- Economic Quick and easy Installation even for unskilled workers.
- Installation Easy and convenient installation even in narrow ceiling spaceIt is easy to install even in a narrow space with many obstacles such as ducts.
- Convenience The existing steel piping system is complicated and difficult construction environment due to screw joint and welded joint. However, SP-joint of DAEJIN INDUSTRIAL CO. manufactures and supplies the product length according to the installation location, so it is very convenient to install during piping work
- Work Finish SP-JOINT is easy to adjust the top, bottom, left and right dimensions of the ceiling and sprinkler head at the bracket installation position and the ceiling finishing work is precisely adjusted, so installation work is beautiful
SP-JOINT is divided into a tubular type and a warm-keeping type, and it is classified into a screw type and a gear type according to the vertical adjustment method of the bracket. Especially apartment fire-fighting equipment has screw type bracket and high-level bracket which is one step ahead of construction work. The elbow bracket is easy to install even for unskilled workers. It is an excellent product with various effects such as castability and shortening of construction period.
tubular type
- It has a flexible crease with corrosion resistant stainless material and is the most economical product with exposed flexible parts.
warm-keeping type
- It is an economical product which can shorten the construction period by inserting the insulation material in the flexible part, eliminating the need for thermal insulation during installation.

C-PVC pipe is a heat resistant rigid vinyl chloride pipe that dramatically improves the heat resistance of polyvinyl chloride with its excellent chemical resistance, corrosion resistance and construction properties. It has very low thermal conductivity and low heat loss, prevents condensation and prevents damage to walls and structures. In addition, there is no proper leakage current because of good electrical insulation. It is easy to handle because it is lighter than metal products, and it is possible to work even in a narrow space because of easy connection and separation. In addition, there is no corrosion or scale, and it does not obstruct the water hole of the sprinkler head like iron pipe, so it can be used semi-permanently.
