Weld-On® 717™ Low VOC PVC Solvent Cement, High Strength, Heavy Body, Medium Set, Gray, 1/2 Pint

Weld-On® P 70™ is an industrial grade, low VOC emission, non-bodied, fast-acting primer. The strong, aggressive action of Weld-On® P 70™ primer rapidly softens and dissolves the joining surfaces of PVC and CPVC pipe and fittings. The benefit of this priming action is especially noticeable on parts being joined together in cold weather. Available in clear and purple; the latter allows easy identification when used on the joining surfaces. Weld-On® P 70™ primer, when used in conjunction with appropriate Weld-On® solvent cements, will make consistently strong, well-fused joints. It is essential that the joining surfaces of pipe and fittings be softened and remains softened prior to assembly. The main function of the primer is to expedite the penetration and softening of the surfaces. Its rate of penetration into the joining surfaces is more rapid than that of solvent cement alone. Weld-On® P 70™ primer is suitable for use with all types, classes and schedules of PVC and CPVC pipe and fittings. It is specially recommended for use on Schedule 80 and large pipe sizes. Weld-On® P 70™ has a shelf life of three years in a tightly sealed container.

Schedule 40 PVC corrosion resistant pressure pipe, IPS sizes 1/8-24, is ideal for use in applications with temperatures up to and including 140 degrees F. Pressure rating (120 psi to 230 psi) varies with pipe size and temperature. It is generally resistant to most acids, bases, salts, aliphatic solutions, oxidants, and halogens. Chemical resistance data is available and should be referenced for proper material. Schedule 40 PVC pipe exhibits excellent physical properties and flammability characteristics. Typical applications include: chemical processing, plating, high-purity applications, potable water systems, water and wastewater treatment, irrigation and agriculture along with many other industrial applications involving corrosive fluid transfer. Schedule 40 pipe is not recommended for threading or grooving. If threading is required for the application, solvent-cemented male or female adapters should be utilized. If grooving is required, solvent-cemented grooved adapters are available in limited sizes.Do not test or use PVC piping for air or compressed gasses. Care should be taken to avoid ketones, chlorinated hydrocarbon, and aromatic solvents.

PVC is the most commonly used plastic material for manufacturing plastic pipe. It has a relatively high tensile strength and module of elasticity. These features make it stronger and more rigid than most other thermoplastics. It is also resistant to most acids, bases, salts, aliphatic solutions, oxidants and halogens. The joining methods for PVC are by solvent cementing, threading (Schedule 80 ONLY) or flanging. PVC has been used successfully in industries such as chemical processing, industrial planting, chilled water distribution, salt water, chemical drainage, irrigation systems and other industrial applications with corrosive fluid transfer. The pressure rating systems given are for solvent-cemented systems. When adding valves, flanges or other components, the system must be de-rated to the rating of the lowest component: threaded fittings are rated at 50% of solvent-cement systems; flanged fittings are rated at 150 psi; union fittings are rated at 235 psi. Please see manufacturers' recommendations for other ratings. Do not test or use PVC piping for air or compressed gasses.
