Special-purpose manways – general information

Special-purpose manways is a product category that includes manways suitable for installation in tanks other than those made of stainless steel (except for products in the subcategory "manways for industry and energy"). In the case of special-purpose manways, the most important construction element is the mounting frame, which, depending on its design, may have different purposes.

Special-purpose stainless steel manway
Special-purpose round manway

Among the special-purpose manways, the following groups are distinguished:

  • manways for wooden tanks (barrels),
  • manways for concrete/cement tanks,
  • manways for plastic tanks,
  • manways for industry and energy sector.

Individual adaptation of technical designs

A distinguishing feature of special-purpose manways is the fact that they are not serial products Thus, the vast majority of manways in this category are manufactured to individual order. This situation creates favourable conditions for partial customisation of the product to meet individual project needs.

 

Preparation of a custom manway design includes:

  • accurate demonstration of technical requirements by the ordering party,
  • analysis of the requirements by the technical department and preparation of the corresponding technical configuration of the manway,
  • providing technical design of the manway,
  • production of the unit as designed.

Custom solutions of this type are particularly valued by engineering companies that design and manufacture custom structures.

Application of special-purpose manways

Special-purpose stainless steel manways are used in almost all industries, where it is necessary to use a closure enabling inspection inside a tank or device. Thus, the possibilities of using special-purpose manways are limited only by their parameters and construction requirements.

 

Please note, however, that most of the manways in our offer are designed to be used in food processing plants (unless otherwise indicated in the product description).

 

Examples of special-purpose manway applications:

  • as a cement tank lid for non-food grade water in manufacturing plants,
  • as an inspection part in wooden barrels (used for example in wine production),
  • as a maintenance opening in specialised agricultural machinery.

A separate group of special-purpose manways are models designed for work in potentially explosive atmospheres (ATEX).
