There are two primary types of expansion joints-metal and non-metallic or elastomeric. Metal expansion joints are constructed in a bellows configuration from thin-gauge material designed to absorb mechanical and thermal movement. Elastomeric expansion joints, by contrast, are fabricated from natural or synthetic rubber and fabric. Consisting of an inner elastomeric tube fused to a metal-reinforced fabric body and an elastomeric cover, these types of expansion joints accommodate greater pipe movement and provide more abrasion resistance than metal joints.

1 Botanical characteristics
Young shoots and young leaves green, with light red additional color, thick hair; mature leaves large, thick, heart-shaped, 5 crack, deep cracking, upper lobes slightly overlapping, dark green leaves, dull, shallow back Green, sparsely villous; petiole short, reddish, petiole opener; annual mature branches purple-brown, stout, medium-long internodes, flat cross-section; mature winter buds full and prominent.
2 Economic traits of fruit Amphipathic flowers, natural falling flowers and light fruit; ear large and compact, mostly conical, general ear weight about 600g; fruit large, short oval, completely black after maturity, the average weight of about 16g, sparse After flowering and fruit thinning, the average grain weight can reach 18~20g; fruit powder is large, peel is thick, and fruit is not cracked; pulp is medium soft and hard (higher than Kyoho and rattan), soluble solids content is 18% to 21%, and it has rich strawberry. Aroma, basically no sour taste, good quality; each fruit contains 2 to 3 seeds, the seed is large; fruit handle and fruit combine tightly, not easy to crack; fruit brush thick and long, with a solid, resistant to storage and transportation.
3 growth results Habits early fruiting period, the general result of the second year after planting. Mature trees grow vigorously with a germination rate of 80%. The result is a branching rate of 95% with an average of 1.6 spikes per fruiting branch. The fruit is mature. It is also easy to color in years when there is a lot of rain and lack of light, and if the fruit is 2 times or 3 times, it can reach deep black even after frost, which is an extremely rare phenomenon in the Kyoho line.
In the southwestern Shandong Province, the general year of early April sprouts, flowering around May 20, mature in the middle and late August, about 15 days later than Jufeng, and about 20 days later than Fujieda.
4 adaptability and disease resistance cold resistance, mature shoots can withstand -18 ~ -20 °C low temperature. The disease resistance is extremely strong, and the conventional management means no pests and diseases occur. High-yield and stable production, large spikes and grains can be comparable to Fujimaki, and its coloration, quality, and storage and transportation are all superior to Fujimaki. It is a new generation of improved seeds with better comprehensive characters after Fujita, which not only adapts to most northern regions. The cultivation is also fully adapted to the cultivation of high temperature and rainy areas in the south.

Expansion joints reduce vibration, dampen sound, and accommodate movement in piping systems.
Kaochi Grape was developed by the Yamashita Komatsu of Japan's Nagano Prefecture, and was registered with the Japanese Ministry of Agriculture, Forestry and Fisheries in 1992. European and American hybrids, tetraploid. In February 1995, we introduced this type of scion from the Korea New World Breeding Garden and grafted it on a large tree at Kyoho, with a spacing of 2m×4m and a small scaffold. In the period of high yield in 1997, the average yield was 26kg, equivalent to 2158kg per 666.7m2 (mu), and the trial sale price in the county was 10 yuan per kilogram, which was 4 times that of Kyoho and 2 times that of Fujimaki. In the spring of 1998, it was promoted and replanted in Jinxiang County, Shan County and other places, and the planting area was 6hm2 (ha). Its comprehensive performance is now reported as follows.
