Purchasing Guide

Based on real user feedback, we provide the following suggestions:

  • For procurement requirements that require the use of direct connectors, it is recommended to prioritize checking key technical parameters such as interface size and pressure rating to ensure compatibility with existing pipeline systems and avoid installation failure or leakage risks due to specification differences.
  • When using straight through joints in industrial fluid transportation or hydraulic systems, it is necessary to select the appropriate material based on the characteristics of the medium (such as corrosiveness, temperature range). For example, stainless steel joints are suitable for high corrosion environments, while carbon steel is more suitable for conventional working conditions.
  • When selecting suppliers, priority should be given to indicators such as product compatibility, business qualifications, enterprise activity, industry performance, and industry data support to ensure that suppliers can provide stable straight through connectors that meet technical requirements.
  • The structural design of straight through joints (such as thread type and sealing form) for different scenarios such as pre embedded building pipelines or quick connection of mechanical equipment needs to be evaluated based on practical operational convenience and sealing requirements.

Knowledge Base

Q

The selection of sealing materials for coal machine straight joints needs to consider multiple factors comprehensively. Hydraulic system pressure is an important factor. In high-pressure systems, it is necessary to choose sealing materials with high strength and high pressure resistance, such as nitrile rubber in rubber sealing rings. It has good oil and pressure resistance, can withstand high pressure, and ensure sealing effect; For low-pressure systems, relatively soft sealing materials such as silicon can be chosen

Q

Baidu AiGou has found pictures related to different categories of direct terminal connectors for you, taking you to appreciate the diversity and uniqueness of direct terminal connectors. At the same time, we also recommend high-quality direct terminal connector products for you, allowing you to easily and quickly find the most suitable direct terminal connector for yourself when making purchases.

Q

Stainless steel straight joint is a type of pipe fitting that connects two adjacent parts of a pipeline at each end, achieving seamless connection between pipelines. Its jacket (also known as a sleeve) is usually clamped by springs on both sides of the pipeline, which pressurizes and seals the fracture between the two pipe sections, thereby achieving a straight through effect of the pipeline. The main body is made of stainless steel material, which has corrosion resistance, high strength, high temperature resistance, and wear resistance
