Product Introduction

The MSS-SP-112 Hex Bushing is a pipe fitting manufactured in strict accordance with the MSS-SP-112 industrial standard, and its main function is to realize the stable connection between pipes with different nominal diameters in the piping system. The MSS-SP-112 Hex Bushing adopts a hexagonal external structure, which not only allows the use of tools for fastening operations during installation to minimize the risk of deviation but also maintains a stable connection state during long-term use to prevent medium leakage caused by loosening. Compared with non-standard bushings, the MSS-SP-112 Hex Bushing has better compatibility with other pipe fittings on the market due to its standardized characteristics.

Product Advantages

1. Simplify procurement and inventory management: As it conforms to the MSS-SP-112 universal standard, it can be purchased in batches without separate stockpiling for special specifications, reducing the capital occupied by excess inventory.

2. Enhance replacement compatibility: Its standardized structure enables compatibility with other pipe fittings of the same standard on the market, eliminating the need for redesign or customization during replacement.

3. Ensure stable performance consistency: Produced in accordance with the MSS-SP-112 standard, it has stable dimensional accuracy and sealing performance, reducing the risk of pipeline leakage caused by unqualified fittings.

Application Scenarios

1. Petrochemical Piping Systems: Used in pipelines for transporting crude oil, refined oil, or chemical media to connect pipes of different diameters and meet the sealing and pressure resistance requirements of the system.

2. Municipal Water Supply and Drainage Piping Systems: Applied in urban water supply, drainage, or sewage treatment pipelines to connect pipes of different specifications and ensure the stable transportation of media.

3. Industrial Steam and Compressed Air Piping Systems: Suitable for pipelines transporting pressure media such as steam and compressed air in factories, ensuring the long-term safe operation of the system with its standardized structure and reliable performance.

FAQ

Q: Can the MSS-SP-112 Hex Bushing be used in pipelines transporting corrosive chemical media such as sulfuric acid or hydrochloric acid?

A: Yes, it can, but the material of the fitting must be carefully selected. For example, when transporting 30% concentration sulfuric acid at a working temperature of 50℃, the 316 stainless steel MSS-SP-112 Hex Bushing should be selected, as 316 stainless steel contains molybdenum elements that can improve corrosion resistance to acidic media. However, for high-concentration hydrochloric acid (above 37%), it is recommended to use Hastelloy material MSS-SP-112 Hex Bushing to ensure long-term corrosion resistance.

Q: When installing the MSS-SP-112 Hex Bushing in a high-temperature steam pipeline (working temperature 350℃), what precautions should be taken to ensure the connection tightness?

A: First, select the MSS-SP-112 Hex Bushing made of high-temperature resistant material, such as A350 LF2 alloy steel, which can maintain stable mechanical properties at 350℃. Second, use high-temperature resistant thread sealant (e.g., PTFE-based sealant with a maximum temperature resistance of 450℃) instead of ordinary sealant to prevent sealant failure at high temperatures. Third, control the tightening torque during installation; for example, for a 2-inch NPT thread MSS-SP-112 Hex Bushing, the tightening torque should be controlled at 80-100 N·m to avoid thread damage caused by excessive torque or insufficient sealing caused by insufficient torque.
