Product description

Steel pipe nipples are made of steel pipes and are used to connect pipes with external threads at both ends, grooves at both ends, grooves at one end and external threads at the other end, chamfered at one end and grooves at the other end, chamfered at one end and threads at the other end, plastic-lined insulating joints, etc.

Customer challenge

Soil is prone to pollution

There is no oil connection and chip removal device on the construction site, and oil and iron chips are easy to cause soil pollution.

Prone to leakage after installation

The threading machines used on the construction site are all simple threading machines. Although such equipment is easy to use, it has the defects of poor thread processing quality (thread tightening, broken teeth, thread deviation, etc.), and the parameters such as tooth angle, tooth height and thread diameter cannot be guaranteed, which is easy to cause leakage after installation.

Difficult to machine

On-site processing on the construction site is directly threaded after cutting the pipe, without chamfering;

Prone to clogging/blockage

Most of the pipes cut on the construction site are cut by simple rolling extruders or toothless saws. Rolling extruder cutting has problems of shrinkage and internal burrs; toothless saw cutting has problems of internal burrs and blocking the pipe mouth. After installation, such products will affect the fluid flow and cause problems such as pipeline blockage.

Product function

Fluid transport function

Protection function

Steel pipe nipples are mainly used in fire protection systems, drinking water supply pipelines, HVAC fields, gas pipelines, power pipelines, construction, oil and gas and other fluid transport fields in China. For liquid transport: water supply and drainage; for gas transport: coal gas, steam, liquefied petroleum gas.

Electric steel pipe nipples are mainly used in the field of wire and cable transportation to protect and guide various conductors and cables, and as equipment grounding conductors.

Value advantage

Plastic-lined nipples

The nipples have good corrosion resistance in water, and the plastic lining layer in the pipe fittings acts as an anti-corrosion layer to prevent destructive electrolytic corrosion between different metals.
Grooved steel pipe nipples

We have self-designed automatic groove processing equipment to eliminate quality defects such as ellipse and bell mouth, so the efficiency is high and the quality is reliable.
Threaded steel pipe nipples

We can process straight threads and tapered threads according to customer requirements, and can process American standard threads, British standard threads, Japanese standard threads, etc. According to the standards of different countries, we can develop thread processing equipment by ourselves, with high product precision and good quality.
