Feature

1. Best Drinking Water Pipe
SPD ES, ED pipe is a combination of the polyethylene pipe and the steel pipe. As polyethylene's chemical and physical properties are quite stabilzed, and PE pipe is inserted inside of a steel pipe--creates many outstanding features such as preventing erosion, any rust or scales due to its inside insulating material, and keeping a high standard of hygiene for your drinking water.

2. Stabilized Quality
SPD pipe maintains a high standard of stability because it is made and jointed under a very strict quality control according to the regulations of ASTM 1248(for the polyethylene waterworks pipe) and ASTM A53(for the galvanized steel waterworks pipe)

3. Stong Coher
Coherence than ASTM Specification(2.0kgf) over 100% and can be screwed and drilled.

4. Superior Features
The combination of ASTM A53 specification and ASTM Specification allows SPD pipe to have superior features such as tensile strength, bent, flat, shock and strong hardness. Also polyethylene inside the pipe can keep its property upto, -45캜

5. Permanent Lifetime
Steel pipe protects PE pipe from the ultraviolet rays and extends PE pipe's lifetime to 50 years.(Test result obtained according to ASTM 1598, ASTMD 2837)

6. Superior Earthquake-proof
The SPD pipe is an earthquake-proof product as the PE pipe has an excellent elasticity and flexibility and the steel pipe is physically and mechanically stabilized. (PE pipes were safe from the earthquake in Kobe, Japan.)

7. Easy Installation
Because the SPD ES, ED has been strongly attached and uses mechanical joint materials such as P.M joint, it is easy for you to install the pipe by cutting and screwing without welding or other processing.

1.Hygienic Drain Water Pipe
SPD VS, VE drain water pipe consists of the waterworks PVC pipe (ASTM Specification) and the carbon steel pipe(ASTM Specification)or equivalent. As PVC pipe has storng heat-resistant and chemicla-proof features and is attached to the inside of the steel pipe, SPD drain water pipe is definitely anti-corrosive, light and lessens noise, as well as has good material property of earthquake-resistance.

2. Perfect Corrosion-proof
As SPD drain water pipe does not cause any corrosion and scale when it discharges drain water, the inside of the pipe never shrin ASTM from corrosion.

3. Low Noise Drain Water Pipe
As PVC pipe with the thickness of over 2t combined with the carbon steel pipe absorbs the noise when drain water flows inside it.

4. Economical Drain Water Pipe
Because the length of SPD drain water pipe is 6m, it saves joint material, And its weight is one half of ordinary cast iron pipe, so it is easy to install, Futhemore, its surface is made of steel, pipe, it does not need additional warm keeping material.

5. Easy Installation
It is easy to install SPD drain water pipes because they are easily cut and joined with no-hub fittings, MD(flage type)and PVC joint material.

6. Superior Earthquake-proof
SPD PVC drain water pipe is earthquake-proof as the chemically stabilized PVC pipe is jointed inside of the steel pipe that is mechanically and physically stabilized. And it is even stronger against tensile strength, horizontal shock and other outside pressure than the ordinary cast iron pipe.

7. Permanent Lifetime
As the inner PVC drain water pipe prevents corrosion and scale from the pipe, it does not cause the decrease water flow. And the corrosion-proof feature guarantees permanent lifetime.
