Stainless steel head manufacturer Which is better? So we have to be sure that through personal visits, all in Hebei Thai Tinto purchase stainless steel head users, all of them have praised Rio's comments on Thailand is very high, so we mention everyone Chang Extension of this company in Thailand to buy, the quality must be very good, but some manufacturers added value is high, but why we can not get the price it is selling infection have what I feel several factors. stainless steel head is a use to block stainless steel pipe products. After the pipeline is coming to an end, or at the two ends of a piece of tube welding head do two containers of a product. Similarly products are blind, caps, plugs and the like. The other is called stainless steel head: no straight edge stainless steel head, barrel spin edge, oval head, dished head, pale-shaped head, various sizes head spin side, stainless steel size head spin side, flat, hemispheric shaped rotating side, of spherical top. Specifications: Ф32MM-6000 MM thickness: 1MM-60MM stainless steel head size of the stress and the work factor in the martensite cooling rate area, shape, chemical composition of the material. The end result stainless steel head organizations stress that the surface tensile stress, the center compressive stress, and thermal stress exactly the opposite. Practice has proved that any of the workpiece during the heat treatment, as long as there is a phase change, heat stress and stress will occur. But the thermal stress on organizational changes in the past have produced stainless steel head, and the stress is generated in the organizational transformation process, the entire cooling process, the result of thermal stress and organizational stress combined effects, is actually present in the workpiece stress. Common standards: JB / T4746-2002 GB25198-2010GB / T12459-2005GB / T13401-2005 SH3408-1996 head quality is directly related to the pressure vessel of the long-term safe and reliable operation. The head of our existing standards, by structure type (oval, dish, cone), different forming method (stamping, spinning), which were developed, which not only result in different quality standard heads incomplete consistent anomaly, but also to the head of the selection criteria, the revised standard has brought some difficulties.
