Unions – RJT (BS4825 PT5)

When you purchase your hygiene tubes and hygienic fittings from DPL you can look forward to:

Exceptional standards

Our hygienic austenitic tubes and hygienic fittings meet the exacting standards set by the American Society of Mechanical Engineers (ASME) for tubing and fittings used in the pharmaceutical industry, namely ASME Bioprocessing Equipment (ASME BPE), and conform to ISO 9001-2015 manufacturing and quality standards.

Plus, all contact parts are manufactured from T316L quality materials. Sulphur is controlled at weld points to a 0.005% minimum and a 0.017% maximum to ensure high quality orbital welds. 

Comprehensive traceability

As part of our Quality Control, we check that all raw materials purchased conform to the Chemical Analysis stated on the Material Certificate — this is carried out by an independent laboratory. All materials are also traceable back to the original Material Certificates. To ensure full traceability of all materials to the original Material Certificate, we SFL mark all T316L products with an internal reference number in addition to their cast/heat number.

A wide variety of product options

Our extensive product range covers austenitic tubing sizes from 1/4” O.D. to 6” O.D. in tubing, weld end fittings suitable for orbital welding and clamp ended fittings. What’s more the tolerances on our weld ended products are suitable for closed head orbital welding, with tolerances on squareness and wall thickness complying with ASME BPE.

Whichever product you choose, you can look forward to a choice of finish — mechanical or electropolished on the internal diameter, and mill finished or satin polished on the outer diameter.

Professional packaging and certification

With your products carefully finished, they will be professionally packed — austenitic tubing is supplied with ends capped, sleeved in polythene and end heat sealed, while hygienic fittings are capped and heat sealed in polythene.

Your products will arrive accompanied by full material certificates, either with the goods or via email, or both if required. Where needed, we will provide a full quality dossier to cover project work.

Maximising your workflow productivity

Owing to the exceptional quality of our hygienic tubes and fittings, our tailored options, as well as bespoke solutions and ongoing support, you can look forward to improved workflow productivity. If something isn’t quite right with your product, our experienced team is here to help resolve the problem.

Certification

Certification for DPL Products

From the vast array of published standards there are a number that are key to each industry. The accepted way of confirming that the standard has been complied with is for the manufacturer or service provider to issue a form of certificate with the goods or service.

There are many types of certificate but typically they can be categorised as Certificates of compliance, Test certificates, Inspection certificates or reports and Certificates of acquired skill or attainment.

DPL is an assessed company to the ISO 9001:2015 Quality Assurance standard and certifies that its products meet the relevant standards the product was designed for and also where modifications are made to suit a specific purpose.   We provide a Certificate of Conformance with each order dispatched.   Our seal and gasket components are food contact safe and we provide certification for these that states the relevant FDA schedule number for the material.

Valve Test Certificate is available for all DPL supplied valves.   This will supply information on the materials used, the seal material and seal standards, the method of test and the test pressures, and the internal surface finish.   Component Material certificates for the product wetted surfaces of the valve are also available with this certificate.

EU safety law

A statement of compliance is normally a legal requirement evoked by a European Directive.   DPL issue these with every valve and actuator in line with the requirements of the particular commodity type along with our recommended valve installation procedures.

Some of the legislation affecting DPL products includes the Pressure Equipment Directive (PED), designed for pressure bearing products safety and the Machinery Directive that requires the design of the machinery is safe to operate and presents no hazard in operation.

DPL produces valves that comply with the electrical bias ATEX directive, for safety of operation in potentially explosive atmospheres which also seeks to prevent ignition through static discharge on non electrical products.

There are many other specialist certificates that have not been covered above.   If you require a particular approval certificate for the components we can supply for your installation please enquire at the time of order with your DPL Sales contact.

Quality

Stainless Fittings (SFL) and Dairy Pipe Lines (DPL) are manufacturers of a range of stainless steel fittings, valves and bespoke fabricated units for the bio-processing, pharmaceutical and food industries. The companies are regularly assessed to the ISO 9001:2015 Quality Management standard.

The products provided by the company meet the stringent statutory and regulatory requirements demanded by the marketplace.  Inspections and product tests are carried out at regular stages of manufacture allowing comprehensive quality records to be maintained. These records can then be used for analysis as part of our commitment to ongoing process and product improvements. As part of this process, bi-monthly reviews are in place to ensure the quality system continues to support our business objectives.

With the processes of the Quality Management System defined and implemented, one major role of the management team is to adapt these processes to meet changing requirements in the industry and to enhance the business wherever this results in a benefit to our customers.

Our initial contact with our customers is normally through the Sales team. Here your precise requirements are assessed and stock availability discussed with you in order to meet your needs. Where you require us to make use of our fabrication facility, we take the time to understand your exact requirements even further.
After being sure that your sales contact has a clear understanding of your requirements, we conduct a Contract Review Meeting to ensure that the entire team responsible for manufacturing your order are all clear on what is needed.
We will contact you where we need further information or where we need specific points being clarified. All agreements are documented so you can be sure we have your requirements on board.

Material traceability is of prime importance to us, and therefore our internal bespoke systems and material identification allows us to trace material back to its origin.

SFL and DPL offer a wide range of certification options to include Certificates of Conformance, Original Material Certificates, EP or Passivation Certs, Weld maps, Qualifications and Procedures to name a few. Just discuss your requirements with us – our Mission is your Peace of Mind.
