We have a first class labortary, where mechanical, chemical and metallographic examinations can be undertaken. We also have advanced online ultra-sonic testing equipment and hydrostatic tester. We adopt strict quality control according to international standard.Testing played a necessary role in production and after production. We use high-quality facilities and a complete set of testing system such as X-ray flaw detectors, ultrasonic flaw hydrostatic pressure testing machines, tensile testing machines, metallographic analyzers, physics and chemistry laboratories and other detection systems. Our high-quality production testing procedures enable our production and testing to meet the required standards and to satisfy our customers.NoNameApplied location1Raw material ultrasonic testing deviceSteel plate detection2In-line ultrasonic testing deviceWeld seam detection3Flattening testing deviceTechnology testing4Hydraulic testing deviceFinishing section5Off-line ultrasonic testing deviceWeld seam detection6Pipe ends auto ultrasonic testing devicePipe end detection7Weighing equipmentFinishing section8Microscopephysical and chemical inspection laboratory9Spectrographphysical and chemical inspection laboratory10Universal test machinephysical and chemical inspection laboratory11Charpy impact test machinephysical and chemical inspection laboratory12DMTT Drop-testing machinephysical and chemical inspection laboratoryProduction processRaw material: hot rolled steel coil Technology: Length: 6-18 m (as standard and special lengths up to 53 m)Painting and packingERW Round Steel Tube and Pipe Surface protect: varnish painting(common protect), 3LPE (anti-corrosion coating) Ends type: PE(plain ends), BE (bevel ends) Pipe ends protect: plastic ends cap, pipe ends protector DeliveryERW Round Steel Tube and Pipe Encasement is done by our experienced forklift and crane driver in our factory.ApplicationERW Round Steel Tube and Pipes are used in various engineering purposes, fencing, scaffolding, line pipes etc.
