This practice describes procedures for handling and installing thermoplastic pipe and corrugated pipe in septic tank leach fields, curtain drains, and from the septic tank to the leach field. Proper installation ensures that the pipe will satisfactorily convey and distribute partially treated waste water to a leaching field for additional treatment and disposal by soil absorption. The curtain or perimeter drain will function to protect the soil absorption capacity of the leach field. Pipe should be stored with support from a flat surface to prevent the pipe from developing a permanent set. Care should be exercised during loading, unloading, and in transit because pipe may be damaged by abrasion and sharp edges. Because thermoplastics are temporarily softened by high temperatures, care should be taken under these conditions to avoid damage during handling operations. Coiled pipe is not recommended for use in leach fields because it is difficult to install at the proper grade and alignment; it is acceptable with special equipment installation. Pipe can reach comparatively high temperatures when exposed to the sun and this reduces the pipe stiffness appreciably. Therefore, precautions must be taken to prevent the impact of sharp or heavy objects, the sudden imposition of heavy overburden or excessive pull on such pipe. The pipe regains full strength and stiffness as the temperature decreases to that of the soil; this will normally require about five minutes. Care in handling and installation should be exercised under low-temperature conditions to avoid damage. As temperatures decrease, some types of pipe tend to become more brittle and less flexible.1.1 This practice describes procedures for handling and installing thermoplastic pipe and corrugated pipe in septic tank leach fields, curtain drains, and from the septic tank to the leach field. Proper installation ensures that the pipe will satisfactorily convey and distribute partially treated waste water to a leaching field for additional treatment and disposal by soil absorption. The curtain or perimeter drain will function to protect the soil absorption capacity of the leach field.1.2 To ensure compliance with local regulatory provisions, the local approving authority (local health departments and so forth) should be contacted regarding specific requirements for leach field design materials and installation.1.3 This practice applies to pipe and fittings made under each of the following ASTM specifications:1.3.1 For transport from tank to leach field: Specifications D2680, D2729, D2751, D2852, D3034, F405, F758, F789, F810, F891, F892, and F949.1.3.2 Perforated, for use in leach field or curtain drain: Specifications D2729, D2751, F405, F810, F891, and F892.1.4 Pipe intended for installation in accordance with this practice should have a minimum pipe stiffness as specified in the appropriate product standard referenced in 1.3.1 or 1.3.2.1.5 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

5.1 This practice applies to materials manufactured in accordance with Specification C1729 (aluminum jacketing) or Specification C1767 (stainless steel jacketing). This standard is intended to provide a basic practice for installing these types of materials. Refer to Specifications C1729 and C1767 for information on the differences between aluminum and stainless steel jacketing and where each is considered for use.5.2 This practice is not intended to cover all aspects associated with installation for all applications, including factory and field fabricated pipe fitting covers.NOTE 1: Consult the National Commercial & Industrial Insulation Standards (MICA), Guide C1696, the product manufacturer, and/or project specifications for additional recommendations.5.3 Metal jacketing is typically used on insulated piping located outdoors, including, but not limited to, process areas and rooftops. Metal jacketing is used indoors where greater resistance to physical damage is required, for appearance, for improved fire performance, or as otherwise preferred. Metal jacketing used outdoors serves the same functions as indoors and also protects the insulation system from weather.5.4 Metal jacketing is used over all types of pipe insulation materials.1.1 This practice covers recommended installation techniques for aluminum and stainless steel jacketing for thermal and acoustic pipe insulation operating at either above or below ambient temperatures and in both indoor and outdoor locations. This practice applies to materials manufactured in accordance with Specification C1729 (aluminum jacketing) or Specification C1767 (stainless steel jacketing). It does not address insulation jacketing made from other materials such as mastics, fiber-reinforced plastic, laminate jacketing, PVC, or rubberized or modified asphalt jacketing, nor does it cover the details of thermal or acoustical insulation systems.1.2 The purpose of this practice is to optimize the performance and longevity of installed metal jacketing and to minimize water intrusion through the metal jacketing system. This document is limited to installation procedures for metal jacketing over pipe insulation up to a pipe size of 48 in. NPS and does not encompass system design. This practice does not cover the installation of metal jacketing on rectangular ducts or around valves and gauges. It excludes the installation of spiral jacketing on cylindrical insulated ducts but is applicable to metal jacketing on cylindrical insulated ducts installed similarly to pipe insulation jacketing. Guide C1423 provides guidance in selecting jacketing materials and their safe use.1.3 For the purposes of this practice, it is assumed that the aluminum or stainless steel jacketing is of the correct size necessary to cover the thermal insulation system on the pipe or rigid tubing while achieving the longitudinal overlaps specified in 8.2.2 and 8.3.2. The size of the aluminum or stainless steel jacket necessary to achieve this specified longitudinal overlap closure is a complex topic for which the detailed requirements are outside the scope of this practice. Achieving this fit is very important to the performance of the total insulation system. See Appendix X1 for general information and recommendations regarding this closure of aluminum and stainless steel jacketing installed over thermal pipe and rigid tubing insulation.1.4 The intrusion of water or water vapor into an insulation system will, in some cases, cause undesirable results such as corrosion under insulation, loss of insulating ability, and physical damage to the insulation system. Minimizing the movement of water through the metal jacketing system is only one of the important factors in helping maintain good long-term performance of the total insulation system. There are many other important factors including proper performance and installation of the insulation, vapor retarder, and insulation joint sealant. Optimum long-term insulation system performance is only achieved by carefully considering all aspects of insulation system design and how these relate to the intended application (hot, cold, cryogenic, severe environment, etc.). This practice only addresses installation of metal jacketing so total insulation system design is outside of its scope.1.5 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use.
