The MSS SP-97 standard covers the design, production and quality control requirements of socket welded branch stations in carbon steel, alloy steel and stainless steel with diameters ranging from 1 2 inches to 48 inches. As an important part of the industrial pipeline system, the branch pipe table is mainly used to open branch pipelines on the main pipeline or connect with other equipment, and is widely used in pressure pipeline systems in oil and gas, chemical industry, electric power, nuclear energy and other industries.
Key elements
Material selection and performance requirementsAccording to the MSS SP-97 standard, the branch table should be made of materials that meet the corresponding strength and corrosion resistance, including strict chemical composition restrictions and mechanical property indicators.
Design & DimensionsThe standard stipulates the design parameters of the main structure of the branch pipe table, such as the inner diameter of the main pipe, wall thickness, insertion length, branch pipe size, and the geometry and tolerance of the socket, etc., to ensure that it achieves good fit and sealing with the main pipe and other connecting components.
Manufacturing processThe manufacturing process of the branch table needs to follow strict operating procedures, including a series of steps such as casting and molding, forging, welding, heat treatment, surface treatment, etc., to ensure the quality and reliability of the product.
Inspection Methods and Acceptance CriteriaBefore leaving the factory, the branch table needs to pass a series of tests, including but not limited to visual inspection, dimensional measurement, non-destructive testing (such as radiographic testing, ultrasonic testing, etc.), mechanical performance testing and functional verification testing. Only products that meet the acceptance criteria specified in the MSS SP-97 standard can be placed on the market.
Identification & CertificationAccording to the MSS SP-97 standard, each branch station product should be clearly marked with the material grade, dimensional information, manufacturer name, batch number and necessary safety markings, and accompanied by complete quality certification documents.
Fields of application
Branch tables manufactured in accordance with the MSS SP-97 standard are used in a wide range of demanding industrial environments and play a vital role in improving the safety, stability and efficiency of the entire piping system. Strict implementation of this standard will help improve product quality, prolong service life, promote technical exchanges and cooperation in the industry, and promote the sustainable and healthy development of related industries.
In summary, the MSS SP-97 standard sets a unified and strict standard for the design, production and inspection of the branch pipe table, which effectively guarantees the reliability and safety of the branch pipe station under various complex working conditions, and is an important guiding basis for the design and manufacture of the branch pipe table for socket welding connection worldwide.
