Saigao Steel casing pipe Saigao Steel casing pipe, also known as encasement pipe, is most commonly used in underground construction to protect utility lines of various types from getting damaged. Such damage might occur due to the elements of nature or human activity. Saigao Steel casing pipe is used in different types of horizontal underground boring, where the pipe is jacked into an augered hole in segments and then connected together by welding or by threaded and coupled ends, or other proprietary pipe connectors such as the interference-fit Permalok interlocking push-on joint. The Saigao Steel casing pipe can also be set up and welded into a "ribbon" and then directionally pulled through a previously drilled hole under highways, railroads, lakes and rivers Saigao Steel casing pipe protects one or many of various types of utilities such as water mains, gas pipes, electrical power cables, fiber optic cables, etc. The utility lines that are run through the Saigao Steel casing pipe are most commonly mounted and spaced within the Saigao Steel casing pipe by using "casing spacers" that are made of various materials, including stainless steel or carbon steel and the more economical plastic versions. The ends of a Saigao Steel casing pipe "run" are normally sealed with "casing end seals", which can be of the "pull-on" or "wrap-around" rubber varieties. Saigao Steel casing pipe is also used in the construction of deep foundations. Specification Saigao Steel casing pipe generally has no specific specifications, other than the need for the material to be extremely straight and round. In some areas A.S.T.M. specifications may be required by project engineers. The specification most commonly called for is A.S.T.M. 139 Grade B. This specification gives parameters for minimum yield and tensile strength of the steel pipe being used for casing, and tolerances of straightness and concentricity. Saigao Steel casing pipe is often specified as ASTM A-252 which is a structural grade material that does not require hydrostatic testing and the inspection requirements are not stringent and it usually costs less than other grades such as A-53, A-139 or API 5L. Used natural gas line pipe is also used as casing on many projects because it is often reclaimed in very good condition and can offer a significant cost savings when compared to new steel pipe. Used pipe is most likely to not have any testing data associated with it and is generally used when the only required specification is a given diameter and wall thickness of Saigao Steel casing pipe.
Our products subjected to heat treatment, thus improve the hardness and toughness, can reduce consumption for buyers
We set up a professional technical team with the cooperation of research institutions, colleges, and universities. For instance, chinese academy of sciences are our direct cooperator, professor mr bern klein university of british columbia, canada is one of our team members. 1.Material: b2, b3, bu 2.Surface hardness: hrc58-65hrc, volume hardness hrc56-63. 3.The impact toughness of our grinding balls is more than 18 j / cm2. 4.The actual broken rate
Forged grinding ball features and advantages: 1. Surface hardness of up to 60hrc 2. High volume hardness as large as 55hrc to 60hrc, uniform hardness distribution 3. High impact toughness of greater than 12j/cm² 4. Low breakage rate, peel fragmentation resistance property of over 20000 times 5. Actual breakage rate not greater than 1% and close to 0
Our cast iron grinding balls can be divided into three categories including the high chromium type, medium chromium type and the low chromium type. 1. The quality index of the high chromium type The chromium content of the high chromium type product is greater than or equal to 10.0%. And the carbon content is between 1.80% and 3.20%. It is required by the national standard that the hardness of the high chromium type product must be no less than 58hrc, and that the impact value should be greater than or equal to 3.0j/cm. This type of product must go through the hot quenching and the tempering treatment to come up to the hardness. Currently at home, there are two quenching methods for this type of product including oil quenching and wind quenching. If the tested hardness of this type of product is below 54hrc, then it shows that the quenching treatment is omitted. 2.The quality index of the medium chromium type The medium chromium type cast iron grinding ball is defined as the chromium content ranging from 3.0% to 7.0%, and the carbon content coming between 1.80% and 3.20%. Its impact value should be no less than 2.0j/cm. . The national standard requires the hardness of this type of product should be greater than or equal to 47hrc. For ensuring the quality, the medium chromium type product should be processed with high temperature tempering to eliminate the casting stress. If the surface of the steel ball assumes the dark red color, it proves that the steel ball has been processed with high temperature tempering. If the surface of the steel ball still comes with the metal color, then, we can judge that the steel ball doesn’t go through the high temperature tempering treatment.
