Hydraulic Pillar with Hot Rolled Seamless Steel Tube (GB/T17396-1998)
The GB/T17396-1998 outlines the specifications for hot rolled seamless steel tubes used in hydraulic pillars. According to this standard, the tubes can be used to produce hydraulic joint components, including support pillars, handrails and links. The standard applies both to tube materials and the finished components, and thus encompasses all aspects of the production and use of such materials.
In terms of the materials to be used for the manufacture of hot rolled seamless steel tubes for hydraulic pillars, the standard outlines the requirements in terms of their chemical composition, mechanical properties, dimensional characteristics and surface quality. In particular, in terms of the mechanical properties, the standard requires that the tubes possess good resistance to mechanical stress, impact, fatigue and corrosion. Furthermore, it states that the inner and outer surfaces of the tubes should be free from imperfections and must meet certain prescribed tolerance limits when measuring the diameter and wall thickness of the tubes.
In terms of the use of hot rolled seamless steel tubes for hydraulic pillars, GB/T17396-1998 provides detailed specifications for their design and installation. These include requirements for the minimum wall thickness and maximum allowable gap between welds and between tubes, as well as the minimum bend radius of the tubes. Furthermore, it also outlines requirements for the design of the tube joints and flanges, specifying mandated dimensions and tolerances.
When it comes to the strength of hot rolled seamless steel tubes used in hydraulic pillars, GB/T17396-1998 states that the tubes must be capable of sustaining a tensile stress of 345 MPa. In addition, it outlines the requirements for the testing of the tubes. This includes test methods for the measurement of changes in the tubes’ diameter, their bending properties, surface quality, and their resistance to fatigue, corrosion and impact.
GB/T17396-1998 also provides guidance for the packaging, transportation and storage of the hot rolled seamless steel tubes used in hydraulic pillars. In this regard, it outlines the requirements for the marking of the tubes, as well as the requirements for their covering and protection against weather conditions.
Overall, GB/T17396-1998 outlines the requirements for the production and use of hot rolled seamless steel tubes used in hydraulic pillar applications. It clearly outlines the specifications for these materials, as well as the requirements for their design, installation and testing. These terms make it easier for contractors and manufacturers to produce and use such materials efficiently and safely, guaranteeing the quality of their products and the safety of their use.
