Chemical Injection Lance


Chemical njection lance is prolonged injection packer. Usual, injection packer apply for 5cm ~ 100 cm. A injection lance solve the problem of deep chemical grouting. Injection lance length from 1m, 2m to more. The injection lance have weldless body, which can burn high pressure. Not prone to breakage when chemical injection. No matter what kind of injection environment, high pressure or low pressure work, you can choose from us.

Data sheet

The injection lance is composite of spear head + weldless pipe body + grease copler.


Injection lance body specification

The lance body is made of ST52 steel, with good strength, toughness, good mechanical properties and processing performance.


C Si Mn P S Ni Cr Cu
0.17~0.23 0.17~0.37 0.35~0.65 ≤0.035 ≤0.035 ≤0.3 ≤0.25 ≤0.25


Grease head

The lance coupler have flat head, grease nipple. Following lance head information.

M16*1.5, M18*1.5, M20*1.5 etc.


Feature and advantage

  • The spear-shaped head makes it easy to put into the drill hole, saves manpower, and avoids breakage.
  • The connection have male and female joints, which can achieve longer and deeper chemical grouting injection.
  • The lance connection head have big ball, which is easy flowing the chemical materials.
  • The injection lance pipe is containing chromium elements, which has good corrosion resistance and mechanical properties. Thus the lance can inject various chemical grouting, such as hydrophobic polyurethane, hydrophilic PU, acrylic gel etc.


Supplying range

We can produce M13*1000mm, M13*2000mm, M16*1000mm, M16*2000mm, M18*1000mm, M18*2000mm, M20*1000mm, M20*2000mm injection lance. WIth connector clamp, the lance can be 5m.


Chemical injection lance application

The injection lance is apply for soil underground stabilization. With high pressure ram impact, chemical grouting materials can enter very small gaps.
