Seamless steel pipe in the standard (such as API5L, ASTMA106, etc.), there are fixed-length and variable-length, and some special items require length, but also for storage and transportation neat, but most of them are not fixed, because the production process due to Wall thickness, billet, the process is dynamic, inevitably make the length of finished products are different, if the length of delivery, it will result in part of the short-waste, many need to cut more pipe, resulting in waste, from the perspective of the use of Look, the pipes are generally used as pipelines (welded one by one), length is not necessary. The steel pipe knowledge provided by
Rock wool board, also known as rock wool thermal insulation decorative board, Stone Wool Board for Heat Insulation, is an inorganic fiber board made of basalt as the main raw material through high temperature melting processing. It was successfully tested in June, 1981. Rock wool board is a new type of thermal insulation, flame-proof and sound-absorbing material.Rock Wool Board is widely used in petrochemical, textile metallurgy, power transportation, construction agriculture and other fields.
The artificial inorganic fiber made of rock wool board by high temperature melting process has the characteristics of light weight, small thermal conductivity, heat absorption and incombustibility. The initial development is a common type of application in construction, which is mostly used in industrial buildings. It should meet the requirements of "Application Types and Basic Requirements of Building Thermal Insulation Materials". Rock wool is a kind of external insulation material. When the market share of 90% of the organic thermal insulation materials is stagnant, rock wool, as an inorganic thermal insulation material for exterior wall, has ushered in an unprecedented market opportunity.
