Application of bimetal composite pipe bimetallic connection

The double metal composite pipe follows the traditional mature installation method and technology of galvanized steel pipe, so it is convenient, reliable, hygienic and safe in use. According to the differences in the choice of materials for the base pipe and the inner liner, as well as the improvement of the manufacturing process, the scope of application is more and more extensive, and the economic, environmental, and social benefits brought about by it are even more pronounced. So, what are the applications of double metal composite pipes ? We will come soon

[bimetal composite pipe working principle]
The basic principle of bimetal composite steel pipe: The external base pipe is responsible for the pressure and the rigid support of the pipe, and the inner liner is responsible for the corrosion resistance.
Outer base pipe can use different diameters and thickness of carbon steel pipe according to the flow and pressure requirements of the transmission medium. Hot-dip galvanized steel pipe, straight seam welded pipe, spiral pipe, seamless steel pipe for low and medium pressure fluid transportation, high pressure boiler, seamless pipe steel pipe for oil cracking, line pipe, etc. The diameter can be from φ20-φ1020mm, and the wall thickness can be from 2.5-50mm.
The inner liner can use different corrosion resistant alloys depending on the chemical composition of the medium. Austenitic stainless steel 304, 304L, 316, 316L, copper-based alloys, nickel-based alloys, Hastelloy, titanium, titanium alloys, duplex stainless steels and other new high corrosion-resistant alloy materials. Liner tube wall thickness can be from 0.3-4mm depending on service life and welding process requirements.
【Application Field of Double Metal Clad Pipes】
1. Civil use:
Cold, hot water pipes, drinking water pipes, heating, solar energy, ground-source heat pumps; civil construction water supply pipes, water distribution pipes; air conditioning circulation pipes, fine decoration high-end commercial housing water supply pipes, etc.
2, industrial areas:
Oil and gas gathering and transmission pipelines, oil and gas well casing, sewage reinjection pipelines; chemical heat exchanger tube bundles; electric water desalination, desulfurization pipelines and so on. Metallurgy, seawater desalination, pharmaceutical chemicals, sewage treatment, new energy, food processing and other industries.
[Bimetallic connection method]

The majority of the outer base pipe is galvanized pipe, and the mature connection method of galvanized pipe is used:
1. Threaded connection (commonly referred to as screw connection), applicable to DN15-DN100, implementation of GB7306-2 and GB3287-1982 standards;
2, groove clamp connection, apply DN100 or more, the implementation of CJ/T156 standards;
3, flange connection, depending on the circumstances, the general use of DN100, flanges, etc. customized by the manufacturers, and coupled with a special silicone layer at the connection;
4, welding connection, according to the actual operating conditions using welding, the implementation of YB/T5092-2005 and JB/T4747-2002 standards, generally use three layers of welding, first argon-arc welding back cover, re-welding the transition layer, and finally manual arc welding filler cap .

Xiao Bian concludes: The above introduced the application fields of double metal composite pipes and hoped to help everyone. For more relevant knowledge, please continue to pay attention to this website information platform. Follow-up will present more exciting content for everyone.

STAINLESS STEEL PRODUCTS

Stainless steel is a corrosion resistant steel alloy with a minimum of 10% chromium. There are different grades and surface finishes of stainless steel produced to accommodate the environment in which the material will be implemented. Unlike carbon steel, stainless steel does not rust when exposed to air and moisture due to the sufficient amount of chromium present. The chromium creates an invisible passive film of chromium oxide that will not let oxygen attack the surface and prevents rusting of the iron base.

Yuhong Group is a stainless steel manufactory of more than 20 grades of Stainless Steel.
