How to distinguish the quality of stainless steel clamping pipe fittings

As stainless steel clamping pipe fittings enter people's lives, the market scale is getting larger and larger, and consumers' recognition of it is getting higher and higher. In the face of such high demand, there are many products with quality problems mixed into the market. When consumers choose stainless steel pipe fittings, they need to understand their quality. Here is a brief introduction to you.

The quality of stainless steel clamping pipe fittings with different quality can be identified from the appearance. The good quality pipes generally have the following characteristics:

1. should be sharp, even and shiny.

The core of the

2. stainless steel clamping tube should be neat, the wall should be uniform, and the fluid should be smooth.

3. should have low carbon content, corrosion resistance, oxidation resistance, pressure resistance and strong toughness.

When the 4. is touched by hand, the tooth front is smooth and the processing depth is standard.

5. pipe fittings must undergo strict mechanical treatment before they can be sent out of the warehouse, so there is no debris on the surface of the pipe fittings.


Inferior stainless steel clamp type pipe fittings also look very bright, but the surface brightness may be low. Generally speaking, inferior stainless steel clamp type pipe fittings have the following characteristics:

1. thread can not see gloss, gray, and feel bad.

The 2. is rough, the tooth pitch is irregular, the tooth rod is not sharp, thick, the tooth rod is damaged, and it is easy to leak water.

3. surface rough, untreated, easy to oxidize.

4. wick is crooked, wall thickness is uneven, easy to block after fluid.

5. high carbon content, corrosion resistance, poor toughness, weak resistance.

The stainless steel clamping pipe fittings we use are made of stainless steel, and the commonly used stainless steel materials are 304 and 316. 304 stainless steel double card pressure parts have been on the market for a long time. The performance of 316 material is better than that of 304 material, so the price is more expensive than 304. Therefore, to judge whether stainless steel clamp type pipe fitting is made of 304 or 316 stainless steel, stainless steel material can be used to quickly identify reagents, which is a relatively simple and fast method.
