包覆墊片Covering gasket

　  包覆墊片主要用途：適用于直徑較大的壓力容器(如換熱器、反應(yīng)器等)法蘭的密封。各種介質(zhì)的機(jī)泵、管閥、管道及各類設(shè)備的法蘭等密封。適用于中、低壓工況。

      The main purpose of the covering gasket is suitable for sealing the flange of larger diameter pressure vessels, such as heat exchangers and reactors. All kinds of media such as pumps, valves, pipes and flanges are sealed.Suitable for medium and low voltage conditions.

波齒墊片Wave tooth gasket

      齒形組合墊尤其適合于高溫、高壓，工況條件交變的場合，在熱交換器、容器的法蘭連接處，是傳統(tǒng)金屬包覆墊片的理想替代品。

      The wave tooth gasket is especially suitable for high temperature, high pressure and alternating condition conditions. It is an ideal substitute for the traditional metal coated gasket at the flange connection of the heatexchanger and the container.

纏繞墊片Spiral Wound Gasket

      纏繞墊片特別適用于負(fù)荷不均勻、接合力易松弛，溫度與壓力周期性變化、有沖擊或震動的場合。纏繞墊片是閥門、泵、換熱器、塔、人孔、手孔等法蘭連接處理想的靜密封原件。

      The spiral gasket is especially suitable for occasions with uneven load, easy joining force to relax, periodic change of temperature and pressure, impact or vibration. Spiral wound gasket is the ideal static seal for valves, pumps, heat ex changers, towers,manholes and hand holes.

非金屬墊片Nonmetal gasket

      主要應(yīng)用在水、蒸汽、油類、溶劑、中點酸、堿等密封以及中、低壓法蘭的密封中。

      It is mainly used in sealing of water, steam, oil, solvent, midpoint acid, alkali, and medium and low pressure flange.

金屬環(huán)墊片Metal ring gasket

      金屬環(huán)墊片有三大特點：耐高溫、耐高壓，適用于高壓法蘭；密封持久可靠；適應(yīng)載荷頻變的工況條件。

      The metal ring gasket has three main characteristics: high temperature resistance and high pressure resistance. It is suitable for high pressure flange. The sealing is durable and reliable.

金屬平墊片Metal flat gasket

      金屬平墊片由整體金屬經(jīng)機(jī)加工制成，用于壓力容器、塔、槽、閥蓋等部位的密封。主要有鋁平墊、紫銅墊、不銹鋼墊。

      The metal flat gasket is made of integral metal machined and used for sealing parts such as pressure vessels, towers, grooves and bonnets. There are aluminum flat pads, copper pads and stainless steel pads.
