Having three welding workshops in Poland, we can provide steel hose welding and pressure testing services.
Within the scope of our welding competencies Tubes International Sp. z o.o. was granted the following certificates:
EU Certificate of Conformity issued by Office of Technical Inspection (UDT) to confirm compliance with the requirements of Directive 2014/68/EU module A2 in terms of production of pressure equipment
Certificate confirming compliance with DNV requirements, issued by DNV GL
Certificate confirming compliance with the requirement of PN-EN ISO 3834-2:2007 standard, issued by Transportation TechnicalSupervision
Metal hose assemblies in 24h
Choose fast production but always made to the highest standards.
Quality of material and construction
All threaded fittings intended for steel hoses are designed and then machined by Tubes International. This production process guarantees consistent quality of materials and construction. Our lot tracking system allows to keep track of all fittings so we know exactly what material the fittings are made of.
Our welding engineers with IWE certificates of competence (International Welding Engineer) are responsible for welding process technology. Quality Control personnel with their NDT certificates of competence perform the inspection and testing of welded connections. That is why our hose assemblies are the best you get on the market.
We are pioneers in our field. We were the first to introduce welding quality system for hose assemblies according to EN 3834:2. Our welding workshop is approved by such notified bodies as: DNV-GL, TDT, UDT.
Constant development and introducing new technologies
Orbital welding used for the production of metal hose assemblies is the next important step to reach the highest production standards.
Production in 24H
Production in 24 h comprises metal hose assemblies of diameters up to 2” with the following fittings:
BSPT cone thread – type AF1
BSP thread, 60°cone – type AF2
90° BSP thread, 60° cone – type AF5
BSP thread – type AF7
BSP thread, flat seal – type AF14
Pipe fitting – type AF9 i AF10
Fixed flange – type AF3
Swivel flange – type AF4
Production in 24h concerns simple metal hose assemblies. We produce customized metal hose assemblies as well (then production time is longer than 24h).
