishali Metals
The Standard length is 5m , but can be cut to a specified length. The tube is available in seven different levels of temper so that any desired temper can be chosen according to application for which it is used
Vaishali Metals which was initially started with the main objective of manufacturing Fine Bore Copper & Copper Alloy Capillary Tubing as per the existing ASTM standards to cater the requirements of General Engineering , Instrumentation, Refrigeration and Air-conditioning Industry ,has come a long way.

In 1992,VMPL started supplying Copper Tubing and Capillary Tubing to various Companies.

The company has been constantly upgrading technology, Conducting research & development has added various testing equipment to its laboratory. Recently under the able guidance of USA based company Whirlpool Corporation. Vaishali Metals has developed Copper Capillary Tubes which are compatible with Non CFC refrigerant i.e. R-134a an environment friendly refrigerant under the Montreal Protocol for prevention of ozone layer .Foreseeing the competition and with a view to enter and consolidate their position in the global market ,Vaishali Metals applied for ISO 9002 certification. Under the dynamic leadership of Mr.S.K.Papriwal ,TQM techniques, teamwork of fully motivated staff members, the company received its ISO 9002 certification in May 1999 from the globally reputed Underwriters laboratories(UL) Inc. U.S.A.

The company has ambitious development plans including exports to U.S.A., Africa and the middle East countries etc under the chairmanship of Sandeep Papriwal.
